Me neither... Is there any way to increase the verbosity of amandad?
inetd config is good (it's a client, so it's only got the single line
for amandad), nothing in the system logs, all of the stuff in the
libexec directory appears to have correct perms (the proper things are
setuid to my amanda user)...
No, but in the tcpdump trace below, I would add "-n 1500 -X" to verify
what exactly is sent.
The devel2 (server) view:

I'm not a tcpdump guru, it is suspect that the "client" sends something
flagged as "frag", while the server does not see the "frag" flag.
Could be tcpdump implementation difference on the two machines too.
The server side logs some info in the amdump file, when it receives
the packets. Alas only after decoding them. If the server
didn't see them, it won't log anything. Have a careful look anyway
in the amdump file around that time (the dumpfile contains milestones
in seconds from start of file, so that you can locate the lines around
which the packets were received.
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...
(and don't forget to remove the strace-suid program afterwards!)
