You will probably need to upgrade to Netware 5 and then download the Console One client for Linux.

You could try downloading it and pointing it at your 4.11 boxes. I seem to remember that Console One worked against our 4.11 boxes (albeit I was running on NT) but couldn't get jconsole (rconsole equivalent) to work but that was probably server related setup (I don't support our Netware servers)
All in all, unless you can get the Netware upgraded to 5 then the answer is probably not, when you move to 5 you can use Console One, JConsole, and the web interface to do everything.
