Great, thank you, Marko. I had read the thread, but first it didn't make sense
to me. From Stephanes last reply I found that this is all I need:
user@host:~$ host guest1 10.0.3.1
Using domain server:
Name: 10.0.3.1
Address: 10.0.3.1#53
Aliases:
guest0 has address 10.0.3.123
I have one more question (not urgent, but making this work would be
nice-to-have):
Connecting using the hostname fails:
>user@host:~$ ssh ubuntu@guest1
>ssh: Could not resolve hostname guest1: Name or service not known
Can you suggest what needs to be configured to make this work?
Thank you
Alan
