Debian Buster doesn't bring systemd-units for amanda, right?
I applied my own files now.
Edited hosts.allow
amservice succeeds.
amcheck not:

what ...
Does someone use current Debian w/ amanda and bsdtcp?
Hints welcome.
I was able to fix it with some chown/chmod/setuid stuff, setting the
Listener to a specific NIC etc ...
I am surprised that the Debian package doesn't bring working
systemd-units. Do you all use "auth=ssh" ?
IMO that doesn't perform optimal, it seems that it is limited by one CPU
core, right?

I am trying to optimize an installation and pinpoint the bottleneck.
The amanda-server has a 10GB/s NIC, and a 2TB SSD as holdingdisk.
"atop" shows the holdingdisk at ~100% while it only writes with ~100 MB/s.
In local benchmarks I am able to write with more than 220 MB/s.
OK, only one of the amanda client hosts delivers via 10 GB/s NIC as
well, the others are 1 GB/s only.

I defined this in amanda.conf
define interface chelsio {
comment "10G NIC"
use 10 Gbps
}
and use it in all DLEs in the disklist ... because that NIC is running
all the dumps.

I disabled compression for test DLE to focus on network and storage.
A 40 GB DLE gets an
Avg Dump Rate (k/s) 113744
I expect more. Any ideas?
