Hi Richard,
this depends on the programms you are using.
check the file /etc/services to get a complete list of ports & programms.
The main ports are :
21 FTP
22 SSH
23 Telnet (unsecure - use SSH)
25 STMP (to receive mail)
80 (Apache Webserver)
81 (Control Panel)
110 POP3 - to get Emails
Cheers
Tobi
