Similarly, I haven't use squid for many years and likewise dansguardian. Apache/PHP/MySQL are all starting to show their age on CentOS-4.x but thankfully, there is CentOS Plus repository for updated php & mysql but if I were thinking in terms of updates that I didn't have to bother with for a few years, I would certainly go all the way to CentOS 5 You might find some useful information here... http://centos.org/search.php?query=upgradeany&andor=AND&action=results&submit=Search Craig
