Confirmed! The NSA hunt for Snowden led to the ruin of Lavabit

Submitted by: Slydder

The long suspected grounds for Levisons’ decision to shutdown Lavabit have now been, inadvertently, verified by the NSA.

Rather than comply with a Court order to provide the NSA access to all Lavabit communications, Levison decided to close up shop in the summer of 2013.

In an ineptly executed release of documents in the federal PACER database this month, the NSA left Snowdens mail address, ‘Ed_snowden@lavabit.com’, unredacted for the world to see.

Recently one of the RedHat maintainers of GlusterFS requested that I do a quick writeup of the new Diamond collector that I wrote as a way of introducing metrics gathering for GlusterFS using Diamond to feed InfluxDB and ultimately Grafana.

Getting the Job Done with Let’s Encrypt

Submitted by: Slydder

The Let’s Encrypt project (or movement if you wish), backed by Facebook, Cisco, Akamai, Mozilla, EFF and many more; is now in open beta. Since closed beta started I have been hearing a lot of trash talking from people that are not happy with certain aspects of the implementation and requirements.

Fix for HA Clustering Froxlor

Submitted by: Slydder

One of the requirements of clustering web servers is that the loadbalancers in front can count on the fact that all the content nodes are on the same sheet of music. Therefore, it is not a bad idea that all content and configurations are the same. This cannot happen when the web server configuration is locked to a single node (via IP address) and cannot be used on any other node.

Short list of must have tools

Submitted by: Slydder

Over the course of ones carrier as a System or Network Administrator one will encounter a quite a few utilities to “help” in the excution of ones work. A large majority of those tools are either flawed in logic or execution, incomplete or just generally useless. However, every once in a while a tool will surface that fits just perfectly in just about every admins toolbox. Here is a list (in alphabetical order) of some of my favorites. If you have any that should be listed just let me know.

PHP-FPM Processor Load

Submitted by: Slydder

I run just about everything in Proxmox/OpenVZ containers. Recently I noticed after doing a fresh install of PHP-FPM that the pools for PHP-FPM were eating up a LOT of CPU time. That PHP-FPM can eat up a processor is nothing new. However, the pools were doing absolutely nothing. They were just idling there and were causing ca. 40% load on the processor.

Tomcat 6 with logrotate

Submitted by: Slydder

Quite a few of my clients purport to being professional Java developers. The problem I have with such a statement is that they always use Tomcat and never know how to set it up. Now, I am not saying that they are not professionals. I am saying that I try and understand the tools with which I make a living and most of the people I have trained are the same way. Anyway, the number one problem I always get asked to fix is log rotation.

Migrate Redmine from MySQL to MariaDB

Submitted by: Slydder

I recently switched from MySQL to MariaDB. As a result my Redmine installation decided to rebel and I, of course, didn’t even notice until a user informed me. The error message that Redmine (ruby actually) threw was not at all cryptic:

“Incorrect MySQL client library version! This gem was compiled for 5.1.63 but the client library is 5.2.13-MariaDB.”
