permissions of /dev/ait2 are group readable, maybe you need
to add "groups = yes" in xinetd.conf to enable the additional groups
that user amanda is in.

Any other suggestions other than migrating the firewall to iptable which

do not remember anymore, but maybe there is a possibility
to not do NAT for a certain portrange/host ?
I re compiled amanda client as below:
./configure --with-user=amanda --with-group=disk
--with-configdir=/etc/amanda --with-udpportrange=1001, 1009
--with-tcpportrange=11000, 11300

amrecover to work, you need to open up:
backup server: 10082(udp), 10083(udp), a small range of tcp ports for
data transfer e.g. 11000:11030 (recompile amanda with
--with-tcpportrange=11000,11030)
I believe 10082 and 10083 are tcp, not udp.

didn't try that yet, curious for result however...)
Or: put that path in a file local on the workstation-millerlu
(and avoid having a space in the path of that file :-) ), and
set
exclude list "/path/to/file/containing/excludepatterns"

ngdisk will fill a tape, insert a tape,
and during the next run, Amanda will autoflush the collected images,
together with the backup of that night to tape.

ust a little around the limit. Heavy load on the amanda
server makes it flip over, and when you do in the morning again, it is
the only backup, so it is much faster.
Certainly take a look on the /tmp/amanda/*.debug files too.

be put on tape again on the next tape. It would be better if
Amanda put the larger dumps not at the end of the tape, if possible.
Just add the amanda.conf parameter "taperalgo largestfit" to
the setup. For a complete explanation, also read:
