Code: [Select]

netstat -a -n will list all currently open ports. If your server application is running the port it uses should be listed here.

And if for some odd reason that doesn't work, you can scan the server either remotely or locally with Nmap.

Are you on Linux or windows? If you let me know I can give you detailed install and run instructions for either OS.
However, if you have already installed Nmap, use this command:

nmap -sS -P0 -O 10.1.1.1


Replace 10.1.1.1 with the server IP. This will give you a list of all the open ports, as well as the Operating System on the Server, and this is the quickest but effective way of doing it. The -P0 is a zero, not the letter 'O', whereas the -O before the 10.1.1.1 is a letter in the alphabet. This command can be run either from the server, or from a remote host.

Ok, you will need to download and install
http://download.insecure.org/nmap/dist/nmap-4.23RC1-setup.exe

Then it should install a shortcut to your desktop. Then it's a matter of double clicking on that shortcut, and either choosing a pre-defined scan, or making your own with the options I previously stated. Any trouble, give me a yell (by the way, nmap is a lot faster on the command line in Linux, but this still works). This nmap install file will also install Winpcap, which is needed for this and packet sniffing.
