Because SAP implies temporary bindery objects in previous implementations
for routing to operate.

If you are talking about serving NetWare clients, then you are talking
about responding to GetNearestServer() calls from the clients, at the
very least to proxy them, since only a server on the same segment can
respond directly.

That's why Novell coined the term "brouter" implying a combination
bridge/router being necessary -- no flat bridging allowed, unless
you don't expect the hop count to be maintained correctly.


This whole thing started on someone offering to port the recently
released IPX (presumably 3.x or before, without RSA and packet
signatures) server code for Linux.

I don't expect the code to fully support most clients, in fact, because
the number of NCP's you have to support to be a real server is in fact
astronomical.

It might be enough to allow some clients using restricted NCP sets to
operate, in the same way that the MS NT NCP server allows NT and WFWG
and Win95 MS supplie Novell clients to operate (though they offer logins
at the 4.0 level, having hired mathematicians to reverse engineer the
login valid RSA-derived token generation sequence).

If someone is willing to do the port, don't look a gift horse in the
mouth.  8-).
