Speaking of which, is anyone going to implement traceroute
for UNIX which using icmp echo requests, instead of (semi-)random
udp packets, as the ammo? This is one way which I think Microsoft out
did the old UNIX implementations.
They're not semi (or quasi) random udp packets. They're sequential
Secondly, current router vendors' decisions to prioritize ICMP echo
request as dung-level packets means that traceroute's UDP packets
actually get through at times when pings don't.
Third, I'd be happy to implement it... but I'm not sure this would
be a win. I can see the loss (see paragraph 2), but WHAT is the
p.s. The original question was based on Vadim's rhetorical query
as to router vendors. Learn to differentiate between WISHFUL
THINKING and routing reality. When router vendors pledge to
not drop, and properly route lsrr icmp echo request/reply
that code will be online within 24 hours.
