Right.
Amanda client services are started by inetd on Debian Buster.
(One could probably write a systemd amanda-client unit quite easily, but so what...)

Yes, some of our Amanda clients are Debian Buster based and they seem to behave fine.

On the backup server ("hegel") we have disklist entries like this (example for client "kant"):

kant.intern.xss.co.at / {
  user-tar
  auth "bsdtcp"
} -1 eth0


As mentioned above on the client ("kant") the amanda services are started via inetd.

So in /etc/inetd.conf we have the line:

amanda stream tcp nowait backup /usr/lib/amanda/amandad amandad -auth=bsdtcp amdump amindexd amidxtaped

(we don't use tcpd)


In /etc/amanda-security.conf we have the following lines uncommented:

runtar:gnutar_path=/usr/bin/tar
tcp_port_range=512,1024
udp_port_range=840,860

Permissions might be important:

root@kant:~# ll /etc/amanda-security.conf
-rw-r--r-- 1 root root 2036 Jan  3  2021 /etc/amanda-security.conf


Then there is /etc/amandahosts:

root@kant:~# ll /etc/amandahosts
-rw------- 1 backup backup 55 Jan  3  2021 /etc/amandahosts

In /etc/amandahosts we have:

localhost backup
hegel.intern.xss.co.at amanda amdump


Finally open up the relevant port on the firewall, if any.


That seems to be all we had to do to get the amanda client
up and running on Debian clients (I hope I didn't forget
something important...)
