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
