going from Xwindows to console

[jekillen <jekillen@prodigy.net>]

Hello;
I've installed Debian 4.1 and would like to know how to
drop out of Xwindows into a console display. It seems
to be different from distro to distro. I tried F1, F2, etc;
command F1, F2, etc;
alt F1, F2, etc
shift F1, F2, etc
control F1, F2, etc.
So what is the magic incantation on Debian?
Xwindows usually runs on tty7or  tty8 as I
recall from Mandrake and Yellow Dog. And
it is accessed via F7 or F8.

Another question, I have installed without
the installation process contacting a mirror site.
The machine is on local net and I have had
another machine function as an http proxy
but disabled the proxy function because someone
discovered I was running a proxy for outbound
net traffic and was using it to bounce request
and tie up my network connection (static ips).
So, now if I want to install software from the
cds, I assume I need a public net connection.
Is that a correct assumption? I can hook it up
to a public ip address directly just for the sake
of software installation, BUT I would rather not.

Does Debian use tcpwrappers?

Thanks in advance;
Jeff K
