Hi all,

I ran "rkhunter" immediately after the "chkrootkit" run finished, and
it reported no problems. How do I determine if this is a false alarm
or a real problem? If this is a real problem, what should I do about
it? Also, as I'm neither a security expert nor a sysadmin, what is
port 3133 used for?
thanks,
Bill.
I realized a lot later that I also should have mentioned that the
"chkrootkit" run was shortly after doing "yum update", "prelink -a", and
rebooting. I don't know if that's significant.

??? I looked at that long sh script. It didn't help. I don't see how
knowing that chkrootkit uses "netstat" to check a port tells me whether
or not I have a real problem. I don't understand what it means that a
port is infected. I am a home user stuck doing his own sysadmin and
security with no training or experience in these things.
Do I have a security problem? If yes, how do I fix it?

Thank-you.
thanks,
Bill.
