I just recently got a firewall configured and am trying to learn what the info it provides really means. The last day or two I've gotten a series of hits id'd in the log as sub7 on port 1234. This mornings series were reported as from host bama-live.webnet.advance.net. Is this a common thing? Does it mean that a server at that location is infected with the trojan sub7? How to interpret this info? I've searched the internet, got some info about what sub7 is and does. But how would you know if you were infected/invaded by the thing?

As long as your box isn't listening for connections on port 1234 (or any out of the oridinary ports), it's more likely that the remote host was just checking to see if your box was running sub7 and the firewall caught the probe.

Show me an example of the firewall log and I'll translate it for you.

1234 207.155.252.9 subseven Jan 30 10:48:29
1234 207.155.252.9 subseven Jan 30 10:48:31
1234 207.155.252.9 subseven Jan 30 10:48:33

This is a sample from the hit list. I don't know if that's what you meant. The firewall is Firestarter.

Your firewall log doesn't seem to give much info.
but kill-hup's correct looks like a subseven scan.

These sub7 scans and another set that are id'd as trin00 come from the server for a set of forums that I visit. Would they be scanning these ports for some good reason, or does this indicate someone using their servers for malicious purposes? Oh yes, another set of hits from the same server is on the nfs port. All are suspect, eh?
