You can now download Novell's client for Linux (still in beta). I haven't tried it myself because it seems closely tied to their distribution (SuSe 9.3 and/or Novell Linux Desktop 9) and I'm, for now, using Xandros. You can read the install instructions and other information here.
But if you are using Linux as your desktop and need access to Netware servers, this is one way of doing it. Whether it is the best way depends on what version(s) of Netware you are trying to connect to and what Linux distribution you use. As, it seems, with many applications in Linux, if you aren't using the exact environment they specify, you probably won't be able to install, configure, or run the application. Thus, my warning that you be using SuSe 9.3 if you are going to try this software.
Aloha!
