Hi, I have a spare 1GB server and I would like to help the network by running Bitcoin but seems that is not easy to setup in CentOS.
I need some updated info about running bitcoind easily.
Thanks
submitted by 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.

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.

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.

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.
submitted by 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. 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. By default, CentOS 8 server with graphical user interface will be installed. But, if you want to install CentOS 8 headless server, then click on Software Selection. NOTE: I will install CentOS 8 headless server in this article. Now, select Server and click on Done. Now, click on Network & Host Name. Type in a host name and click on Apply. 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. 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.
