A while back I asked this group about third-party traceroute and got very
positive results; we now have it running here and it has proven extremely
useful for debugging network routing problems. The problem now is that
it does not seem to work on SunOS 4.1.1 (we have it working on 4.0.3
and 4.1 systems). Other things using the NIT driver work fine under 4.1.1, 
such as "tcpdump". The message I get is:

traceroute: nit output socket: Protocol not supported

Did I leave out a needed kernel option that would explain "etherfind" and
"tcpdump" working but not "traceroute"? (It doesn't work with the GENERIC
kernel either). Did Sun break the NIT driver in 4.1.1? Does anyone have 
traceroute running on SunOS 4.1.1? We get the same message on both Sun-3 
and Sun-4 architectures under 4.1.1.

AdvTHANKSance,
