Hi,
an internal server is running amanda to back up several external servers
on it's DAT drive. between the amanda servers and the external servers is
a firewall running linux ipfwadm w/ masquerading.
since a reboot of the firewall, amanda reports "selfcheck request timed
out." for some (up to four) servers. some servers are never reported (they
seem to repsond to the selfcheck request), the other servers change (i.e.,
servers a,b,c,d are reported to time out, 1 hour later servers c,d,e,f are
reported to time out).
on the "timed out servers", /tmp/amandad.debug looks like this:

amcheck needs approx. 1 minute to report these timeouts.
any ideas what might be wrong ? I don't understand why the firewall
settings which haven't change for some months suddenly don't seem to work
any longer.
tnx in advance.
