healthy installation on os x does not connect at some locations

At PDC rxdebug is in /usr/openafs/sbin/rxdebug

The following commands should give output
from your MAC:

  Against one of the AFS DB servers:

  rxdebug anna.pdc.kth.se 7007 -version
  rxdebug anna.pdc.kth.se 7003 -version

  Against the fileserver your $HOME is on:

  rxdebug sculpin.pdc.kth.se 7000 -version
  rxdebug sculpin.pdc.kth.se 7005 -version

The following command should give output
when executed on PDC:

  /usr/openafs/sbin/rxdebug angr.Fysik.UU.SE 7001 -version

The ports are as follows (all UDP):

7007: AFS Volume location database
7003: AFS Users and groups database
7000: File server (files)
7005: File server (volumes)
7001: Client

So for this to work, the firewall has to be opened for these ports.

If your sysadmin has any questions about AFS or firewalls etc, point
him to the PDC support.
