Dear my friends...

I use OpenSuSE11.1.

How can I know which TCP port number is being occupied? And how can
I know which service is using a certain port number? All I know only
turn off the firewall and doing "nmap -PN [FQDN-hostname]".

I get this error (in /var/log/mail) as I want to start my postfix:
postfix/master[10597]: fatal: bind 127.0.0.1 port 10025: Address
already in use

Thank you very much in advance.

The command (as root) "lsof -i" shows what you want to know...
