running openHAB3.2-stable on openHABian 1.7.3 and setting up amanda backup I ran into the following error:

openhabian@openHABUtilities:~ $ sudo su - backup
[14:39:38] backup@openHABUtilities:~$ amcheck openhab-dir
Amanda Tape Server Host Check

Amanda Backup Client Hosts Check

(brought to you by Amanda 3.5.1)

funny thing: the hostname is openHABUtilities:

[14:44:09] backup@openHABUtilities:~$ hostname
openHABUtilities

but even login-screen shows openHABianDevice:

Your hostname is openHAButilities so you need to use that in the disklist file if you want to backup that box/partition.
Or create that hostname for it
Login screen is unrelated. Firemotd (which creates that) is broken.

for everyone else, the disklist file is located here in a openHABian-led installation:

  • /etc/amanda/openhab-dir/disklist

after changing the hostname in that file it now worked.

Is there a reason why the openhabian-config amanda setup uses hostname “openhabian” in disklist even if the real hostname (see command “hostname”) is different?
