  There was a workgroup client for DOS that used TCP/IP.  I can't vouch
for it's working, but try

  I, also, supported Netware 2 and 3.  I avoided 4 due to NDS and the
availability of Samba.  It was a big deal when the Internet was gaining
momentum.  At first, we had multiple protocols and multi-protocol
routers.  My memory is vague but I'm pretty sure Netware 3 could run
NetBIOS on a TCP/IP stack.

  So, are you looking to move your existing Netware 3 server into a
virtual environment?  Or, are you looking to replace an existing Netware
3 server with a CentOS equivalent?

  I would suggest setting up a CentOS server with Samba and convert the
DOS network stack, if you can.  Samba appears to be much more
supportable, currently.  Take a look at the FreeDOS project, too, as an
example of getting DOS to work in a more recent environment.  The
biggest concern (after getting the clients to talk to Samba) is that
there have been a few choices made in Samba with respect to file
sharing/locking mechanisms.  With old software, you may have to look at
those settings.

  If you attempt to virtualize Netware, you may run into issues, though
it'd be an interesting exercise.  I don't know if a Linux hypervisor
will handle IPX packets without IPX support installed.  You might need
to check for an ipx kernel module.  Also, my version of Virtual Machine
Manager running on CentOS 5 with Xen doesn't give me any sort of Netware
OS option when creating a new virtual machine, so you'll probably have
to play with settings.  I google'd netware virtual machine and saw a few
links to virtualizing Netware 3 under VMWare which might give you some

  Either way, do it in a separate test environment to work out any
issues prior to production deployment.

  If I hadn't been strongly encouraged (successfully) to de-clutter my
software repository, I'd pull out my old Netware 3.12 disks and try
installing on a virtual machine.
