I found an easy way to find out what Novell Netware servers you are connected to and can access. This requires that you have ncpfs installed in Linux and I'm guessing Novell's Netware client for IPX in Windows. If you do, just type:
slist
And you'll see a quick list of all the Novell machines on your network. If you don't have ncpfs, Ubuntu will prompt you to install ncpfs by running:
sudo apt-get install ncpfs
