would you run this little script, please
if you have a bsd, linux , or probably cygwin machine, would you please run the attached script once as a favor to a research project? it simply does a traceroute to a eight targets in four locations around the net to see if they are reachable from your site, and, if not, where the route dies. this is a small part of a larger experiment, so try not to jump to too many conclusions :). if things are as we suspect, we'll try to present the analysis in toronto. thank you! randy

I did run it from several place around the world. Please note that the syntax is not working with the NANOG version of traceroute. One should use traceroute.lbl instead. Also, because it's often easier to wget a file than having it in your mailbox, I put one version online, ask me to remove it if you're against this. http://opa.loque.org/~vt/in_probe-v1.4.sh http://opa.ipv6.loque.org/~vt/in_probe-v1.4.sh -- Vassili Tchersky Réseau Koumbit Network VTC1-ARIN

I am on a NetBSD machine. What did you want from ifconfig? I am guessing "ifconfig -a". -- D'Arcy J.M. Cain <darcy@druid.net> | Democracy is three wolves http://www.druid.net/darcy/ | and a sheep voting on +1 416 425 1212 (DoD#0082) (eNTP) | what's for dinner.

yep. just trying to learn whence the trace originated. this was supposed to be fixed. apologies. also the ! in the mail test is reversed. also was supposed to have been fixed. and heas had a good sendmail direct hack that got missed from the review set. <sigh> and yes, there are problems on old bsds, some fedoras, ... with the -I on the traceroute. but, in tests, udp traceroute gave much worse results despite icmp trace theoretically not working as vern points out that rfc 792 (4th paragraph of intro) says The ICMP messages typically report errors in the processing of datagrams. To avoid the infinite regress of messages about messages etc., no ICMP messages are sent about ICMP messages. but, my deep apologies for not personally testing that the test folk's corrections were made before sending. grrrr randy
