[AC-Admins] Routes

[Pippin Bear]

Hmm, may as well copy this to everyone else too, in case it's useful.
(I don't think traceroutes are particularly sensitive w.r.t. public
archiving.)

(Wheee, just done some actual C hacking for the first time in
dunnohowlong, to adjust the field width of "mtr --report" so that the
hostnames aren't truncated into uselessness.  Icky code full of magic
numbers and junk.)

(Also, of course, these only record a 10-second snapshot each of the
route between servers.  Routes change.)

(Yes, the name after "HOST:" doesn't match either the source or
dest host you would expect.  It's the actual hostname of the source
machine.  squirrel.anthrochat.net actually runs on husky.floof.org,
husky.anthrochat.net actually runs on beckton.servology.co.uk, but it
says "morden" because I ran the "from husky" traces from a different
machine in the same rack and with the same first-hop router as husky
for reasons which will probably not become clear to you.)
