The trouble is, the TTL drops one by each hop. Something interesting
that people running PM's and USR Total Controls should know:
Watching tcpdump of ping's bouncing around in a livingston only
network shows that the PM only lets one ping bounce around
and it then dies after bouncing 255 times.
The Total Control bounces around forever (the packet never dies)
off of the Livingston router, eventually saturating the ethernet if
you get too many of them doing this. This does not happen if you
are pointing the TC at a Proteon Router. We have not tested
pointing it at a Cisco.
Some weird interaction is what is causing this. USR is *very*
aware of the bug (and is probably quite sick of me). I'm trying
to reach Livingston to figure out why ICMP packets are seemingly
processed in order whereas the TC throws out as many as it can
juggle at one time.
