Grex Info Item 167: Hop? question
Entered by patrick on Tue Jul 12 14:52:53 UTC 1994:

Does any one have any info on ?hop? or something like that?
It goes out and pings and lists all the spots it hits along the way.
My apologies for my UNIX ignorance.

The program you're looking for is "traceroute".  It's installed here on
Grex in /usr/local/etc, but for some reason is permitted such that only
staff can use it.

I believe steve explained this a while ago - traceroute is a very
link-intensive program, and if everyone used it, our link's
peformance would be sloooooooooooooooooooooow.

That's interesting.  As far as I know, traceroute isn't any more
bandwidth-intensive than "ping" is.

I don't know why it's permitted the way it is either, but I do know
while it doesn't exercise the system all that much, it *does* do a
number on the name server, which isn't as stable as it should be in the
first place.
