My guess is that there is a firewall blocking the ports that AFS uses (udp
7000-7003 or so).  You could try running /usr/arla/bin/rxdebug against
those ports on some interesting hosts (like {anna,lise,houting}.pdc.kth.se)
to see if you get any packets through at all.  Try rxdebug at home or PDC
and compare results.

Not all hosts use all of those ports. 7001 is the default port the client
listens to, to receive notifications about changed files on the
server. That one can be changed on arlad's command line using
'--port=<number>', the others are server ports and don't change.

Ask your sysadmin if they could open up ports 7000-7003 in the firewall.
