Does anyone have ``traceroute" running on a Sun-4 running SunOS4.0? I can't seem to get it to work even after having made the necessary kernel mods. Aloha, Torben

I would like to have diffs to the >sources and not binaries!! I have all of the patches necessary to the Sun kernel to fix the NIT bug. So do a lot of other people I think. How about bugging Sun to put them on UUNET along with the other patches there? If you're looking to get something like ``statspy" running, I have the patches for that to make it work on a Sun-4. But maybe Bob Braden and Annette DeSchon have an ``official" version by now that'll work across both architectures. Aloha, Torben

I got a number of requests from other people who wanted to know if I found a solution to a problem I thought I had with getting ``traceroute" to work on a Sun-4 earlier. Well, the reason was simple. I generated objects for the kernel mods required and then I generated a ``new" kernel using the old objects. Sad. And pretty dumb :-( So the problem is solved. Mea culpa. Torben

I am looking for a utility which can tell me what route packets have taken between two endpoints, showing switching to alternate routes etc. Is traceroute the right thing? What exactly is traceroute doing? Where can I get it from and how? thank you armin Armin R. Schweizer, CIBA-GEIGY AG, R1045.P.06, WRZ 4002 Basel / Switzerland phone: -41-61-697'79'46

Armin: The record route option is the only way of finding out the exact path that a packet from point A to point B. The ICMP packet with the recorded routes may or may not get back to you. If you're having problems getting to point B from point A, you can use trace- route to help identify where your problem might be occurring. Traceroute uses an undefined UDP port and the time to live (TTL) header option. In its default mode of operation, it transmits its first packet to the destination with a TTL of one. It will normally transmit two more packets with the same TTL after an internal timer expires or after a time exceeded packet is received before incrementing the TTL value. For each TTL value it displays the responding host name and the round trip time for each of the packets transmitted. Traceroute continues incrementing the TTL until the default maximum of 30 is reached or until a port unreachable response is received. At best, you can infer that this is the path your packets were taking to point B; however, you may find a different path being reported should you re-initiate traceroute. Merton

Traceroute can also use source-routed packets, so that one can attempt to examine the path that packets are taking on their way back to you. However, some systems don't report all the interfaces, etc. Like the nss, that apparently only decrements ttl once, even though it goes through lots of interfaces. Record-route does appear to capture most of the interface addresses. However, record-route is limited to 9 addresses! A source-route, record route ping would be a nice thing to try. Anyone got one?

Can someone tell me where I can get a copy of traceroute for Ultrix 4.0? =========================================================== Jim Lennie jlennie@vm.uoguelph.ca Communications Services 519-824-4120 Ext 2588 University of Guelph Guelph, Ontario ===========================================================
