No, but in the tcpdump trace below, I would add "-n 1500 -X" to verify
what exactly is sent.
OK, here we go. It looks like it's sending a request to get the size of
everything in the disklist for that server, which I think is the correct
next step. This one is really big, so I'll just link to it:
http://bway.net/~spork/amanda-tcpdump.txt
You'll note that the "frags" thing is still set, but if you compare what
the server sent to what the client received, it is identical.
I'm totally stumped here. We had another server just start doing the same
thing the other day. They are all on the same subnet/lan/switch, two
don't work, the remaining 10 or so do.
If you're brave, yYou could also try to "strace" planner.
Because planner is a suid-root program, you need to make an "strace"
copy with has also the suid-root bit set. Then add that command in
the amdump shell script around line 100, which then becomes a long line:
/usr/local/bin/strace-suid -o /tmp/planner-strace -s 1500
$libexecdir/planner$SUF "$@" | ...driver...
I'd really like to try and ktrace "amandad" on h13 to see if it sees this
last thing come in or not. Another odd thing I'm noting in the tcpdump is
taht all the other commands that aren't fragmented have a "UDP checksum
OK" message...
Really open to any ideas on this one.
Thanks,
Charles
(and don't forget to remove the strace-suid program afterwards!)
