This thread needs to be moved to the development area.

For whatever reason your computer thinks its primary name is worker01.
I can get the same thing (also a 20.04 computer) if I login using an alias computer name:


doug@DOUG-64:~/config/etc/bind$ ssh doug@test04

doug@test04's password:
Welcome to Ubuntu Focal Fossa (development branch) (GNU/Linux 5.4.0-18-generic x86_64)

Now, here is an excerpt from my related DNS stuff:


doug@DOUG-64:~/config/etc/bind$ cat db.smythies.com

Hi
what Ubuntu command have you used to change to doug@test04's password: ???

Cheers

CheersI didn't use any command. My point was that sometimes computers can have multiple network names that end up at the same place. However, they typically only have one reverse lookup answer. So in my example, I logged into 192.168.111.112 via one of many possible names, but the computer itself, thinks its name is "s15".
