Conn test problems

Then I don't see how the FC8 traceroute documentation would be relevant, as
Michael stated that he can do one from the shell but errors out in Hobbit.

Am I missing something here?

Wouldn't the traceroute used by Hobbit be the same command as the shell?

Actually, ICMP echo-request and echo-reply packets are almost certainly
 not an issue here, nor is packet-filtering/firewalling.  In current
implementations, traceroute by default uses UDP packets to abitrary and
 unlikely-to-respond ports, varying the TTL and using the ICMP type 11
(Time Exceeded) from hops along the way to map the routing path.

The manpage in Fedora 8 says "We start our probes with a ttl of one and
 increase by one until we...got to the "host", or hit a max (which
defaults to  30  hops)".

So, the behavior you're seeing is as documented.  If a firewall were an
 issue in sending/receiving the packets used by traceroute, you'd see
the 30-hop behavior whether the host was up or down.

Josh,


Thanks for helping... The source/destination is on a closed network,
sorry...and I don't own the router...


But, I don't understand, how the traceroute works when the host is
up, but when the host is down it times out???


If it works when the host is up, then you would think the ACL on the
router just before the host would allow my ICMP packets through.


What is your thoughts???
