RHEL for FREE?

So, as mant of you know, RedHat has efectively killed CentOS as a free alternative to running RHEL at home. Because of the blowback from that announcement (I’m sure) then have changed their license for developer use to allow up to 16 servers. This developer license is free and you are free to use those […]

Rsync bug

Bitten by the rsync bug? I was. Apparently in the new RHEL 5.7, and I am sure the RH clones like CentOS, Scientific Linux and ClearOS(?) as well, there is a bug in rsync when you use it with ssh transport like so: rsync -avz -e ssh remotehost:/data /data The fix is to make sure […]

RHEL 5 quick and dirty samba primer

PHP 5.3.X on RHEL 5 / CentOS 5
