[comp.dcom.lans] NCSA packet ver does RARP?

dixon@gumby.paradyne.com (Tom Dixon) (06/14/89)

I am running NCSA Telnet ver2.2d, the one that comes from clarkson.edu
and communicates with a packet driver for a WD8003e.  Everything works
fine except RARP.  I have determined that my RARP server is returning
good packets but the Telnet quits trying and complains about no response.
If I specify the IP number in the config file, it works and I can connect
to any machine just fine. (So ARP works, just not RARP).

I have no Bootp server so thats out (if you have info on bootp, I'll read
it....).

Anyone see anything like this with this software/hardware before care to
offer suggestions as to possible problems to check  for and possible
fixes?

Well, I made a mistake.  The packet driver has to explicitly
request each ethernet type field that is to be used by the client.
NCSA always requests IP, and ARP. But RARP slipped my mind.

You can get a bootp server from lancaster.andrew.cmu.edu
or write to ww0n+@andrew.cmu.edu

"Its fixed in the next release"

Of course, the built in WD8003 driver correctly handles rarp, but
then you can't use it w/ Novell etc.
