Stan's not alone on this one. I have two OpenBSD 4.5 machines also on Sun SPARC hardware. I had this same trouble a couple months ago with 2.6.1, but didn't have time to look deeper. After seeing this discussion, I built amanda-2.6.2alpha-20090812 (can't get 0820 to compile). I'm getting exactly the same errors. I tried dump with and without compression.

My Amanda server is on Solaris 10, and I have a mix of Solaris, Linux, and OpenBSD systems. Except for the above-mentioned build, everything is at 2.6.1p1. There are no firewalls on the Amanda server or the OpenBSD clients.

I know "me too" responses aren't usually helpful, but maybe this will rule out the firewall question, at least.

Fair enough, but I think we can rule that out in this case. First, I
control the 2 computersin question. The Master backus up 55 machines a day
taht consist of a diverse nix of OS'es, and Amanda versions. It's a Linux
machine, and I am not running a firwall on it. The client is an OpenBSD
machine. I use these for my firewalls, so I am familiar with configuring
firewalls on them, Doing so requires (as a minimum) running pf. I am not
running pf on the test machine at all.

I am not certain whether the sendbackup executable, or amandad opens the
port on the client side. My guess is that it is not suceding in doing this.
Thus when the Master tries to connect to it, there is no port for it to
connect to.
