How can a TKEY messenger allow you to send funds anywhere in the world without commissions and in a matter of seconds?

Yesterday was the official release of the new flagship product — Tkey Messenger. Messenger is available in the browser and on desktops for the most popular systems Windows, macOS, and Linux. Soon, smartphone owners will be able to try out Tkey Messenger in action, the app will appear in the App Store and Google Play.
https://preview.redd.it/f4ca4g0nue651.png?width=1400&format=png&auto=webp&s=c857c896bf71771e3d01e0210f24da9a4fb68887
In the era of rapid communication and technology development, messengers have become our default products. We use them for business purposes, to communicate with friends and acquaintances — this has long been the norm. It would seem that why are other messengers created when there are many other instant messaging systems?
Today we will talk about what a Tkey Messenger is, what it can do today, what features will be included in it in the future, and most importantly, what we are creating It for and how we will develop it.

TKEY.ME

The abbreviated name of Tkey Messenger is tkey.me. First of all, TKEY-ME is a secure messenger with p2p audio and video calls, and in the future, a built-in digital wallet.
“Every day we communicate in messengers. We earn money at work. We make purchases and transfers. We are here to combine these processes in one application and make sending funds as easy as sending a message”

The Tkey Messenger as a new ecosystem

Do you think we are here to compete with other messengers? — No, there are a lot of great messengers. We are here to create our ecosystem and the internal market in it. Combine these processes in one application and make sending funds as easy as sending a message.
After all, we work in the field of FINTECH, cryptography, and blockchain, why not apply the best practices and knowledge in practice? Therefore, the TKEY Messenger should be considered for a large ecosystem.
This is a new payment segment that covers fast communication tools in combination with an internal payment system, a set of exchange practices, blockchain, cryptography, our own experience, and the experience of global companies.

How will the Tkey Messenger ecosystem work?

https://preview.redd.it/17bml1zpue651.png?width=1400&format=png&auto=webp&s=99ebd70745968452536546fb5a59841e8f3a9c52
Let’s start with the most important thing: money should be sent in a matter of seconds, regardless of the country of issue of the Bankcard and wherever you are.

Here is a simple example:

You or your relatives live abroad and you want to send funds quickly, for example, 2600 USD — you just open a chat with your loved one, send a message and 2600 USD in the same second become available on your loved one’s account.
https://preview.redd.it/nmz4ienrue651.png?width=697&format=png&auto=webp&s=c3902fc0df1ed2eba425c3f3db3eb8c40bc7a237
It turns out that you can exchange Tkeycoin for USD, EUR, or GBP in a matter of seconds, as well as instantly send them to any place in the world and without hidden fees, the exchange amount is immediately available on the screen.
Or you have Bitcoin, and the Recipient needs dollars — Tkey Messenger will take care of all the complex tasks, you will only need to send a message to make the payment.
Each completed payment will be processed through a digital payment system without Bank intervention. You can link your Bank card to automatically withdraw digital funds to your local currency.

Do you want to simplify payments even more?

Order a TKEY card, and it will automatically be linked to your Tkey Messenger account. Make payments online, make purchases in stores — it’s just as easy as you did before, only much more convenient, faster, and safer.
https://preview.redd.it/42f1dkktue651.png?width=1400&format=png&auto=webp&s=7305192230c379c0fe81d981208a8cef8a540a5c
The most important thing is that you can easily use digital assets in combination with Fiat currencies — just top up your account in messenger to start sending currency around the world.
“Moving money around the world should be as easy and cheap as sending a message. It doesn’t matter where you live, what you do, or how much you earn.”

Send TKEY or Bitcoin via message, has it become a reality?

In Tkey Messenger, you will be able to quickly send digital currency using a message. You can not specify a public address, but send a digital currency using a message.
Instantly send funds to friends or relatives anywhere in the world. No Bank, no problems, no hidden fees.

Top up your mobile phone or pay for the Internet?

The usual payments, such as the Internet or mobile payments, will certainly be available, because if we can transfer pounds from England to Canada in a matter of seconds, and the recipient will receive dollars, why can’t we make a payment for the Internet? “Of course you can.

Transfer funds by a nickname

You don’t need to know the recipient’s account, just send funds by their nickname to the Tkey Messenger, and the funds will arrive within a few seconds. Fast, convenient, and safe.

What do we get in the future when using a Tkey Messenger?

We get an ideal payment system with instant transactions, fast access to various currencies, including digital, instant international payments, a huge platform for business, a marketplace with trusted sellers, secure transactions, while fast communication, p2p calls, and video communication. Not to mention various chips, in the format: cashback, savings account, invest. products, etc.
  • International transfers without Commission and in seconds;
  • Instant account opening — just create an account to get access to payments;
  • Access to funds 24/7/365 wherever you are.
  • Multi-currency wallet — you can use both digital currencies and classic currencies, such as the pound, euro, and dollar.
  • Payment in digital currency anywhere in the world.
  • Save time and money.

How is this possible, you say?

More than real, we will answer. At the very beginning of the project, we planned to create a marketplace, and then finalized the concept with NFC payments in TkeyPay. Smoothly, all this develops into a single system, which will be merged into a Tkey Messenger.
The Tkey Messenger is convenient and secure, payment system, and marketplace. The entire financial industry is in your hands-in your smartphone.
https://preview.redd.it/ullvuelexe651.png?width=1001&format=png&auto=webp&s=ef883fa9de067b885138a231069ddc3c0414c7d3
The mobile Finance industry is developing rapidly against the backdrop of a growing number of Internet users and the increasing role of smartphones in modern life. Today, the mobile device market attracts about 2 billion people, who remain passive players in financial markets.
With the Tkey Messenger access, you always get access to instant Finance, shopping, and the nice things you want to get here and now. In practice, it has turned out that we can often forget the keys to the apartment, rather than the phone, so your finances will always be with you.

Join the global Tkey Messenger system right now

Release 1.0.0 is available in the web version and for Windows, macOS, and Linux operating systems, and shortly on your mobile devices.

Current functionality of Tkey Messenger 1.0.0

The Tkey Messenger version 1.0.0 is the core that opens up new features that we discussed above, payments, and more. Now it is a convenient and stylish messenger with an intuitive design, instant messaging, and secure audio and video communication.

The P2P audio and video calls in a Tkey Messenger

When creating the first version, we focused on high-quality video and audio communication. Now you can easily call by video and be sure that you will get a high-quality video stream, as well as the absence of restrictions from third parties because the connection is carried out on the principle of p2p.
Audio and video calls are made in p2p mode, so there is no recording of calls at all.
https://preview.redd.it/lyrnkfhgxe651.png?width=1384&format=png&auto=webp&s=fb0c93ca45fa6bd4f65c77f64c81b88b906e904a
You can chat with friends and colleagues around the world for free, and excellent audio and video quality will only positively affect the quality of your conversation.

Calls in the web version

The web version of Tkey Messenger is available at → http://web.tkey.me/. The web version has full call functionality, so you can easily call through it, both via video and audio.
Video calls are available with the “Share” function, you can easily “share” your screen for the interlocutor and show what is happening on it. This function can be used for presentations or training events.
Screen Sharing is a demonstration and broadcast of the screen. “Share” your screen for the interlocutor and show what is happening on it.
https://preview.redd.it/x5h6au9ixe651.png?width=459&format=png&auto=webp&s=9b71b9148b17b55636c5615cbf7d6535cc78aa56

Group video and audio calls for up to 50 people

In the web version, you can launch a group video call. In the chat, tap the “handset” icon — the call will be sent to all participants in the chat, so all participants in the group chat can hold a video conference of up to 50 people. The user can turn on the camera and not turn it on, but simply participate in a video conference via audio.
On average, messengers that support the function of video calls in high quality, hold a video stream of no more than 8–10 people. In a Tkey Messenger, group conferences support up to 50 people. Soon-public online broadcasts and streams.
On the call page, you can conveniently distribute the Windows of the connected video stream.
https://preview.redd.it/qf85k37kxe651.png?width=744&format=png&auto=webp&s=8074a48fca7ea492376460d5c15f1de27722f7ea

Unlimited private group chats

The first version only supports private chats and group chats. Group chats are also completely private, so there is no “Share” function, only the chat participant can invite another participant to the group chat.
Create your thematic chats. Work. Family. Friends. Be the first while we develop. Soon-public channels and chats.
Anyone can start an audio or video call, and the notification goes through all participants. Switching to audio or video mode can be switched right at the moment of the call.
As we have already mentioned, group chats are completely private. You can make video and audio calls, send messages, and invite other participants.
To invite a new chat participant, any user can invite another user to a group chat. To do this, click on the “three points” menu icon.

https://preview.redd.it/cyfuh6snxe651.png?width=428&format=png&auto=webp&s=ee38ed7f20fed0bcb576279a6701397cd777e913
Next, enter the nickname of the participant you want to invite to the group chat in the search.

Deleting information in group chats

Each participant, when they click the “Exit and delete” button, deletes messages and information from the chat on their side.
In group chats, all information is deleted by the last person to leave the group chat. After deleting-all messages, media, photos, and other data that were in this chat are automatically deleted. If all participants leave the group chat, it will be automatically deleted, and all information published in the group chat will also be deleted.

The chat between the two parties

This is a classic private chat between two participants, instant messaging, sending media.
The rights of the participants are equal. Any chat participant can delete the entire chat. after deleting all messages, media, photos, and other data that was in this chat, it is automatically deleted.

I got pwned: a cautionary tale

As background, I've been playing with a Digital Ocean instance for the past few months - getting DNS and Let's Encrypt set up, setting up nginx as a reverse proxy, and now setting up nextcloud.
Last week, I was pretty pleased with myself. I installed the Calendar plug-in and started syncing my calendar - independently of Google! Today I started getting from 500 errors popping up on my phone. I didn't think much of it - I figured something was weird with nextcloud, I had overlooked something, and I could figure it out when I got home. Unfortunately, I just found this in my database.
centos:~/src/nextcloud-config$ mysql -h 172.20.0.1 -P 3306 -u nextcloud -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g.

I have no intention of paying the ransom. 1) They have a few calendar events and some example documents from me. 2) Even if I pay, there's no guarantee they would send me a copy of the data.
All things equal, I feel lucky this happened so soon ... I only lost like 3 calendar events, all of which I can recreate from memory. I guess I need to back up and re-evaluate my security assumptions (notably to make backups early).
In the hopes of detecting the root cause, here is my (redacted) nginx access.log from today: https://pastebin.com/JQ64ctcG Naturally my judgment is in question, ha ha, but I did see a few suspicious-looking entries (some suspicious-looking stuff in there (github.com/robertdavidgraham/masscan, some calls to /login and /wp-admin, some requests that look like binary data...). If anyone could help me understand how my server was compromised, it would be much appreciated.
Thanks all ... remember that weird shit like "entire Internet scanner" exists ... :-(
edit: Thank you all so much. Based on the ideas from the comments, the prevailing hypothesis about the root cause is:
- no firewall was active, either through the host admin panel (Digital Ocean) or in Linux itself
- In the course of troubleshooting, I had exposed port 3306 on my database container to anyone with access to my droplet, i.e. the whole Internet (via DNS). My intention was to expose the port only to other processes on my droplet, but I unintentionally exposed it publicly.
- I had an extremely weak root password
- With the "masscan" port-scanning tool, the vulnerability was detected by an attacker quite quickly, like within a week of me having this configuration active. Then a simple dictionary attack would have let them into root in my mariadb container.
Well ... knowledge is half the battle. Thanks again everyone ... I hope this thread will help a future lost soul who finds themselves in a similar circumstance.

Laffka opensource torshop+bitcoin

Laffka opensource torshop+bitcoin
14.8 For sane instructions, please refer to https://github.com/eruina/laffka, most relevant technical stuff is in README.md - https://github.com/eruina/laffka/blob/masteREADME.md
14.8 RELEASE 2.01
pip3 -r requirements.txt
nano app/configuration.py
nano app/templates/disclaimer.html
python3 laffka.py
https://github.com/eruina/laffka
10.8 Made one test sale, spores for for microscopy in syringe.
Can confirm, payment of mailing expenses made to my wallet rapidly and without problems.
Proof:https://www.blocktrail.com/BTC/address/1FwJdVgMZHK6WWX9t9GJnBnSVrSqfqkARB/transactions
Revamped site, welcome: http://laffka6wwduoexvb.onion/
source code will be availible 12.8
Revamped sitehttp://laffka6wwduoexvb.onion/
9.8 Items can be added, removed and edited from console panel:
Console item
And this is how it looks like listed: http://laffka6wwduoexvb.onion/item/6
Listing
Custom list of amounts to ship is in use now, howver - admin console validates only if session authorized.
What does this mean? Means that putting wrong values into database might bring whole Laffka down. Especially amount lists and orders which include both MainNet and TestNet orders.
Temporary solution would be to implement /rescue page, where admin can delete any offending row from database. Bit lame, but would do for now.
I am also puzzled at in which form package is to make. Well, have 3 days to figure it out.
8.8 At very basic level Laffka works in very basic level without any external stuff. Here:
Second part of admin console
At the risk of being labeled pedlling crap - shop example on laffka should work: http://sporeikzj77hnrxq.onion/ (yes, it is fully working little shop)
8.8 Items can be changed from console now. One can change, but not add or remove items at the moment.
Ugly as hell, but admin console in fact doesnt need to be pretty.
it needs to be functional.
https://preview.redd.it/xqpdx0rn0ue11.png?width=1195&format=png&auto=webp&s=c495e2c89b59c7a0fcc35a2c123a83a8667c35d1
6.8 Orders part of console is finished. Orders shown - ones that are paid, and ones that are marked with note.
Rather nifty, but probably requires additional changes after code is released.
Orders page
Order 98 will be shown even if Wif key is swept. Order 99 will disappear after Wif key is swept. Simple, and probably will require additions, but would do for now.
Time to fiddle with items.
5.8 Something like this. Subject to change!
Console, early version
5.8 Admin console is a bit of a puzzle. At the moment, I think of showing orders that has been paid AND orders which has note left by admin. Should be sufficient for first release version.
I also deem it bit pointless at the moment to validate values of admin console forms, orders and items.
4.8 pip3 module requirements now include flask-login and flask-session.
It would be interesting to run few instances of Laffka with common order table. This way one can make and keep a lot of small darknetshops in hidden onion land, with overall price well under 50€.
Login and session are required for shopowner identification, means it is in progress, after which packaging only left.
It might be interesting to make liveusb with sole purpose of running small Laffka-torshop.
Word Laffka is from finnish Lavka, which means small shop, usually at market place.
2.8 I should mention, that purchase process is very nonintrusive for customer. Gives a bit strain to shop owner, but not much.
1.8 Meanwhile I suffer from heat and overuse of bandwith, here is small presentation, how payments work.
Suppose customer would like 3pcs of Test item 1:
Generic order of Test item 1
So, customer clicks 3pcs, and arrives at second page:
Address part of ordering
Finally customer arrives at personalized payment page
Check out
After which customer is asked to pay for order:
Electrum Testnet
After order being paid, payment reflects on orderpage(http://laffka6wwduoexvb.onion/pay/mryJ3ukrFHoUmdHeSkR4XZcwe3wvG3pRkd)
After payment been through:
Finished payment
Shop owner can claim funds by sweeping own private key from admin console(not finished yet)
Private key cUP4jznEGX8EDMPw813w4B7E6fBo3FDXPqhRLp5sFHq3v3KCgP2z
All right, now lets swipe:
Sweep-sweep.
Voila, New transaction received
Received payment
So, all in all customer paid 4.64526, and shop owner received 4.64108, difference is paid for bitcoin transaction, while private key was swept.
Nifty.
1.8 FFS. Seems I've depleted bandwith for august.
need to tune tor more careful.
UPDATE: temporarily example can be accessed at http://laffka6wwduoexvb.onion/. test22cq47 doesn't work for now.
1.8 Satellite skeleton is done, orders page in progress.
Makes sence to finish satellite with instructions after admin console is done.
Still fucking hot in here, coding advances very slow, yet I believe it is going to be finished before deadline, 12.8
31.7 Satellite is in works, meanwhile testshop can be found at http://test222cq47k6qrn.onion/
http://laffka6wwduoexvb.onion/ is going to point to project site itself, with sources and instructions.
31.7 My bad.Had theoretic items in a shop, and was considered peddling crap by administration.
Exchanged those to Test item 1 and 2, as seen here: http://laffka6wwduoexvb.onion/
Project is now hosted separatedly from development, and should be availible all the time.
Of course, since it is early Alpha, it can fall, but otherwise you are welcome to make test order and pay it with testBitcoins.
It is fucking hot here, literally cannot concentrate myself to do anything useful.There is but two things left before release:
  1. Admin console (for fiddling with items, and sending orders)Have idea how to elegantly handle orders, but not items
  2. Some form of ready to deploy package
Also, I must mention requirements. Installing whole thing on pristine CentOS 7.4 was under 15mins, so here are first requirements:Python3 and python3-pip
And pip requirements for now: flask, requests, Flask-APScheduler, Flask-WTF, bitmerchant
12.8 is still deadline for release.
29.7 Nifty!!!
Too hot to think about admin console, yet it is not harder to run few instances of Laffka on machine than typing:flask run --port=5678andflask run --port=6789
in two different consoles. Actually nifty. No conflicts, two absolutely separate instances having nothing to do with each other.One can already generate sales, yet database from admin perspective is accessible only from some DB Browser.
29.7 I have observed, that visitors are coming to payment page, where it asks address and then most probably close page.
Don't be afraid, type some stupid shit there, it will transfer you to payment page itself. Don't be afraid to pay order neither, since testBitcoins do not cost anything. Neither I receive any information, except routes of visitors.
Answering questions: Design is no priority whatsoever. Since Laffka is developed with Tor in mind, there is no graphical elements at all. May be later CSS will be tweaked and ability to add pictures to items, but I don't see myself developing cushy designs for Laffka.
It should be lightweight, fast and simple. Functionality is of priority here.
Then there is question "How can I participate". At the moment only by testing is a method or participation, ie making order and paying with testBitcoins. After first release, one can branch code and develop own branch. I am not yet ready to release first public version.
Before releasing, there is necessity to create make/setuptools.py
28.7 Hello.
Always wanted my own small shop on darknet, not consolidated markets, which are riddled with such problems as exit scams, DDOS attacks, rules which you couldn't change and whatnot.
Never found anything suitable, heard about torshop, but apparently it was a scam.
Which is quite understandable - never trust your private keys to unknown third party, it is just plain stupid.
I think I came up with solution. Well, I didn't invent idea of opensource, but I think I know how to make this thing work.
Let me present Laffka, in its very much alpha stage.
It is written in Flask+python3, and uses* sqli*te as database engine. Doesn't require blockchain downloading, checks transactions online and generates private keys for bitcoin wallet sweeping, thus getting payments for *a t*x price.
Should work clearnet too, I don't see why not. Works excellent and made specially for hidden service purpose.
No binaries whatsoever, everything is in clean and understandable python+html. No surprises, no hidden stuff. Plain opensource. And plain opensource will be released, without tricks.
There are some pypi dependencies, I will list them in documentation upon release.
And release is coming soon. Not yet, but I've decided to draw a little attention, since Laffka accepts and processes payments, albeit on very basic level (no admin console at the moment, lot of functionality still missing)
Please observe alpha version 0.02 in action - http://laffka6wwduoexvb.onion/
make order, or observe existing order - http://laffka6wwduoexvb.onion/pay/mxprSXCVX7WvvADDDVCrKmEhfsvWvznawu
(observe increasing wallet balance upon sending testBitcoins. No blockchain involved.)
It would be greatly appreciated if you'd make order and pay for it. TestNet, not MainNet, so no money involved whatsoever. I require some feedback about project. You can run Electrum in testnet electrum --testnet, and get testBitcoins at some faucet, https://testnet.coinfaucet.eu/en/ for example (there are others)
If link doesn't work, it is ok - means I've took it off, and it will be coming back online bit later. Resource will run continuously when I finish satellite for Laffka (ToDo list is on index at http://laffka6wwduoexvb.onion/)
Thanks for attention.

How Bitcoin have changed my life

So, I know there are many stories out there like mine but I just wanted to thank everyone who have involved on Bitcoin in any way and who have believed in the project and made it come all the way up here and I would like to share my story about how it changed my life.
I have been checking Bitcoin prices since 2011, back then I was a highschool kid and I wasn't aware of what really "blockchain" is. I just read about Bitcoin and the idea was awesome to me and I started talking about it to everyone I know. Back then price was like 100-200 USD if I am not mistaken. I was telling everyone that this is the future's currency and will change everything we know about the "money". Sadly, I was just a kid at age 15 who had no access to any credit card or exchange website. I was just following the Bitcoin price and that was all.
Later, when I start going to college, I was developing my programming skills and learning UNIX, server installations, configurations etc. Back then people were hyped about "Wordpress" and many people wanted to have a website, or a server that can run their websites etc. I was working as a freelancer and was asking people to pay me in Bitcoins. I still remember as it was yesterday, the first time I got paid in Bitcoins was for making a security check on a CentOS server and they paid me 0.3 BTC at the time which worth around 400USD. I have done some other works, small/big whatever gives me money and had around 2.5 BTC at the time. I was just a kid at age 19 and had 2.5 BTC which worth around roughly 800-900 USD. I was so happy to have that type of money which I can use to shop online and it was my own money that I have worked for it. Sadly, I spent all of it to get a new laptop at the summer except 0.6 BTC. Later my friends were planning a trip to another country and my parents didn't gave me any money, so I cashed the last 0.6BTC and got around 600USD and went to the trip with friends, I was happy.
Till here, I was just a guy who was using Bitcoin sometimes for getting payment from projects (I was working for people from other countries so BTC was the easiest way to get paid). Then I stopped working and focused more on my studies, till this August.
August 2017, my father was unemployeed and my mother was also not working because my father was making enough money so she was just writing her blog, travelling around the country and resting after working for 20 years. When my father had to quit his job, we were just left with some small amount of money that would only keep us alive for maximum 4 more months. Then I realized I had to do something and remembered the first thing that made me gain, Bitcoin.
I told my parents about Bitcoin and the blockchain technology, explained them like they are five and my father said "Well, son, this is the only money we have and I believe in you, do whatever you wanna do with it" and I took the money, invested 3/4 of it in Bitcoin and kept the rest for daily expenses. I had like 1.5 BTC at the time.
I have spent hours and hours in front of computer and traded BTC for ALTcoins and made around 4BTC by mid september. I told my parents "Listen, I am going to withdraw the 1.5 BTC and keep the rest, maybe we can make more" and I just saw that BTC was pumping up, so I said "no more trading" (for the people who trades, they know what I mean with it, while trading, you barely sleep, at least in my condition). I kept the rest 2.5 BTC and thanks to God, It reached to 15-16k at the time I sold all of them.
After succesfully doing these trades, reading more about crypto everyday and joining subreddits, facebook groups, I had bunch of "crypto" friends and one day one of them offered me a job at a website as a writer. I took the job and started writing, then a society at a local university called me to "talk" about Bitcoin. After I had interviews with Professors, Economists and many more.
I do not want to give any more details, but now, I bought myself a new phone, a new tablet for daily calculations and keeping track of the things, bought a second hand 2015 model car which is perfect for me. After all these things, I remembered that my grandfather had one wish to go to Makkah (I am a muslim) and do Umrah (a religious trip, mission, whatever you call). I knew this was his last chance to go because he has %70 disability (severe health problems). I called my grandmother and said "You wanna take a trip?" and she was like "Where am I going to go?" and I said "to Makkah" and she cried on the phone and said she just saw a dream and when she woke up, she said to my granddad "I saw it in my dream, but no way we can go there" (they are financially not that good).
After all these things, whoever thinks it's a bubble and whoever thinks Bitcoin is a scam, just read the story and see how it changed a person's life. I was believing in Bitcoin since 2012 and after 5 years of knowing Bitcoin, it finally significantly changed my life and made me the happiest grand-kid ever. I will keep supporting Bitcoin and what it brings to our lives. I have achieved all these things thanks to everyone who believed in Bitcoin and carried it to all the way up here. If you guys wouldn't believe it, now I would be calling friends and trying to borrow some money and my family would be having hard times. Lets show the world what "decentralized" means, lets show them if we stand strong together, we can be stronger than their "centralized" banks and solutions. Together, we can create a better future for our kids. Again, thanks a lot to everyone and sorry for my English.

Blindspot Whitepaper: Specialized Threat Assessment and Protection (STAP) for the Blockchain

BlindSpot™
Stop attacks before ”zero day” and stop the Advanced Persistent Threat (APT)
We live in a dangerous world — our information technology systems face that danger every single day. Hackers are constantly attempting to infiltrate systems, steal information, damage government and corporate reputations, and take control of systems and processes.
Hackers share and use a variety of tools and techniques to gain access to, and
maintain access to, IT systems, including groups and techniques so dangerous
they have their own category - the Advanced Persistent Threat (APT). At the
center of the APT are sophisticated techniques using malware to exploit vulnerabilities in systems. Traditional cyber security technologies use file signatures to locate these tools and hacker malware, but hackers are now actively camouflaging their tools by changing, customizing, and “morphing” them into new files that do not match any known signatures (‘Polymorphic Malware’). This introduces a massive gap in malicious file detection which leaves the enterprise open to exploitation — and it’s just not possible for traditional signature-based systems to keep up. In fact, signature-based anti-virus and anti-malware systems are only around 25% effective today. BlindSpot™ sees through it all, even as the files morph and change in a futile attempt to remain camouflaged.
Digital File Fingerprints
Any File Type, Any Language, Partial Matches, Exact Matches
BlindSpot™, the adaptive security solution from BlindSpot™, can see through the
Polymorphic camouflage used by the worlds most advanced hackers by utilizing
digital file fingerprints and our proprietary adaptive BlindSpot™ ‘brain’ that constantly analyzes the fingerprints of known malicious files and tools to locate partial matches within the files on your systems - servers, laptops, desktops, USB drives, and even mobile devices. BlindSpot™ can cut right through the Polymorphic files, revealing the true hacking tools underneath, even if they are only fragments or pieces of a more complete set of hacking tools and technologies.
Most cyber attacks happen weeks or even months after their initial penetration and access to a network or system, and even the simplest attacks tend to have a fuse that is typically several days. It takes them time to map out a system, probe for the information they want, and obtain or forge credentials with the type of access they need. But from the moment their tools first land on your network and systems, BlindSpot™ sees them. If fact, BlindSpot™ can see them sitting on a newly inserted USB drive even if the files are not copied to your systems. This means BlindSpot™ can identify and alert you to malicious files and potential illicit activities before the attack happens - before zero day!
How does BlindSpot™ work? BlindSpot™ sits on the endpoint and continuously monitors file activity. Digital fingerprints, which can be used to find partial matches of any file type in any language, are reported back where they are kept forever in a temporal repository.
BlindSpot™ looks through all of the digital fingerprints — both those from files on your systems and those in a constantly updated database of known malicious files and hacking tools, to locate and alert you to any indication of hacking, malicious files, or illicit activity. BlindSpot™ is a disruptive technology that can see polymorphic malware and stop attacks before zero day.
Digital File Fingerprints are created from a file or a piece of digital data/information by using advanced mathematics to look at all of the small pieces of data that make up the file to create a very small, unique piece of mathematical data — a digital file fingerprint. Files may be of any file type and in any language - digital fingerprints can find partial and exact matches regardless of what is in the file itself.
Just like with humans, once a fingerprint has been taken, you no longer need the
person to identify them. The fingerprint is enough. Even a partial fingerprint is
enough, and sometimes a smudge will do. Digital fingerprints work on the same
principle. Once BlindSpot™ has taken a digital fingerprint of a file, the file is no longer needed to identify it or to compare it with other files. And because digital fingerprints are tiny, they are easy to store. Even a multi-gigabyte file has a digital fingerprint that is no larger than 10k bytes.
Once you have two sets of digital fingerprints, you can compare them. Because BlindSpot™ starts with full fingerprints of known malicious files, it can identify matching files even when the digital fingerprint is only partially there. And with BlindSpot™’s advanced processing capabilities, file fragments, recovered data from a hard drive, partially downloaded documents, damaged files (both intentional and accidental) and other incomplete file structures can be properly fingerprinted in a way that still allows matches to be found.
Other technologies and software use static signatures, which do not work if any part of a file, regardless of how small, is different from another, or if the file is damaged in any way. BlindSpot™ and digital fingerprints enable partial matching, and can see through the camouflage that has become the industry standard for hackers across the globe. Static signature based solutions simply cannot do this.
Imagine your favorite detective drama on TV. The prosecutor says “This partial
fingerprint was found at the crime scene and the video camera across the
street recorded a perfect image of the person’s face.” The jury deliberates and
compares the picture and fingerprints of the defendant that were taken the day
before. They conclude, because the fingerprint was not all there and was not 100% identical, and because one picture showed a mustache that looked identical but was one millimeter longer than the other picture, that the two people were not identical - and set the criminal free. Well, that show wouldn’t be on TV long because crime would run rampant. Now imagine they had BlindSpot™. Criminals would be caught, the town would be a much safer place, and the show would be on for years to come.
Now imagine your network and systems without BlindSpot™, where traditional
exact match signature software is on your front line of defense. All kinds of
malicious files could walk right through and sit down on your hard drives, just
waiting for hackers to activate them. But you don’t have to imagine what your
systems would be like with BlindSpot™ — instead, simply contact us, get BlindSpot™ in place, and we’ll work with you to show you what’s really on your systems and help you keep those systems safe.
Ensuring System Compliance
Take the guesswork out of compliance assessment
All Government systems go through Certification and Accreditation. BlindSpot™ can help you with malicious code protection, for both security considerations and required compliance. Guidelines found in NIST 800-53 Revisions 3+ Security Requirements for System Integrity, SI-3 Malicious Code Protection, state that malicious code protection mechanisms must be employed at information system entry and exit points, including workstations, notebook computers, and mobile devices, to detect and eradicate malicious code.
BlindSpot™, with its continuous monitoring of the files on your endpoints and its
continuous updating of its known malicious file repository, will provide the
required real-time and full monthly re-scans of your files, will alert your
administrative staff when malicious code is found, will provide reports on
potential malicious files, illicit activity, and follow-up with very short false positive reports. BlindSpot™’s false positive rate is less than 0.01%. BlindSpot™ helps organizations meet the security requirements set forth and ensure compliance.
Intellectual Property Protection
Track sensitive information as it changes and moves around the enterprise
BlindSpot™ uses digital file fingerprints to identify partial and exact matches between files, regardless of file type or language. This ability can be used to track movements of and changes to files on a network of computers.
Government entities and corporations need to addresses the issue of monitoring
documents and files that contain sensitive information intellectual property, and it
is no longer sufficient to simply store them on a secure server and require specific credentials to access the information. People, both unintentionally and sometimes with malicious intent, copy and paste parts of documents, move files to USB drives, and otherwise edit and transfer files in order to get them on to a laptop, share them with a co-worker, or exfiltrate confidential information to outside networks and systems. BlindSpot™ carefully watches all of the files on your network, including what’s going with USB drives. If someone copies part of a file that has sensitive data to another file, BlindSpot™ sees it. Furthermore, BlindSpot™ can alert you when it sees questionable activity with certain documents/files or with specific computers/individuals.
Your sensitive files now have a watchdog that catches both unintentional and
malicious exposure to non-secure systems. Use BlindSpot™ to set up a custom
database of the locations where your sensitive files are stored, and BlindSpot™ will create a set of digital file fingerprints that can be used to track those files across your network and systems. This ensures that an organization can know where its proprietary and sensitive information is 365/7/24, in real-time.
Supervisory Control and Data Acquisition (SCADA) Systems
Supervisory Control and Data Acquisition (SCADA) is a system for remote monitoring and control that operates with coded signals over communication channels (using typically one communication channel per remote station).
SCADA networks contain computers and applications that perform key functions in providing essential services and commodities (e.g. electricity, natural gas, gasoline, water, waste treatment, transportation) to all Americans. They are part of the nation’s critical infrastructure, provide great efficiency, are widely used, and require protection from a variety of cyber threats.
One of the most significant threats is benign files residing on the computers on
the network that morph into tools that hackers can use to gain access to the
network and the equipment it monitors and/or controls. These files might be part
of the operating system (binary files), might be a normal file that includes
scripting, or can even be a general data file moved onto the computer through a
network or a USB drive. By morphing, these files circumvent detection and
countermeasures. This is just one example of how a hacker can compromise and
exploit the system and the worst part is that you will never know until it is too late!
The recent Department of Justice announcement charging Iranian hackers
believed to be tied to the 2013 hacking of a New York dam illustrates this threat
clearly.
Enter BlindSpot™’s BlindSpot™ Adaptive Security — BlindSpot™ monitors all files of all types (any format or language) without the requirement of a translator or human operator. BlindSpot™ can see right through the hacker’s camouflage of
morphing files to quickly identify problems and threats before hackers have the
opportunity to active and use their tools. For U.S. and foreign based systems,
BlindSpot™ is a must have cyber security solution.
The BlindSpot™ team has extensive experience with SCADA systems and critical infrastructure. Our BlindSpot™ solution is critical to the overall security framework of such systems as it was designed to find the morphing, malicious files and associated illicit file activity that can lead to compromise of the integrity, confidentiality and/or availability of the system. Threats loom on both the inside and outside, and the dynamic nature of these systems require continuous, temporal monitoring to stop cyber attacks before they happen.
Stop Ransomware
Identify and remove Ransomware before it encrypts your files
Ransomware attacks are on the rise and affect Fortune 500 companies, Federal
organizations, and consumers. This vicious type of attack affects your user’s ability to get their work done and prevents users from accessing files on a device or network by making the device or network unusable, by encrypting the files your users need to access, and/or by stopping certain applications from running (e.g. the web browser). A ransom is then demanded (an electronic payment of currency or bitcoins) with the promise that your data will be unencrypted and accessible again following the payment.
If the ransom payment is made, there is no guarantee that the data will be
unencrypted or returned to a state of integrity and/or availability. Furthermore,
there is also no guarantee that the people behind the ransom will not re-infect
your systems again with a variant of what was initially used. Payment encourages future attacks because they know you cannot detect it and will pay again next time. Surprisingly, there are only a handful of known ransomware files in use today (e.g. Crowti, Fakebsod). Safeguards exist that use static signatures to find exact matches for these known files, but the moment these files morph or are changed in any way they become undetectable by these solutions. BlindSpot™ digs deeper with digital file fingerprints and can find the new files, enabling you to analyze, quarantine, or delete them before they activate. This pro-active approach can be the difference between a system being protected and a system being made completely unavailable with encrypted data being held hostage for a ransom. The image below is an actual Fakebsod notification message.
BlindSpot™ uses digital file fingerprints to detect the ransomware by looking at
both partial and exact matches and can report the problem before it happens.
Ransomeware of the past attacked your personal computer and today’s variant
attacks the servers — BlindSpot™ can detect both.
Case Study: March 2016 - Two more healthcare networks are hit by ransomware targeting servers. Advice from law enforcement — pay the ransom! (They did). File backups are insufficient. Paying ransoms is costly and only encourages repeat attacks.
BlindSpot™ is the most comprehensive solution available to detect and root out
ransomware. Take charge of the situation and put BlindSpot™ to work continuously monitoring your systems.

BlindSpot Solution Brief
June 29, 2018
POC: Shawn R. Key CEO, President
[[email protected]](mailto:[email protected])
Executive Summary and Estimated Pricing
CYBR’s BlindSpot is an enterprise cyber security solution that pro-actively identifies unknown and known malicious files and circumventive activity on endpoint devices. It is designed to interact with the CYBR Ecosystem and associated Web Portal. Distributed clients serve as the connection to the various BlindSpot server tiers.
BlindSpot identifies Illicit File Activity (IFA) and associated hacker activity via perceptive, industry standard algorithms. BlindSpot identifies exact AND similar files regardless of file type and/or language. This applies to ALL file types (e.g. documents, images, audio and video, carrier, etc.). Currently implemented safeguards and counter measures (such as anti-virus (AV), content filters and malware analysis tools) cannot address polymorphic/adaptive files and emerging threats. This introduces a massive gap in illicit file detection and leaves the enterprise open to exploitation. BlindSpot fills that void.
Additionally, corporations and government entities have a need to address known files and associated activity with regards to content and data management. The uncertainty of Intellectual Property (IP) location and propagation poses significant risk to the organization. The ability to identify the life cycle of a file (origin, source, destination, attributes and proliferation) ensures an organization knows where its proprietary, sensitive and privacy information is 365/24/7, in near real-time.
BlindSpot, is significantly different from solutions in the emerging Specialized Threat Assessment and Protection (STAP) marketplace, as it scales to meet the needs of enterprise organizations and the commercial marketplace. BlindSpot’s proprietary database consists of millions of unique, digital identifiers (hash values) that identify exact AND similar, modified files. This ensures that files existing in their original state or those which have been intentionally modified, do not circumvent detection. Our algorithms ensure near zero false positive return rates. The combinatory effect and the rare expertise of our executives and development thwarts potential competition as BlindSpot is an enterprise solution; not a tool.
The enterprise solution is provide as a license per IP address with associated appliance and/or server hardware requirements.
CYBR BlindSpot Technical Deep Dive
CYBR’s BlindSpot product is currently available as a Software as a Service) (SaaS) deployment blockchain solution and will be available as a full enterprise-install by Q2 2019. In both implementations, end-point agent software monitors the hard drive(s) of a computer or server, analyses any files that change, and reports [multiple] file hashes back to the main system. This enables the main system to effectively monitor which files could be malicious or represent intellectual property on the computers and servers within the customer’s network. By using fuzzy hashing algorithms, the system can detect polymorphic malware and intellectual property that has been partially hidden or obfuscated.
Applications
End-point (client) agent: native to each major OS as a fat client. Currently we have end-point agents for Microsoft Windows-based systems using MS .NET c# 2.0/4.5 and C++, although the c# portion will be replaced with all c++ code to increase scalability, efficiency, and security, in Q1 2016. End-point agents for Mac OS (written in Objective-C) and popular Linux platforms (written in c++) will ship in Q1/Q2 2016. Development work on the CentOS linux agent will begin in December 2015.
The Control Application enables system administrators to configure each end-point agent, the system itself, and to actively monitor and access reports on files that have been identified by the system as problematic or of interest. At this time the Control Application is able to provide configuration and monitoring services but is not yet ready for customer on-site deployment and is therefore only available in a SaaS model.
The middle-tier of the system, the Portal sever, currently runs in MS .NET and is written in c#. This tier will be upgraded to a full c++ implementation to increase scalability, efficiency, and security, in Q1 2016, and will run as a standard web server extension on a Linux platform (CentOS/Apache).
The data-tier of the system currently is running in MS SQL Server 2008/2012 and uses transact-SQL tables, but does not use any stored procedures or transactions. Although this tier is sufficient for scalability through mid to late 2016, a no-SQL version of the data tier will be developed in 2016.
The Crush server (hashing services) currently runs on MS Server 2008/2012, is written in c#/c++ and is a) being ported to run as a (c++) daemon on a standard Linux (CentOS) server, and b) being re-engineered to function as a massively parallel application (c/c++) running on NVIDIA Tesla GPU accelerated systems. The Crush server communicates with the data-tier directly and the C2 server indirectly. Multiple Crush servers can run simultaneously and are horizontally scalable and fault-tolerant.
The C2 (Command and Control) server, written in c# and being moved to c++, communicates with the data-tier directly and the Crush server and Control Application indirectly to provide scheduling, system health and integrity, and prioritization services, as well redirecting jobs to maintain fault tolerance of the back-end server components. Multiple C2 servers can run simultaneously and are horizontally scalable.
Hardware and Network:
The basic architecture of the system has two different stacks of software. First, a typical 3-tier approach isolates data storage from end-point and Control Application access with a middle-man protocol altering Portal server. In the SaaS model, the end-point and Control Application software reside on-site with the customer, and the remaining stack components reside at the SaaS hosting datacenter. The second stack consists of multiple horizontally-scalable server components that run entirely in the backend as daemons and interact primarily through the data area to provide the services that are being marketed and sold to the customers. The two stacks are kept somewhat separate from each other in order to buffer one against the other in times of extreme load and for enhanced security.
Following is a description of each software module in the system and how it relates to the others:
The system has one component for data collection (the end-point agent software, which resides on the desktop computers and servers within a deployed customer site), one component for system administration (the Control Application, which resides on a desktop computer that the customer has access to or that an analyst can access through the SaaS system), and a collection of software processes/daemons and a data storage area that comprise the back-end.
The end-point agent collects data from the end-point computer, passes it to the Portal server, which in turn stores it in the data area.
The C2 server monitors the in-flow of data from the end-points, and tasks the Crush server(s) to analyze the data and compare it to databases of known good, known bad, and watch list files, in an efficient manner.
The C2 server also provides notification to the customer of any problematic or watch-list files following the completion of the Crush server tasks.
The Crush server monitors the data area, and performs batch or real-time processing of data as instructed to by the C2 server.
Technology
CYBR’s BlindSpot software is a commercially available product that combines a small footprint end-point agent with a centralized monitoring and management system to track files and file changes on the end-point using partial-match digital fingerprints rather than rigid full-match-only file signatures. As files and data buffers are created, edited/altered, and moved either through the network or via removable media devices including USB drives, the product uses its unique and proprietary technologies in combination with industry standard technologies to identify and locate both known malware and unknown [polymorphic] malware on end-points that are continuously monitored by the product. Staff is notified, depending on the urgency or type of digital fingerprint identified, through integrations with 3rd party SIEM solutions, email/SMS transmissions, and reports that are available using the central management system. A false positive rate of partial digital fingerprint matching of ~1 in 10-12 means staff will not be bombarded with unnecessary alerts, maintaining staff efficiency.
Overview: Traditional anti-malware products use static file signatures to locate known malware but have no means of detecting unknown malware, CYBR’s product uses digital file fingerprints that can identify both partial file matches as well as full file signature matches and in doing so can locate and identify both known and unknown malware within the deployed enterprise. A combination of industry standard and publicly available algorithms and CYBR’s own proprietary algorithms, trade secrets, methods, optimizations, and intellectual property for which a patent is currently pending (which is owned solely by CYBR) are combined to form a comprehensive anti-malware platform and continuous end-point monitoring product that is completely unique in the marketplace. Through the use of our proprietary algorithms and optimizations, the product has the ability to scale to the enterprise level and can track desktops/servers as well as mobile/phone/tablet/Internet of Things (IoTs) devices.
Project Implementation: The implementation of this product would include both the commercially available BlindSpot product as well as prototypes of integration packages to connect with the on-site Security Information and Event Management (SIEM) and other systems and prototypes of end-point agents running on operating systems that are not yet available in the currently available version of the product. Both the integration and end-point agent prototypes would be based on existing modular code/functionality and would extend functionality past the currently available modules to ensure the full needs and requirements of the project are met. A full version of BlindSpot would be deployed on servers at/on the enterprise site, and prototypes of both SIEM integrations and new end-point agents would be deployed to augment the full production system. Information flow between all areas of the full system and prototypes would be tested and verified with increasing scale to ensure the level of performance required is available prior to the completion of the project.
End-point Agents: Each end-point is installed with native low-profile proprietary agent software that minimizes both its file system footprint and CPU use. The current product has a native end-point available for Microsoft Windows OSs (both desktops/tablets and servers) in production, and has native end-point agents in development/prototype stage for iOS, Android, MacOS, and RHEL/CentOS, with additional popular Linux derivatives to follow. The main job of the end-point agent is to communicate with the OS and monitor the file system for any changes in files that occur. When changes are detected, a digital file fingerprint of the file is taken and reported to the centralized data store, or cached until a later time if the centralized data store is unreachable (e,g, no cell coverage, laptop not connected to internet). The agent normally runs in “stealth-mode” and uses minimal CPU, RAM, and file system footprint so as not to disrupt the end-user’s workflow or impact system performance. Taking a digital fingerprint of a file and reporting it is very fast and thus the main job of the end-point agent is not system resource intensive. The “heavy lifting” is done on the back-end and does not burden the users or the end-point devices. Configuration of each end-point agent is conducted through the centralized management system, and changes in configuration are transmitted to the end-point agent within a few seconds (provided there is network connectivity).
Central Data Store: A collection of databases on the back end store file watch lists, known good and known bad digital file fingerprints (whitelists and blacklists containing digital file fingerprints of known malware), priority lists and configurations, end-point configurations, last-seen lists, and the full temporal accounting of all digital file fingerprints reported by end-point agents. As new threats are identified they are added to the central data store. As files on end-points change or are edited, their new digital fingerprints are added to the central data store as well. As new threats are identified though polymorphic partial matching, they are added to the known bad list as well.
Identification of Known and Unknown Malware: By comparing the databases of digital file fingerprints of known malware and digital file fingerprints of files on end-points, the product’s Crush server(s) use sophisticated algorithms to compare the partial digital file fingerprints, regardless of content of the files themselves. The product looks at the raw data (bytes) in the files when creating the digital file fingerprints and as such all file types/formats/languages are handled. This means that all file types and data in any and all languages can be compared with similar files. Binary DLLs, MS Word documents and spreadsheets (MS Excel, csv, …), JPEG images, Javascript, HTML, Executable files (.exe) — all of these files are handled by the product and known/unknown malware within them can be located using the digital file fingerprints in the centralized data store and Crush server’s analysis.
Scale, System Throughput, and Priority: A single Crush server can serve a small enterprise (100s or 1,000s of end-points), and a horizontally scalable array of Crush servers can be used to provide identification of malware for large enterprises. Similarly, databases in the central data store can be split and maintained/mirrored on several servers or run in a monolithic configuration. This makes the system highly scalable and able to be adapted to enterprises of varying sizes/scales while maintaining a good price/performance ratio. Priority lists can be designated for Crush servers such that high-priority end-points and/or high-priority malware fingerprints can be compared and identified in real-time, and similarly, low-priority lists (e.g. malware fingerprints that have not been seen in months or years) can be run in the evenings or when the system is running below normal load to ensure both immediate analysis of high-priority threats and comprehensive analysis of low-priority threats.
Integration: Several modular integration points within the product enable the straight-forward integration with 3rd party SIEM software and other reporting/management tools and systems. Distinct “notification channels” within the product are used based on the type of threat detected, the priority level of the specific threat detected, the confidence of the match (low percentage match of digital fingerprint vs high), and the location of the match (specific end-point list). Each notification channel has integration points that can be linked in with 3rd party systems so that staff are notified using software and procedures they are already familiar with and trained on (i.e., through a SIEM solution that is already begin monitored by dedicated, trained staff). Prototypes of each specific integration would need to be developed as a part of this project to match/communicate with the exact SIEM (or other) system that is in use at the deployment site in the mannemethod desired. Such a prototype would be developed for the purpose of evaluating the technical interconnectivity between systems to meet the requirements of the deployment, and following the prototype testing period, would be load-tested and stress-tested to ensure it’s performance meets the demands of a highly scalable environment, leading to a mature integration over a period of 3-6 months following the initial prototype period of 1-3 months.
Technology Section Summary: With end-points being continuously monitored by the product, both known and unknown malware threats delivered by the network and removable media will be detected and reported through SIEM system integration and direct email/SMS messages with minimal impact to the end-point (on all major OSs, including desktop and mobile). Centralized management and temporal monitoring of digital fingerprints enables the system to proactively locate and identify malware threats before zero day as well as enabling the staff to conduct their own investigations of systems either in the present or the past for forensic investigations. This makes CYBR’s BlindSpot a complete product that reaches all of the end-point devices to ensure safety and security from all types of malware threats.

Monetize the desktop

Hi,
I want to open a discussion about monetizing I know some of you may consider it evil, but AFAIK CREAM! So my end goal is to put liquidity into the desktop projects that people are actually using in the simplest way possible. What I see in my mind is a three step widgets that will popup maybe in your tray ask you for the sum you wanna give away for project X then 2 more step , means of payment (PayPal, Bitcoin...), Confirmation.
The rationale is that I'm sure there's enough desktop users out there for it to generate substential amount.
Nota: This is about bringing the donate button to the desktop, nothing else.
Now what are the cons?
EDIT : Just before you fucking post about how shady and blood sucking money creature I am read : Just now I'm currently installating a new application for one of my customer on his centos 7 server. I need to install ffmpeg to make it work. Impossible, rpmfusion doesnt have repo yet and the atrpms' dead! What do I do? I have to evaluate either searching the web for an alternative (and evaluate the various random repos) or recompiling myself ( I ran to problems the last time I did ). All that will take more time than it needs. Again some stuffs just need to work!!! Tell me atrpms would have died if it had all the resources!
A task that would have took me 5 mins is gonna take 10 times more, without counting the willpower energy.

Bitcoin node as my first Linux server, it's up!

Got a new desktop. Instead of throwing out my old one, I bought some ECC memory and set it up near the router as a hypervisor. We use them at work and I thought it'd be nice to have my own, but we use Windows more a lot exclusively, and I felt like it's high time I learn how to Linux.
And here's how it went!
su -c 'install -m 0755 -o root -g root -t /uslocal/bin bitcoin-0.10.0/bin/*'
So I guess this means I can use SPV wallets and point them to use my full node to get best of both worlds, right? Either way, this was fun and I learned a lot. I'll be monitoring network utilization to see if I need to throttle it, (I'm on metered internet), but for now, the configuration file is basically just my RPC user and password. I guess that means connections aren't limited?
Just felt like sharing.

[HIRING] one off job to fix a server at a los angeles data center

centos 5, has 2 drives in software raid 1, one drive should be working, but the server does not boot. someone who knows how to get it going, might need to go in, boot from a usb or cd, get it to boot (grub). need a fix, not a re-install! (payment in bitcoin or paypal or amazon card or whatever)
edit: thanks so much to kristopolous who took this issue and had an excellent outcome, restoring the data required from a 2 disk array where one had failed and the other was severely corrupted, setting up the server again with raid1, and verifying it could boot from either disk. he did this on saturday on time and in the agreed budget, and is extremely professional and skilled. i highly recommended him, and it was nice to be able to find a stranger on sysadminjobs to do this.

Questions Answers
This just got cross posted to /sysadmin ; as a fellow research-field oriented sysadmin it gets worse... I too started in the Quake/HL/CS/TF timeframe, but got my degree in CompSci. Have you ever dealt with mice (the mammal kind; I've got worse stories)? Certs: just got my RHCSA this year. I've got the RHCE scheduled for october, and I'm studying for the CCNA, though I use HP switches.
How do you backup desktops / servers? Backups: Luckily, I don't do desktop support. We have another IT group that does that, I'm completely independent from them and I only have to take care of servers (and my own desktop). The physical servers are backed up to tape with Bacula. Our virtual servers are backed up with Veeam. My own desktop is backed up to my NAS share using synctoy (yes, i use windows on my desktop).
How much disk space do you have in one server? One off systems: As in physical servers built by hand? 0. I'm pretty much a Fujitsu shop with a few Dells. I definitely don't have time to be piecing servers together. disk space: only a few TB per server. I think the better answer would be that we have an Isilon X200 cluster that is 140 TB.
one off systems: As in physical servers built by hand? More as in unique software; such as this computer runs the HPLC. I guess in that case I only manage a handful of physical servers and a few VMs that are made for running one special piece of software or analyze data from one piece of scientific equipment. We have many other scientific devices that are attached to PCs that are "community" devices, but I don't have to manage them. and we've got a microscopy group that is separate from me too, with their own machines and devices.
If you are moving to 1gbs are you looking to increase the MTU? I was working on that but had some issues with firewalls for my windows-putty users. First, just to clarify, we're going to 10G from the 1G we have right now. I'm not our main network guy, so I'm not entirely sure but I doubt we'll change the MTU simply because we don't have a remote site so the majority of our traffic is regular internet traffic.
As for our backend network, I do use jumbo frames on a couple VLANs for our storage.
That most important question for any sysadmin...vi or emacs? Vi improved.
Anand Shimpi and Dustin Sklavos had an interesting podcast on the merits of Haswell on the desktop. In short, Dustin echos the enthusiast community's frustration with overclocking headroom decreases from Sandy Bridge Ivy Bridge Haswell. It seems like IPC has gone up but maximum frequency has gone down so the ratio seems almost 1:1. Then there is the issue of the use of TIM and IHS glue cap that caused some to delid their CPUs (and void their warranties). Question 1: What are your thoughts on the overclocking headroom decreases that we've seen? Question 2: Is Intel doing enough to cater to the enthusiast community? Question 3: How do you feel about the delay in the release of Enthusiast parts by Intel (Sandy Bridge-E & Ivy Bridge-E) versus mainstream parts (Sandy, Ivy, and Haswell)? Intel makes good chips and they do keep pushing technology forward, but they will never do overclockers any favors. They will always be doing whatever they can to make money. AMD will also do the same thing. Intel seems to think enthusiast solely means "deep pockets". At the same time, there always seems to be a lot of "the sky is falling" reporting done by many tech journalists. Intel hasn't completely forgotten about overclockers and I don't think they ever will completely let that group disappear. And really, what incentive does Intel have to completely lock out overclockers? Sure, deny us our warranty, we'll go ahead and buy another chip and give you more money. How could you deny that as a company? as for overclocking headroom decreases, one can only hope that means we've got a whole new architecture coming out soon, something like the transition from Pentium 4 to Core.
Do you have a home lab setup to learn/test on? If so, what does it consist of? At home I've got a 1u dell poweredge sitting in a closet which is my main server. I run bageez.us off it which was supposed to be my way of giving back to the community, by running a Linux torrent site. Other than that I've got two htpcs running Debian, a desktop windows machine for gaming/reviewing hardware, and a file server with 8 tb running Debian and KVM with a few Debian VMS.
Do you still have that site going? I tried your link but it didn't work. Looks like I let the SSL cert expire. I'll fix that tomorrow. It works on my end but I think I want to recode a few things and possibly get it to work with other trackers. Right now the torrents will only work with my local tracker.
Need to monitor that ;D. Yeah it's one of those things where I seem to be the only one visiting the site, so why stress about it. I also set up owncloud, but again, i'm the only one that uses it. :(
Do you get to keep the hardware you review? - Do you prefer the black theme or the white theme? Most of the time, yes.
Black. I don't mind the white theme that much tho. edit: he's asking about the forum default skin at overclockers.com/forums
What is your #1 piece of advise for any linux sysadmin? That's a tough one. Do you mean someone looking to become a sysadmin or one that is already a sysadmin?
I guess I didn't specify that did I? I ask the question because I've been doing mostly Windows sysadmin duties for about 2 years and some linux admin stuff. I'm falling in love with Linux and I would love to have a job dedicated to just *nix What advise/suggestions would you give someone that is wanting to make the transition? I think what really got me the best knowledge was forcing myself to use a "less polished" distro as my main rig for a few years. Once you are forced to learn, you'll learn quickly. Picking up an rhcsa book will help too even if you don't plan on taking the exam. Go through it and do the exercises. Install a distro, set it up, then format and do it all over. You can use virtual box for the same result without killing your main rig.
Do you still use FreeBSD? If so, what exactly do you use it for now? No, but I wish I did. I stopped using it because the GPU support in Linux was better on my desktop, and now I work mostly with CentOS, and it would be a lot of work to change 100ish servers over to FreeBSD.
What did you use to train yourself in everything? Just break and fix? Pretty much just the experience of using it daily on my desktop for years. Running gentoo and Slackware really gets you used to doing things for yourself.
Configuration management of choice for those 18 servers? I'm just a jack of all trades sysadmin with a strong focus on problem solving. Are you trying to cure cancer with those 18 nodes or mining bitcoins? I started playing around with puppet but haven't really gotten the hang of it. Right now the cluster is running ROCKS with Grid Engine, and I just use the rocks commands to provision/wipe nodes.
What's the hardest part about getting started with puppet? I think its mostly just finding the time to sit down and have enough time to emerse myself in it.
700+ centos nodes across a few clusters here and I'm loving ansible. Nice. I've heard that ROCKS becomes a bear at scale, but for now it's pretty simple and quick. My plan is to keep adding another 18 nodes every year (one full blade cluster) every year, as long as I can get funding, so I'm keeping my eyes open for other solutions for provisioning. Bright cluster manager is another one I have on my radar.
Computer didn't work for 5 months (it started then after i downloaded skyrim from steam it shut off, then finally worked last month). Put my new graphics card in, then problems ensued. Here: Link to www.reddit.com. 1st step i'd do is remove all nonessential parts from the computer. Leave the cpu and 1 stick of ram. Pull out the graphics card, don't connect any hard drives or cd drives. On the back, connect the monitor to the on board video card and connect the keyboard. Does it power on? Do you get any error messages other than it saying there is no OS? Then power down and connect things one by one until you figure out what part is causing the problem. If you think it's the drivers, you can boot into safe mode (i hope windows 8 still has that, press f8 while booting), then run Driver Sweeper, to remove the graphics drivers. I haven't tried this on windows 8 so i'm not sure if it will run or not. I don't think you need to do a full format and reinstall.
I'll try this tomorrow after work for sure. Do you reddit enough that i could contact you for more advice for help if i run into anything else? (i did contact nvidia team for help, they just told me to delete old drivers without any other help then those words). I don't blame you if you don't want to say you are able to help me with this situation. Humans be humans. Was there a specific reason to go into a cancer research lab? Or was it just a job that came around? No I don't go into photoshopbattles. I pretty much just do what I need for websites and that's it.
How do you like your baked potatoes? (please get into specific detail). It just happened to be the job I found but I love the environment. Much different than a corporate job.
I'm not a fan of baked potatoes but I do love curly fries if that counts for something.
You should really join us in the BAPC IRC channel. I do hang out in the unofficial Overclockers.com irc channel quite a bit. I'll try to drop by.
Do you do any sort of automation for firmware updates? Firmware automation? Nope, and I don't think I'd ever want such a thing. I've been looking at puppet as a way to automatically update software though.
I saw below you guys have some Dell servers, what models and do you use their Lifecycle Controller? We have a couple r610 servers and an equallogic storage box. I haven't heard of this life cycle controller.
What are the specs of your personal rig? Intel i7 3770k @ 4ghz.
Zalman CNPS9900LED cooler.
Patriot ddr3 2x2gb @ 800mhz cas7 (rated for 1200mhz cas9 but I can't boot at that speed anymore for some reason)
MSI Z77A-G41.
ATI Radeon HD 6870.
OCZ Revodrive X2.
How come you have a 3770k but only 4GB of RAM and a 6870? Seems a little overpowered in the CPU category. For benchmarking, mainly. The 3770k was our standard platform for reviews when I bought it. The rest is leftovers from various reviews. We don't get paid, so basically we work for hardware when we write reviews, more or less.
Wait when you review hardware you get stuff? Yes, hardware vendors provide review samples.
Have you ever had an OEM send you equipment different from the consumer version? (Say a factory overclocked version) and claiming it was the standard. Nope. Even if they did, we'd certainly review it as the hardware is, not as they intended it to be.
What's the worst PC loadout you've ever seen? PC load letter? What the f does that mean?
[email protected] JK, doesn't work well on a cluster unfortunately. Unless you have any perls of wisdom on how to make it work on a cluster? Well, it would work just as it does on any other group of computers. I'd have to run one client on each computer and they'd all check back to get their own workloads, so it would really take out the "cluster" usage and turn them just into regular blade servers.
How old are you? Young 30s.
Have you gone to college and completed a bachelor's degree, if not, do you regret it? Yes, BS in Mechanical Engineering.
How did you prove yourself to be worthy of that initial Jr. Sys. Admin job? I listed everything I could think of that I've done that was computesysadmin related. I had administered several web servers over the years, and experimented with many different distributions as my daily driver on my main desktop, so I was very comfortable on the command line and with day to day tasks. I was asked a few 'test' questions on the interview but I think they were more to gauge exactly what i did and didn't have experience with, not so much to make or break me.
Lastly, congrats on doing what you love for a living. Cheers to your future. And thanks. i definitely wake up in the morning with a different attitude than i used to, and that makes a big difference.
Configuration Management / Vagrant / Clouds. I have start playing with configuration management, but haven't gotten anything in production yet. I only provision new VMs every once in a while, and once the computer nodes are up they are pretty stable.
What is your scripting language of choice? I use straight up bash for most things, and python for some. I'm trying to learn more python.
How do you feel about some distros moving away from init.d and going to systemd? I like init.d because it's what I know. Systemd is just a different way of doing things, I'm sure I'll like it once I learn it.
As a OCF Member I have to ask, What is the most extreme cooling you have dealt with?(LN2, Phase Change, Water, D-Ice, etc.) LN2, at the benching party in philly last year. We definitely need to get one of those on schedule again. Also, my work has LN2 and D-ice sitting around but I haven't asked if it's ok for me to play with those yet. One day, i'll ask, and it will be awesome if they say yes. fingers crossed.
So, can I have some of your left over gear? Joking, heh heh... Seriously though, got any gear that's collecting dust? Mostly by the time we're ready to part with gear, it's not worth much and is terribly outdated. Or, it's been burned up by pushing too many volts.
What do you do with the old gear? Do you scrap up a functional computer and donate it to a charity, or just proper e-waste recycling? If it's not on my computer or benching station, it's in my closet. And my wife doesn't like the amount of computer stuff in my closet, so I'm sure I'll start looking for some way to recycle stuff soon.
Where does a young grasshopper starts to learn all of these materials wise one? Well, you could get yourself a RHCSA prep book (linked to the one i have and found useful) and go through all of the exercises. The way I learned was basically to set up my own servers, either physical or virtual, at home, and run them. I think FreeBSD, Gentoo, and Slackware were the most beneficial to me in that they don't really make choices for you, so you have to configure things for yourself which forces you to read the documentation and learn. They all have excellent documentation, btw. If you want to go a step further, linux from scratch will really teach you about the operating system from the ground up.
From there, come up with little projects for yourself. Like making a home NAS, setup NFS and Samba shares, install XBMC on a HTPC and hook it up to your tv to stream movies and music. Setup a webserver and owncloud. Stuff like that.
Sorry I'm late but... how old were you when you first starting tinkering with Linux and such? I'd like to be a sysadmin or similar when I finish school so I figured you were the right person to ask. I was 19 when I first made that half life/counterstrike server. I didn't even know what ssh was and it took a good amount of explaining for me to finally understand. The freebsd documentation is amazing and will walk you through just about everything step by step. To get NAT configured I had to use another how to but setting up that server taught me a ton.
Are you an Nvidia or an AMD guy? It's changed several times over the years. I used to be solely Nvidia because of Linux, but AMD has been stepping up their game and getting their drivers usable, so I currently run all AMD.
How much of a PITA is it for you to be HIPAA compliant? It's not really that tough. Luckily there's only a couple projects going on right now that have special needs above and beyond regular security needs.
What do you use for storage? We have a few Jetstor SANs, a couple Promise RAID boxes, and an Equallogic box as our VMWare backend. But our main mass storage is Isilon X200.
Whoops my bad, meant 1.18 not 1.8 it'd be gone if it was 1.8. sorry. I am using a hyper 212 EVO in the standard push configuration. Well 1.18 is too low for 4.4ghz.
Only 4gigs of ram in your rig ? Yeah...I've got 16 in my work PC for running VMs, and 16 in my VM host at home too. I'll probably buy more soon.
Oh ok, what V would I go to? I was able to initially get 4.4 with 1.18 and 0 whea errors, what V would you recommend? This is my first oc btw. Bump it up one step at a time until you are stable. Be methodical about it. You can check out what values other people are getting on hwbot.org.
Ok Ill do that, thanks man, at what V if the errors dont go away should I stop advancing them? Most likely you will want to stay around 1.6v. I'm not very familiar with that chip specifically so I'd check hwbot to see what other people have posted and go by that. Obviously remember that not all chips are the same, so you can't expect to get exactly what other people get.
1.6, that seems a bit high for my 212 EVO, a few days ago I did have it at 1.18 without any WHEA 20 errors. That's why I'm saying take it slow, one step at a time.
What do you think of this quote by Richard J. Schwartz? "The impact of nanotechnology is expected to exceed the impact the electronics revolution has had on our lives." Sounds good to me. I can't wait to see what comes next.
Actually nodes, or are some of them VMs? Physical blade servers as nodes. with 144 GB ram each.
Zfsonlinux in use? No I haven't used zfs at all.
Hey... You're pretty cool. Thanks. You're not too bad yourself.
The answer should be ''i wish i could say the same to you'' I'm not like that.
Just how big is your hpc. Only 18 nodes :/ but its more what I do with it...
How'd you get your nickname. Back when I played CS in the dorm freshman year of college, I used to get killed all the time. So I started calling myself "jack splat", as a play on the nursery rhyme (jack sprat), then shortened it to 'splat' on most of the websites I signed up for.
Describe a SHTF moment at your work place. I can imagine it must be highly stressful being the sole responsible person to keep all that gear running. I definitely have a few and luckily they aren't that bad. One of my first few months, I decided to connect this wireless ap to the network to test it out one morning. As I was being awesome managing the cable to make it look clean, one of the security guards came into the server room and said they had no internet. I looked at our switches and they were all lit up solid. By hooking up the ap, which had spanning tree turned on, I took down the network of the entire building.
Ouch...that's definitely a SHTF moment. glad you came out unscathed. Luckily, all I had to do was unplug it and everything went back to normal. I then set up a spare switch at my desk and played with it before figuring out that STP needed to be disabled on the AP. Now it's been running for over a year without incident.
Would you rather fight 100 duck sized horses or 1 horse sized duck? I'd go for the horse sized duck. Seems like more of a challenge.
U mad? Nah, I'm feeling pretty good today.

Ethereum Wallet Linux Install How to Setup a Bitcoin Wallet- Bitcoin tutorial - How to get a wallet and your first bit coins How To Install Electrum On Linux How to install Bitcoin Core Wallet and send Bitcoins How to Install & Use bitcoin wallet tutorial for beginners!

It’s fairly simple to run a full bitcoin node on CentOS 7, if you want to compile one from source. Alternatively, you can run the bitcoind daemon in a Docker container too. These steps will get your server ready to compile Bitcoin from source. So I prefer to stick with the precise version that bitcoin.org uses in the binary builds they distribute. Happens to be same version CentOS 7 has now but that may not always be the case. It isn’t with CentOS 6. Anyway if anyone one this list has interest, figured I’d share the spec file. Adding SELinux to the server package I will work on. Where can I find instructions, or what are the exact steps to install Bitcoin Core on a CentOs Server? Stack Exchange Network Stack Exchange network consists of 177 Q&A communities including Stack Overflow , the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Enable snaps on CentOS and install bitcoin-core. Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions. The following instructions show you how to configure, compile, and install Bitcoin 0.9.4 on CentOS 7. Update Your Operating System Packages The first step is to always make sure your operating system and all of it's packages are up-to-date.
