Failover and loadbalancer using keepalived (LVS) on two machines

Failover and loadbalancer using keepalived (LVS) on two machines
January 26th, 2009

In this scenario, we have two machines and try to make the most of available resources. Each of the node will play the role of realserver, it will provide a service such as a web or a mail server. At the same time, one of the machines will loadbalance the requests to itself and to its neighbor. The node that is responsible of the loadbalancing owns the VIP. Every client connects to it transparently thanks to the VIP. The other node is also able to take over the VIP if it detects that current master failed but in nominal case only process requests forwarded by the loadbalancer.

Crucial Concepts Behind Advanced Regular Expressions | How-To | Smashing Magazine

Regular expressions (or regex) are a powerful way to traverse large strings in order to find information. They rely on underlying patterns in a string’s structure to work their magic.

How To Automatically Scan Uploaded Files For Viruses With php-clamavlib | HowtoForge – Linux Howtos and Tutorials

This guide describes how you can automatically scan files uploaded by users through a web form on your server using PHP and ClamAV.

To glue PHP and ClamAV, we install the package php5-clamavlib/php4-clamavlib which is rather undocumented at this time. That package is available for Debian Etch and Sid and also for Ubuntu Dapper Drake and Edgy Eft, so make sure you use one of these platforms.
