Re: Fedora 8 ports open

What's opening the ports?

SSH, POP3, RCP, IMAP and something using port 995... you should never
run without a firewall.

To use your "well-known ports" example, port 995 is pop3s (secure
pop3, much preferred from wireless hot-spots).

As root:
lsof -i :22,110,111,143,995
or
netstat -pan | egrep ":22|:110|:111|:143|:995"

Thanks guys. I neglected to mention that I am configuring shorewall. I had
forgotten to add it to the startup scripts. When I start shorewall all is
well.

I think, in general it is not OK to have these ports open after a fresh
standard install. So I guess, you did select something like
mail-server setup -- and than however, it does not make sense to block
them on all interfaces with a firewall.

Beside the fact, that it is rather useful to run a firewall on a box
connected to the net, it may be a good idea to disable the running
services if you don't need them.
