[mod.protocols.appletalk] cap problem - finding ddp networks

cck%cucca@COLUMBIA.EDU.UUCP (07/11/86)

It hit me tonight that there's problems in the way the abnet code
picks up the ddp networks.  Problems at mit proved it too.  The
problem lies in the fact that the code really makes three major
assumptions.  First, that you're on a class b network.  Second, that
you don't have anything defined for the KFPS Ipmap table.  Third, that
you are running the KFPS with subnet shift of 8 and a subnet mask of
0xFF.

I don't have a general patch at this point.  (Basically, just too
tired to think about it and don't feel like hacking out the code).  I
will note that the code that causes this problem is fairly localized -
if you look at abInit and see the way it picks out abnet and
absrcaddr.net, then you should be able to patch it quickly for some
particular arrangement by setting the abnet address to the same thing
the KFPS software would.

To let you know what else has been happening, I've found a whole bunch
of small bugs which don't really affect things too much (for the
applications sent out).  In addition, been working on the KFPS gateway
code to send NBP LkUp's to both networks when it gets a BrRq.  This
seems to work okay.  Stubs for RTMP handling are in - but no real
code.  Since NBP LkUp's are going to the ethernet, can watch and
respond - this is step 1 in having a unix server (you can by-pass,
but....) - many many problems with new code right now though, won't be
ready for a while.

Still no documenation.
