Hi,

I am trying to close all possible ports on my solaris and linux servers.
I am stuck on the following ports on both Solaris 10 (local zone) and Linux (Suse) servers.
Here is nmap output :

PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
1720/tcp open H.323/Q.931
1863/tcp open unknown

PORT STATE SERVICE
22/tcp open ssh
1720/tcp open H.323/Q.931
1863/tcp open unknown
8080/tcp open http-proxy

As you can see in bold on both servers I got 1720/tcp and 1863/tcp ports (telnet as well shows that it is listening).

Do anybody knows what is listening on these ports ?
I try to keep only ssh and web ports.

(I tried lsof/netstat/fuser and stuff but no result with these ports).

Thanks.
