Hi, all.  Just recently, I added an Ubuntu Linux box to my series of Debian
servers.  All the stock Debian servers had backed up fine.  However, my
Ubuntu box fails miserably.  Going through the client's debug log, the thing
that really stands out is this:

amandad: time 0.000: sending ack:
----
Amanda 2.4 ACK HANDLE 001-B8CA0608 SEQ 1137474902
----
amandad: time 0.000: dgram_send_addr: sendto(0.0.0.0.858) failed: Invalid
argument


A "strace" run on the client's amandad shows the following interesting
snippet:

sendto(0, "Amanda 2.4 REP HANDLE 001-F0B70608 SEQ 1137547581\nERROR [addr
0.0.0.0: hostname lookup failed]\n", 95, 0, {sa_family=AF_INET6,
sin6_port=htons(847), inet_pton(AF_INET6, "::58d0:f6bf:c927:f6b7",
&sin6_addr), sin6_flowinfo=0, sin6_scope_id=134513844}, 16) = -1 EINVAL
(Invalid argument)


It looks to me like the client -- which *is* IPv6 enabled, but has no IPv6
interfaces -- is thinking IPv6-ish thoughts.  Some Googling showed a thread
on this back in '03, and implied that a patch had been merged.  Since I'm
running 2.4.5, I would have thought that would be yesterday's news.

Any ideas on what to do?

Thanks!
