For FYI :) I realize that ICMP is not the best way to test and it is not a true indication of slowness or the presence of a problem.
Which begs the same question I've asked in the recent past: then what *is* a good diagnostic tool? If ICMP "is not the best way to test", then what is? What other globally-implemented layer 3 or below protocols do we have available for troubleshooting? Sure, UDP-based traceroute still relies on ICMP TTL exceeded responses to work. I've no idea what TCP traceroute relies on, as I haven't looked at it. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
