The best way would be to ask the admin. Since they are outbound ports and you will be coming inbound, it's hard to find the holes going out. > The friend is NOT a computer person and has NOT much knowledge of TCP/IP > etc so I can't get him to talk to the IT guy easily about those things. Have your friend explain your situation and have the admin write down the available ports. IMHO, The admin really should be running a SOCKS server to allow outbound access. > I know port 80 is permitted but I don't really want to run > a telnetd at that port. That would be bad.
