Subject: RE: !H !H !H!H
On the traceroute command:
!H is returned 3 times if an access list prevents a router from forwarding
the
packet to the HOST. The 'trace' command is used to determine the route
taken
to a remote host. All the hops are shown as the trace probe moves toward
the
destination. Three probes are issued. The response time of each probe will
be displayed if successful.
The trace command returns a N if the network is unreachable.
The P is the response if the protocol is unreachable.
An * is a timeout.
!H is the return for what I said above but it is regarding a traceroute
command,
and not a ping.
