Ship Apache HTTPd Logs to Graylog2 Via Rsyslog

Loch_à_plateau

This is a quick recipe and a list of resources on how to ship apache logs to a graylog2 server using rsyslog which is the default system logger on CentOS 6. Tested on CentOS 6.4, Graylog2  0.9.6, Apache HTTPd 2.2.15.

Network Bandwidth Testing At The Command Line

Whether when I’ve been designing networks for schools or BYOC parties , I’ve played with ethernet cables long Bangkok_traffic_by_g-hatenough to allow some custom tricks when it comes to bandwidth. The point of this post is *testing* not troubleshooting laaaaaaaaaag nor monitoring.

Nothing can truly emulate a bunch of hardcore gamers, leechers, hackers pushing your network to its limits but prior to opening your RJ45 gates you can certainly do some testing with the help of some command line tools and some basic scripting.
