Transferring Conserver Logs to Elasticsearch

If your organization manages Linux, AIX, HP-UX or Solaris servers
in-house, chances are your system administrators at least
occasionally need low-level access to those devices. Typically,
administrators use some kind of serial console—for example, traditional

(IPMI). more>>

I recently was talking to someone over IRC who was helping me with a PHP
app that was giving me trouble. The extremely helpful individual asked
me to let him know the value of a certain field in a record on my MySQL
server. I embarrassingly admitted that I’d have to install something

Vagrant Simplified

I admit it, some tools confuse me. I know they must be amazing, because

High-Availability Storage with HA-LVM

In recent years, there has been a trend in which data centers have been

DNSMasq, the Pint-Sized Super Dæmon!

I’ve always been a fan of putting aftermarket firmware on consumer-grade
routers. Whether it’s DD-WRT, Tomato, OpenWRT or whatever your favorite
flavor of “better than stock” firmware might be, it just makes economic
sense. Unfortunately, my routing needs have surpassed my trusty Linksys
router. more>>
