Yes, on marvin (192.168.42.103)

I don't know how. I have not much clue about nameservers...

You are right: 192.168.42.103 is "eddie.galaxy.home". Eddie is the
computer, on which i do the "telnet marvin 25". Do you have a hint how
to stop eddie doing that lookup ? (There is no bind running on eddie...)

/etc/hosts on eddie and marvin contains the line:
192.168.42.99 marvin.galaxy.home marvin

No, I have four computers which rely on their /etc/hosts.

I dont have any idea what you mean ;) Sorry, never had time to learn
more about bind...

Well, I first had to learn a lot about bind - it's not fair to let you
do all the work... Do you have any hints, what I could read ?
Perhaps, you have another hint to help me, now that you have new infos ?
Thank you very much for your help !
