unknown port 746
 

I ran nmap on my box today and found that port 746 is open. This port wasn't open before. I can't find out what program is using this port to shut it down either. When I netstat -tulap I get...
tcp 0 0 *:746 *:* LISTEN root 1386 -
tcp 0 0 *:ssh *:* LISTEN root 1398 -

I tried using iptables to block it, but it opens another port. Any ideas what this might be and how I can shut it down if I don't need it running? All nmap tells me is...

746/tcp open unknown

Try netstat -nap
It lists the programs that have a port open.

Also try looking up the process id (PID) that is listed:
tcp 0 0 *:746 *:* LISTEN root 1386

Use cat /proc/1386/cmdline

try to use this command :-

fuser -v 746/tcp

or

netstat -tlnp

Hope this helps. cheers!
