I've encountered a very annoying problem with telnetd/route/godknowswhatelse
when I telnet into my machine directly from a Mac using NCSA Telnet.  Telnet
from a unix machine works fine -- i.e. if I telnet to a unix machine from my
mac and then telnet from the unix account to my machine -- but if I telnet 
directly to my machine with NCSA Telnet, routing seems to go haywire.  This 
happens after any amount of time -- from a few minutes after starting the
session to an hour or so.  I monitored routing information, and the following
ensued:

# route monitor

angler is the mac in question, isb-ags is the router for my netbsd machine 
(and also the mac).  Here is the routing table for the netbsd system:
# netstat -r
Routing tables

Internet:

I'm using Arne's 1.1_ALPHA kernel:
# uname -a
NetBSD maxine.cc.vt.edu 1.1_ALPHA NetBSD 1.1_ALPHA (GENRIC) #6: Fri Nov 17 11:09:45 MET 1995     arnej@storm:/home/stormd/arnej/cr/usr/src/sys/arch/pmax/compile/GENRIC pmax

I was having the same sort of problems with the generic kernel on Jonathan
Stone's miniroot.  Has anyone else encountered this, or have an idea as to
what's happening here?  
Thanks
