what is using port 988?

kghoshal · 08-01-2003, 04:03 AM

I've run nmap against a Red Hat Linux 8.0 box to find the open TCP ports.
It found 21, 23, 111, 139, 513 and 988.

I enable ftp (21), telnet (23), nfs (111 ?), samba (139 ?) and rlogin(513), but I am at a loss to account for port 988. Any suggestions?

you can also try the following:

Code:

lsof -i TCP:988

here's an example from my linux box at home:

Code:

turnip:~# lsof -i TCP:80 
COMMAND   PID USER   FD   TYPE DEVICE SIZE NODE NAME
apache    389 root   16u  IPv4   2986       TCP *:www (LISTEN)
apache  11785 root   16u  IPv4   2986       TCP *:www (LISTEN)
apache  11786 root   16u  IPv4   2986       TCP *:www (LISTEN)
apache  11787 root   16u  IPv4   2986       TCP *:www (LISTEN)
