An Analyst’s Environment

This week we had a chance to work with an analyst who is new to our environment. The conversation revealed some things we find pedestrian that are exciting to a new person, so we’re going to detail them.

Alerts

Many people use Google’s Alerts, but far fewer are familiar with the service Talkwalker offers. This company offers social media observation tools and their free alerts service seems to be a way to gather cognitive excess, to learn what things might matter to actual humans. These alerts arrive as email, or as an RSS feed, which is a very valuable format.

Feed Reading

Google Reader used to be a good feed reader, but it was canceled some years ago. Alternatives today include Feedly and Inoreader. The first is considered the best for day to day reading activity, while Inoreader gets high marks for archival and automation. The paid version, just $49 per year, will comfortably handle hundreds of feeds, including the RSS output from the above mentioned Talkwalker.

Content Preservation

Talkwalker Alerts never sleep, Inoreader provides all sorts of automation, but how does one preserve some specific aspect of the overall take? We like Hunch.ly for faithful capture. This $129 tool is a Chrome extension that faithfully saves every page visited, it offers ‘selectors’, text strings that are standing queries in an ‘investigation’, which can be exported as a single zip file, which another user can then import. That is an amazingly powerful capability for small groups, who are otherwise typically trying to synchronize with an incomplete, error filled manual process.

Link Analysis

Alerting, feed tracking, and content preservation are important, but the Hunch.ly investigation is the right quantum of information for an individual or a small group. Larger bodies of information where linkages matter are best handled with Maltego Community Edition, which is free. There are transforms (queries) that will pull information from a Hunch.ly case, but the volume of information returned exceeds the CE version’s twelve item limit.

Maltego Classic is $1,000 with a $499 annual maintenance fee. This is well worth the cost for serious investigation work, particularly when there is a need to live share data among multiple analysts.

Costs Of Doing Business

We are extremely fond of FOSS tools, but there are some specialized tasks where it simply makes no sense to try to “roll your own”. This $1,200 kit of tools is a force multiplier for any investigator, dramatically enhancing accuracy and productivity.

Impressive Performance With Elastic 6.5.1 & Search Guard

After Implementing Search Guard ten days ago I was finally pushed into using Elasticsearch 6. Having noticed that 6.5.0 was out I decided to wait until Search Guard, which seems to lag about a week behind, managed to get their update done.

The 6.5.0 release proved terribly buggy, but now here we are with 6.5.1, running tests in A Small Development Environment, and the results are impressive. The combination of this code and an upgrade from Ubuntu 16.04 to 18.04 has made the little test machine, which we refer to as ‘hotpot‘, as speedy as our three node VPS based cluster.

Perflog Dashboard

This is a solid long term average of fully collecting over eleven accounts per minute, but the curious thing is that it’s not obvious what resource is limiting throughput. Ram utilization eventually ratcheted up to 80% but the CPU load average has been not more than 20% the whole time.

Utilization Dashboard
Utilization Dashboard

There is still a long learning curve ahead, but what I think I see here is that an elderly four core i7, if it has a properly tuned zpool disk subsystem, will be able to support a group of eight users in constant collection mode.

Kimsufi Servers
Kimsufi Servers

And that makes this page of Kimsufi Servers intriguing.  The KS-9 looks to be the sweet spot, due to the presence of SSDs instead of spindles. If our monthly hardware is $21 that puts us in a place where maybe a $99/month small team setup makes sense to offer.

There is much to be done with Search Guard before this can happen, but hopefully we’ll be ready at the start of 2019.

Implementing Search Guard

Our conversion to Elasticsearch began almost a year ago. Aided by their marvelous O’Reilly book, Elasticsearch: The Definitive Guide, we grew comfortable with the system, exploring Timesketch and implementing Wazuh for our internal monitoring. Our concerns here were the same issue we faced during prior Splunk adventures – how do we fund the annual cost of an enterprise license?

Search Guard solves the explicit cost question and it does a good job on the implicit barrier to entry problem. What you see below is the contents of the Search Guard tab on our prototype system, which more or less installed itself with single command.

Search Guard
Search Guard

The initial experience was so smooth we decided to implement Search Guard on our cluster, which has been a learning experience. The system requires Elasticsearch 6.x, but we have clung to the familiar environment of the 5.6 version of the system. The switch required a solid day of fiddling with Bash scripts and Python code in order to make everything work with the newest Elasticsearch, and then the cluster upgrade was not nearly so straightforward.

The self-installing demo reuses a PKI setup. That’s great for lowering the barrier to entry for initial experiments, but there is no way that can be used on a publicly accessible system. Having done a bit of PKI here and there, the instructions and scripts they offer are fairly smooth.

The troubles began when we moved from Elasticsearch 5.6.13 to 6.4.3. A stumble on our part during Search Guard install left us with a system that was stuck tight. Their install procedure could not continue from the state we had put the system into, while our command line tools and system knowledge were insufficient to back out of the partially completed process.

Resolving that took the better part of a day, but it proved beneficial in the end, as their voluminous documentation did not address the specific problem, but it did offer many pointers. Think: six months troubleshooting experience in an afternoon, and questions posted to their Google Group yielded authoritative answers within hours.

There are six weeks left in 2018 and during this time we are going to accomplish the following:

  • Finish converting botnetsu.press to Search Guard Enterprise
  • Index Twitter, RSS data, and one chat service for the team
  • Explore roles and permissions against real world considerations
  • Create a public facing dashboard for botnetsu.press
  • Implement Search Guard for a Wazuh system

Best of all, Search Guard offers a gratis Enterprise license to non-profits. We have applied for this for both botnetsu.press here in the U.S., as well as a similar effort in the U.K. Given just a bit of luck, we’ll have two teams active in the field by the end of first quarter, and maybe some of the commercial opportunities we are pursuing will come to fruition as well.

 

The Shape Of The Internet

One of the perennial problems in this field is the antiquated notion of jurisdiction, as well as increasing pressure on Westphalian Sovereignty. JP and I touched on this during our November 5th appearance on The View Up Here.  The topic is complex and visual, so this post offers some images to back up the audio there.

Regional Internet Registries

Regional Internet Registries
Regional Internet Registries

The top level administrative domains for the network layer of the internet are the five Regional Internet Registries. These entities were originally responsible for blocks of 32 bit IPv4 addresses and 16 bit Autonomous System numbers. Later we added 128 bit IPv6 addresses and 32 bit Autonomous System numbers as the original numbers were being exhausted.

When you plug your home firewall into your cable modem it receives an IP address from your service provider and a default route. That outside IP is globally unique, like a phone number, and the default route is where any non-local traffic is sent.

Did you ever stop to wonder where your cable modem provider gets their internet service? The answer is that there is no ‘default route’ for the world, they connect at various exchange points, and they share traffic there. The ‘default route’ for the internet is a dynamic set of not quite 700,000 blocks of IP addresses, known as prefixes, which originate from 59,000 Autonomous Systems.

The Autonomous System can be though of as being similar to an telephone system country code. It indicates from a high level where a specific IP address prefix is located. The prefix can be thought of as an area code or city code, it’s a more specific location within the give Autonomous System.

There isn’t a neat global map for this stuff, but if you’re trying to make a picture, imagine a large bunch of grapes. The ones on the outside of the bunch are the hosting companies and smaller ISPs, who only touch a couple neighbors. The ones in the middle of the bunch touch many neighbors and are similar in position to the big global data carriers.

Domain Name Service

Once a new ISP has circuits from two or more upstream providers they can apply for an Autonomous System number and ask for IP prefixes. Those prefixes used to come straight from the RIRs, but any more you have to be a large provider to do that. Most are issued to smaller service providers by the large ones, but the net effect is the same.

Having addresses is just a start, the next step is finding interesting things to do. This requires the internet’s phone book – the Domain Name System. This is how we map names, like netwarsystem.com, to an IP address, like 95.173.136.70. There is also a reverse DNS domain that is meant to associate IP addresses with names. If you try to check that IP I just mentioned it’ll fail, which is a bit funny, as that’s not us, that’s kremlin[.]ru.

Domain Name Registrars & Root DNS Servers

How do you get a DNS name to use in the first place? Generally speaking, you have to pay a Registrar a fee for your domain name, there is some configuration done regarding your Start Of Authority, which is a fancy way of saying which name servers are responsible for your domain, then this is pushed to the DNS Root Servers.

There are nominally thirteen root servers. That doesn’t mean thirteen computers, it means there are twelve different organizations manage them (Verisign handles two), and their addresses are ‘anycast’, which means they originate from multiple locations, while the actual systems themselves are hidden from direct access. This is sort of a CDN for DNS data, and it exists due to endless attacks that are directed at these systems.

Verisign’s two systems are in datacenters on every continent and have over a hundred staff involved in their ongoing operation.

Layers Of Protection

And then things start to get fuzzy, because people who are in conflict will protect both their servers and their access.

Our web server is behind the Cloudflare Content Distribution Network. There are other CDNs out there and they exist to accelerate content as well as protect origin servers from attack. We like this service because it keeps our actual systems secret. This would be one component of that Adversary Resistant Hosting that we don’t otherwise discuss here.

When accessing the internet it is wise to conceal one’s point of origin if there may be someone looking back. This is Adversary Resistant Networking, which is done with Virtual Private Networks, the Tor anonymizing network, misattribution services like Ntrepid, and other methods that require some degree of skill to operate.

Peeling The Onion

Once you understand how all the pieces fit together there are still complexity and temporal issues.

Networked machines can generate enormous amounts of data. We previously used Splunk and recently shifted to Elasticsearch, both of which are capable of handling tens of millions of datapoints per day, even on the limited hardware we have available to us. Both systems permit time slicing of data as well as many other ways to abstract and summarize.

Data visualization can permit one to see relationships that are impenetrable to a manual examination. We use Paterva‘s Maltego for some of this sort of work and we reach for Gephi when there are larger volumes to handle.

Some of the most potent tools in our arsenal are RiskIQ and Farsight. These services collect passive DNS resolution data, showing bindings between names and IP addresses when they were active. RiskIQ collects time series domain name registration data. We can examine SSL certificates, trackers from various services, and many other aspects of hosting in order to accurately attribute activity.

Conclusion

The world benefits greatly from citizen journalists who dig into all sorts of things. This is less than helpful when it comes to complex infrastructure problems. Some specific issues that have arisen:

  • People who are not well versed in the technologies used can manage to sound credible to the layman. There have been numerous instances where conspiracy theorists have made comical attribution errors, in particular geolocation data for IPs being used to assert correlations where none exists.
  • There is a temporal component that arises when facing any opponent with even a bit of tradecraft and freely available tools don’t typically address that, so would-be investigators are left piecing things together, often without all of the necessary information.
  • Free access to quality tools like Maltego and RiskIQ are both intentionally limited. RiskIQ in particular cases problems in the hands of the uninitiated – a domain hosted on a Cloudflare IP will have thousands of fellows, but the free system will only show a handful. There have been many instances of people making inferences based on that limited data that have no connection to objective reality.

We do not have a y’all come policy in this area, we specifically seek out those who have the requisite skills to do proper analysis, who know when they are out on a limb. When we do find such an individual who has a legitimate question, we can bring a great deal of analytical power to bear.

That specific scenario happened today, which triggered the authoring of this article. We may never be able to make the details public, but an important thing happened earlier, and the world is hopefully a little safer for it.

 

Domestic Extremist? Or Something Else?

What does this site say to you at first glance?

patrioticfreedomfighter[.]com
patrioticfreedomfighter[.]com
This is one of nearly two dozen sites pushing fringe right wing views that are all associated with Mark Edward Baker, as detailed in this story by McClatchy. When I first heard of this the initial thought was that something so slippery could be a foreign influence operation. I came to a much different conclusion, but it took many hours of digging.

Here are the full list of domains involved:

The physical plant for this is a circus – 434 unique IP addresses and they all seem to be tied to the operation.

A simpler exam of the SOA for each domain yielded a deeper clue in the form of the [email protected] address used for registration. It’s connected to another cluster of domains.

gomarkb@gmail.com domains
[email protected] domains

We are not going to revisit the merry chase this guy provides – fire up hunch.ly and go at it. He uses the alias Mark Bentley, be on the lookout for LOP, which is short of League of Power, and his wife Jennifer is a signatory on some of the paperwork. He has at least half a dozen PO boxes in Florida and a similar setup in Reno, Nevada, which appears to he his origin. Once I was sure I had a real name, I was more interested in what his business model is and if there were any foreign ties.

If you poke around for League of Power you’ll find complaints about his $27 scam work from home DVD. This guy’s ideology is getting other people’s money and providing little to nothing in return. This is pretty common to see on both sides of the aisle – grifters working the earnest, but naive masses. This guy clearly focuses on the right – different skills are needed to run a similar game against the left.

Here is the one image that more or less sums up what he is doing:

Mailgun Usage
Mailgun Usage

You would have to be in the business of examining attribution resistant hosting to notice this, but it was like a flashing neon sign for me. Domains that don’t want to be traced typically have no email handling at all. This guy’s business model is list building, which he’ll use for maybe some political stuff, but it will be an ongoing bulk mail target after the election.

 

What about foreign influence being behind this? The article mentions that conservativezone[.]com[.]com had been used. That’s a spearphishing move. It resolves to these geniuses:

conservativezone[.]com[.]com
conservativezone[.]com[.]com
What is AS206349? A dinky autonomous system in Bulgaria with a history of IP address hijacking. Baker got some service from these guys, but it wasn’t anything he wanted to receive. The may have noticed he was gathering lists of the easily duped and decided this would be a good phishing hole for them.

 

People who are way into the bipolar politics in the U.S. tend to judge things as either on their side, or the opposition. There are nuances on that spectrum that get ignored, foreign influence, weird cyberstalker types, and just outright fraud, like we’re seeing here. Don’t jump to sticking a red or blue label on something until you’ve had a good chance to inspect it and conjure up some alternate theories.

Russian Infrastructure, Domestic Threats

Let’s take a look at a curious thing in RiskIQ – the October 22nd registration for the 0hour1[.]com domain.

0HOUR1 Registration
0HOUR1 Registration

The nameservers at westcall[.]ru are part of a large ISP in St. Petersburg. The registrant’s trail is an intentional mess, but lets see what we can find on Brian Durant. It’s helpful to know his birth name –  Fiore DiPietrantonio.

Durant came to my attention because his crew are bothering a CVE researcher I know, and threatening a man in Brooklyn that they mistakenly identified as them. There is a decent Threadreader on Durant from @trebillion that provided me a starting point.

Achtung! If you choose to pursue this, you must turn your OSINT tradecraft up to eleven. The name change is an attempt to leave behind a shady past, there is intentional deception at work prior to the politics, and don’t chase after a pretty face on a largely empty persona.

As a sign of how much of a hassle this backtrail was, take a look at my hunch.ly case for it. And this is the second one – the first draft had so much crud in it I found it easier to just start over and revisit the stuff I confirmed.

Three Domains & Hosting
Three Domains & Hosting

I got distracted writing this and spent half an hour playing with the RiskIQ response to the Maltego Domain Analysis transform. GoDaddy is a terrible swamp that typically reveals nothing, so I collapsed it to a point to better see the other things. The westcall[.]ru nameserver mistake only showed in the registration, they caught it before it started turning up in  passive DNS. So what are these three other things we see?

192.169.82.86 is part of The Swamp – the tiny allocations in 192.0.0.0/7 that were handed out for free back in the eighties. RiskIQ shows over 9,000 names for it, Maltego finds 552, ARIN says it’s a point to point link from Limestone Networks to a customer. It’s been passed around for thirty years or more and I don’t think it tells us much. The reverse lookup is the last one someone carded to enter and those don’t seem to matter much on shared servers. Make a mental note to come back, only if all else fails.

86.106.93.230 is a European address, you can tell just by the leading octet, and with a little poking we find it’s in AS44901 – BelCloud Hosting, but it’s listed with over 10,000 other names.

What about 149.56.202.49? Looking at the times it was active we find that it had the system to itself, running what looks to be WordPress under cPanel.

This is turning into a common theme – people trying to do their own hosting and then giving up after a couple days.  The DNS tab provided another interesting clue that I just noticed as I was drafting this article.

And what’s going on here? Every time I look at this thing I find another eastern European/Russian link.

So … I thought this was going to be a declaration and instead it’s a problem statement – there is more digging to do here. But there is one piece of digging that is done – the ID of Brian Durant’s associate who threatened me when I first started probing is within easy reach. Check the DM that @NetwarSystem received on October 17th and the menacing voicemail from October 27th.

This “very reasonable dude” is @MistaBRONCO, which has been a stable alias for him for at least six years. It was on his Flickr account, where a close inspection of cat photos turned up this gem. Handsome boy, isn’t he?

BRONCO, International Cat Of Mystery
BRONCO, International Cat Of Mystery

So our internet tough guy who cleverly pressed *69 before he left me a message on a Google Voice number that hasn’t a phone attached to it in five years is laid low by the ol’ surname & multiple phone numbers on a pet’s nametag. Amateur hour here – stable name, personal details all over the place. This is all recorded in hunch.ly and the good bits of the YouTube channel that put the voice with this cat are safe, too.

So I’ve got a voice threat, another guy that this genius misidentified as Ca1m has received threats, the source lives on Long Island, the target is in Brooklyn. Since these are both covered by the NYC FBI field office and I was pointedly told to “come correct”, I had the following exchange with the counter-terrorism SA in that office, whom I’ve known since Occupy days.

Alerting Agent Smith

That’s as correct as I can play it in the wee hours of a Friday right before a midterm in which Russian influence is certainly still a problem.

How’d I do?

 

SocialLinks: An Actual Investigation

We have a special treat today, an actual investigation and preservation exercise on a Russian company we have had our eye on for the last year. First, to understand why today is their lucky day, peruse this New York Times article:

Here’s the lede from the article for those who refuse to click through:

On the same day Facebook announced that it had carried out its biggest purge yet of American accounts peddling disinformation, the company quietly made another revelation: It had removed 66 accounts, pages and apps linked to Russian firms that build facial recognition software for the Russian government.

This is a good step, but it isn’t the only housecleaning needed.

Available OSINT

If you open the current Maltego client you will see the Transform Hub, a listing of all service providers you can integrate. This is what you see this morning in the left hand column if you open the application on a 4k monitor. Note what is first and what is last.

SocialLinks Offerings In Maltego
SocialLinks Offerings In Maltego Transform Hub

I am the admin for the Maltego Group on LinkedIn. This is a screen shot I collected this morning. Implicit in this is a violation of Facebook terms of service, the source is SocialLinks CEO Alexandr Aleexev.

The company’s YouTube page has a variety of other demonstrations that indicate similar practices on other social media platforms. I snagged a screen shot from the video, which shows what they were doing a year ago.

SocialLinks Social Media Platforms
SocialLinks Social Media Platforms

This alone is enough to set off alarm bells given the current climate. We know a bit more about this company, because I assumed their appearance on the Transform Hub meant they were a quality provider. I spent $130 for a month of service in November of 2017, setting off six weeks of curious encounters, both with them, and disinterested counter-intelligence investigators on three continents.

Our Encounter

Needing to capture some Instagram content for a civil case, I grew weary of chasing threads after I got acquainted with the players, so I went looking for an automation solution that would capture their social network. I had an Instagram account to use from one of the parties to the case, but I assumed it would be burned the minute any evidence from it showed in a filing.

What I received just plain didn’t work. Not with Instagram, not with my personal LinkedIn network, not with Github, which should be fairly open.

SocialLinks Troubles
SocialLinks Troubles

This went on for a while, at first with me sharing details of DNS resolution issues for their servers and other stuff that seemed like normal troubleshooting. When I went to LinkedIn and made contact with CEO Alexandr Alexeev, I was immediately suspicious given his Moscow location.

We had an initial conversation on LinkedIn, below is an example of how things started. We agreed to meet on Wire, and there I was asked about VPNs, provisioning proxies in the U.S., and other means to circumvent access restrictions. I played along, thinking that some counter-intel attention might be forthcoming.

Counter-intelligence Failures

I felt there was plenty of reason for attention on this situation, but after a month of asking for attention, no fewer than three governments who should have been interested all struck out without so much as a single swing.

  • United States – target of Russian election interference.
  • United Kingdom – target of Russia referendum interference.
  • South Africa – home of Maltego maker Paterva.

I’m not saying that I typed this all into IC3, pressed ‘send’, and crossed my fingers. I had conversations with two people in the U.S. IC community, I talked to James Patrick at Liberty STRATCOM, and I have an associate who has a personal relationship with a brigadier in Hawks, South Africa’s Directorate for Priority Crime Investigation.

There are two ways to interpret this – either the system has already noticed and is working the problem, or the system is utterly overloaded and we are on our own. The fact that I got no response from any of the three countries made me think it was the latter. Having covered my own position, I sat back to see what happened next.

Further Cause To Act

Two months ago I met up with someone who had experiences with Social Links that were very similar to mine. I had already come to believe  I was dealing with someone trying to “handle” me, albeit clumsily, and probably seeking advice from someone else in the process. Talking to this other party hardened that impression. That’s all I am going to say about this.

Removal

As a last ditch effort, I reached out to an FBI Special Agent I know last week. They had the weekend to think it over, Monday to act, and the NYT article is the last piece of stimulus I need.  I just removed Alexeev from the LinkedIn Maltego Group and later today I am going to remove his posts, after announcing why he was removed.

Alexandr Alexeev Removal

Preservation & Publication

The particulars of what happened are important so I set out to preserve the details. Here are the steps I took:

  • Started Hunch.ly, preserved forty pages, both public and private. This application preserves content in an admissible fashion.
  • Launched MediaHuman’s YouTube Downloader  just in case they or YouTube decide to wipe their channel.
  • Preserved the @_SocialLinks_ Twitter account for further analysis using both Maltego and our internal tools.
  • Wrapped up the exported Hunch.ly casefile, the Maltego graphs, and the videos, transferred it to a person who will hand carry it to a former U.S. Attorney we employ for certain sorts of touchy situations.

That last bit is just for my protection, given that our President and Attorney General both appear to be compromised by the Russian government. I will not be subject to a raid that deprives me of exculpatory evidence, followed by a politically motivated prosecution.

Conclusion

In the absence of any response from the agencies that ought to handle problems like this, I guess we are in charge for the moment. If you’ve had similar troubles with this company, I advise you to back up everything, transfer it to legal counsel so that it is protected from seizure by attorney client privilege, then reach out to your local FBI field office.

I have shared the particulars with a couple reporters, too. If you have similar experiences and wouldn’t mind being interviewed on this, feel free to contact me.

Profound Tradecraft Failure: Wohl v. Mueller

Manchild scammer extraordinaire @JacobAWohl has been the center of a vortex of public attention for the last day or so, but it isn’t working out quite as he had envisioned. The scheme as revealed thus far has involved:

  • A front agency, Surefire Intelligence, with a claimed global footprint, based entirely on virtual office spaces.
  • A staff, several of whom had stock photos from A list celebrities, but only two of which had any contacts.
  • A second front agency, Atrium Private Intelligence, with a domain registered after Surefire’s, apparently existing to provide depth to the legend for the first agency.
  • Domains registered by proxy, but configured with a web site construction kit that included Wohl’s personal email in the SOA (Start Of Authority) for the domain.
  • Google Voice phone numbers, one of which Wohl validated with a real number belonging to his mother.

We are obviously publishing Analytical Tradecraft here, but Field Operations Tradecraft is another story entirely. One can not learn to tease things apart without gaining some sense of what not to do, but providing the affirmative defenses is a step we are not willing to take, at least not in the open. When we address Adversary Resistant Computing and Adversary Resistant Networking, the aim is to keep you safe in your pursuits. You will notice there is no Adversary Resistant Hosting category.

That being said, the failures can be summarized as “youthful enthusiasm”. Hertz will not rent to anyone under twenty five, our society’s firmest recognition that the neurological stuff that starts with the teen years doesn’t at high school graduation. Whatever role Jack Burkman and Jim Hoft played in this scheme, the execution was left in the hands of a lad that won’t be able to drink legally for another six weeks.

The primary reason you are reading this site (we think) is not for our slick production quality or our mastery of algorithms. You are here because we have been there. We try to keep what we do simple, rugged, and recoverable, because we are used to having too few resources, too many tasks, and not nearly enough time.

 

A Small Development Environment

The early version of the Netwar System ran with a handful of Twitter accounts and a flat file system. Today we use a 64 gig Xeon with 48 Twitter accounts for internal studies and a trio of 16 gig VPSes for botnetsu.press, our semi-public service. The requirements for an R&D system exceed a virtual machine, unless you’ve got a Xeon grade desktop.

We happen to have a Dell m4600 laptop and eight unallocated Twitter accounts, so this has been built out as an R&D environment. The system has a four core i7, 16 gig of ram, and in addition to the system volume there is a 60 gig msata SSD and a 500 gig spindle in the disk carrier that fits in the CD/DVD bay. This is essentially a miniature of our larger Xeon system.

Disk performance has always been our problem with Elasticsearch, so the msata drive was split into cache and log space for a 465G ZFS partition.

Disk /dev/sdb: 55.9 G

/dev/sdb1 28G

/dev/sdb2 27.9G

Next, examine the configurations for Elasticsearch and Kibana in /etc. You’ll want to ensure there is more than the default 2 gig for the JVM and modify the Kibana config so you can reach port 5601 from elsewhere.

 

We have come to the point where we must release configuration advice and some Python code in order for others to learn to use the system. We’re going to trust that the requisite system integration capabilities, analytical tradecraft, and team management skills are going to limit the number of players who can actually do this. There isn’t a specific Github repository for this just yet, but there will be in the coming days.

There has been a gap in the social network analysis world since @ladamic stopped offering her excellent class via Coursera. I received my copy of Complex Network Analysis in Python earlier today, devoured the first five chapters, and I am pleased to report this book is a quality alternative to the class.

The book presumes you have enough Python to load stuff with pip and some pre-existing motivation to explore networks. Some key things to know:

  • The features and performance considerations of four Python network analysis modules are explained in detail; invaluable for those who are trying to scale up their efforts.
  • The visualization package Gephi is introduced in a very accessible fashion and advice regarding how to move data between it and your Python scripts is clear and simple.
  • There are a variety of real world examples included

The thing that is missing is Twitter – which is mentioned just once in passing on page 63. This seems like a good opening – the Complex Network Analysis Github repository is going to contain the Twitter related code we produce as we work through the examples in this text.
