multiple connections from the same host port 80


So I have a server that has the load average at 6-10. top is telling me that httpd mysqld and named are interested in running. netstat is telling me that there are a bunch (but never more then about 20) of the same ip address connected to port 80. Most everyone connected is connected multiple times. If it were an attack I would expect that the connection would be there a lot more then 20 or fewer times per ip. I guess my question is, could this be some kind of attack, or just that there are a lot of mysql calls?

Oh yeah, another cute thing is that the server seems to be connecting to itself a lot.

Thanks for any help,
Michael

Hey Michael,
Can you post a sample of your "suspected hacker activity" out here? As in .. lets see the connections to port 80 here. That way we'll be able to better understand the problem.

The self connections is not a thing to worry I'd say. There are probably daemons running on your server. The application itself is making those internal connections to those daemons.

If are there any outgoing connections from your server lets see them.

Cheers
Arvind
