Does it work as root? Is pbs_iff setuid root?
Can you run pbs_iff in test mode? It should go something like this:
$ pbs_iff -t warp31.physik.tu-chemnitz.de 15001
$ echo $?

That's good. MOM<->Server connections don't require a AuthenticateUser
req first, so we know the problem isn't very deep.

Can the server get proper DNS forward and reverse resolution of
If the pbs_iff stuff above is all true, does acl_host_enable=F allow the
client to connect?
