When I first installed linux. I named it penlux. So when I boot i get
a prompt such as this " pentlux login: " How do I change the "pentlux"
(what is the linux label for this?) part? Also when sending e-mail
using the commandline "mail" utility, how do I specify to "mail", a
specific return email address to use? Right now it is using a default


change "pentlux" to my pop server domain!!!!?)

thanks

This is called the hostname (not so much a Linux term as a
networking/Internet term).

It would have helped if you'd told us which distribution you're using.
In Debian it's in /etc/hostname; in Red Hat I seem to remember it's in
/etc/sysconfig/network, though it may have to be set somewhere else as
well. It'll be in /etc somewhere, though. :)

This is a bit of a complex subject. mail originated at a time where
you could expect any Unix system to also be a mail server visible from
the outside world (simplifying, but you get the general idea). You
might want to set up a mail server like exim which can rewrite

Alternatively, you could use a more sensible mailer than mail! pine,
elm, mutt, and others are popular. I agree it's useful to have
something like mail which can cope with having messages piped into it,
though.
