Here’s a decent post on its installation: http://onlyubuntu.blogspot.com/2007/05/how-to-install-webmin-in-ubuntu.html

Ubuntu is a Debian-based distro, so things worked just fine for Etch.

as an alternative to putting a gui on the server, consider webmin:
http://www.webmin.com/index.html

I installed it on fedora 7 with gnome and kde (but running IceWM)
and then on my Debian Etch server with no gui (and no monitor, keyboard or mouse.)

The resources available without a gui installed on the server are nearly double what’s available on the fedora box (both have only 256 mb ram each) and and you still have a web-based gui, without incurring the overhead of the vnc server and client.

I made my headless server beep when it reaches the login prompt.
Here’s how:

from http://leb.net/blinux/list-archive/blinux-list/2000/msg00628.html

when the logon box comes up I’d like to hear a double beep.

This is not hard either, but a little tricky.
Replace the file /etc/issue with a simple file
that has two control g bells in it.

how to do that I found here
