Just a wild guess, but a Google search yesterday on "cannot read header: got 0 instead of " lead me to problems with IPv6/IPv4. I recompiled Amanda to use only IPv4 (./configure --without-ipv6) and the problem is gone. To further diagnoze the problem, look at the debug files, you would see that one side of Amanda opened a socket on IPv6: amandad.20080821100912.debug:amandad: time 2.679: stream_server: waiting for connection: ::.51629 while the other side try to connect on IPv4: dumper.20080821100912.debug:dumper: connected to 10.41.170.14.51629 I used information from http://archive.netbsd.se/?ml=pkgsrc-users&a=2008-02&t=6414321 As you don't mention anything about the operating system of the server and the client, I don't know if that helps. I am running FreeBSD 6.3 on both sides. Best regards, Olivier
