Title: Ports
Post by: Nate on July 16, 2001, 08:50:45 PM

Can anyone give me a list of ports that must be open on the server for incoming connections.  I have a cisco 678 and I have to specify every port that must forward to the server.  What I would like is a list of ports that must be open for things such as webmail over ssh or the account password changer.

Standard ports for the respective services, i.e., 21 for ftp, 22 for ssh, 23 for telnet, 25 for smtp, 110 for POP, 143 for IMAP, 80 for http, 443 for https--you get the idea.

That helps -- I have already put in most of the common ports -- do you happen to have a list of all tcp ports or know where I can find a good list.

Take a look at /etc/services.
