I can't remember really, but I do think I did.
I think I even tried some RPM's made for Redhat 4 but as always I got some dependency errors and I do think I tried to compile one version that I found... somewhere
I know CentOS 4.5(or Redhat 4[u5]) is old as the 'big bang' but if I just could find a ulogd that worked for a newer version, I'd use that one.
Right now I got one machine up and running v4.5 and I don't have any other empty PC doing nothing, so I really don't wanna mess this one up if there ain't no ulogd for CentOS 5 or later.
btw, I use CentOS just 'cos it's a 'Enterprise' version and is supposed to be more stable as a server than to use Fedora, even though I never had any problems using Fedora as my server.
