if this is all the amanda stuff in /etc/xinetd.d, you are missing 2 other
files, or they can all me in one merged file as xinetd doesn't care. I
merged all mine years ago, and it looks like this now:
--------------------------------
# default = off
#
# description: Part of the Amanda server package
# This is the list of daemons & such it needs
service amanda
{
only_from = coyote.coyote.den
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = amanda
group = disk
groups = yes
server = /usr/local/libexec/amandad
server_args = -auth=bsd amdump amindexd amidxtaped
}
service amandaidx
{
disable = no
socket_type = stream
protocol = tcp
wait = no
user = amanda
group = disk
groups = yes
server = /usr/local/libexec/amindexd
}
service amidxtape
{
disable = no
socket_type = stream
protocol = tcp
wait = no
user = amanda
group = disk
groups = yes
server = /usr/local/libexec/amidxtaped
}

You will need that with later versions of amanda, and those arguments it
points at must be correct.

Humm, no comment there. I haven't touched an amanda rpm in years since the
rpm cannot duplicate the required build environment amanda is designed to
use. Currently running the build from this tarball:
amanda-2.5.2-20070606.tar.gz, configured and built by this short script that
has not been edited in about 2 years now:
---------------------------
#!/bin/sh
# since I'm always forgetting to su amanda...
if [ `whoami` != 'amanda' ]; then
echo
echo "!!!!!!!!!!!! Warning !!!!!!!!!!!!"
echo "Amanda needs to be configured and built by the user amanda,"
echo "but must be installed by user root."
echo
exit 1
fi
make clean
rm -f config.status config.cache
./configure --with-user=amanda \
--with-group=disk \
--with-owner=amanda \
--with-gnu-ld \
--prefix=/usr/local \
--with-tapedev="FILE:/amandatapes" \
--with-debugging=/tmp/amanda-dbg/ \
--with-tape-server=coyote.coyote.den \
--with-bsdtcp-security --with-amandahosts \
--with-configdir=/usr/local/etc/amanda \
--with-config=Daily \
--with-gnutar=/bin/tar
make
-----------------------
using virtual tapes, adjust to suit. Run this, then become root to do
the 'make install;ldconfig;su amanda -c "amcheck Daily"'
And it Just Works(TM), snapshot after snapshot as I stay just in reach of the
bleeding edge, so it hopefully works for you.
