We're not using IPX, but...

Just about anything that you'd carry on UDP or TCP can be carried on 
IDX/SPX. Here are the IPX/SPX entries from /etc/services on a UnixWare box 
(an older one; I'm not installing the IPX stack on the new versions of UW). 
Although many of these services are applicable to Unix or UnixWare only, 
some of them probably also apply to NetWare; and as Novell works to unite 
their UnixWare and NetWare products, more and more of these will appear at 
NetWare sites. (Yes, these services are actually used and not just in the file 
for fun; things like X Windows over SPX are used to support the UnixWare 
"Remote Applications" icons). I love the comment field of the "shell" service 
entry...
