Yes Jon, we even opened up the firewall and still have the problem.

Furthermore, there is progress:

I have created a similar config, and tried to backup only a small 
portion of the host. It worked. Now, I have started a full dump of the
whole host in the same config and so far, it works. Why ? I don't know
! Before trying this, I rebooted the amanda tape server, but I don't
think that's what fixed the problem.

Also, the new config is using ufsdump instead of tar for the / file
system of the host. I'll switch to tar later and try to reproduce the
problem. Problem started occuring on this host when I switched the /
file system from ufsdump to tar, then issued an amadmin force for the
/ filesystem. Next run, it hung and refused to work ever since...

Could it be the etimeout ? I really dont think so, according to the
logs, the estimated takes  a lot less time than 600 seconds !

I'll keep you informed 

Thanks
