[comp.protocols.tcp-ip] Ping with Record Route Option

wbc@cabot.dartmouth.edu (09/07/89)

I recently requested information on tracing the route that
packets take,  and got some very helpful information, especially
about traceroute.  Someone also mentioned ping, with the record
route option, but didn't have source available.  Does someone
know where I can get this kind of ping, or should I hack one up
myself?

I added record route to "ping" a few months ago at Rutgers, with some more
hackery by Ron Natalie to make for a cisco-style mode.  When both are used you
can throw a bijizillion ICMP Echo packets real quickly at a host and see what
routes, and how many of each, the packets are taking.  I can mail you all the
applicable stuff if you'd like.  I'd also include some kernel mods to make
4.3BSD systems do the right thing with ICMP Echo packets w/options.
