Subject: UML console access
Date: Fri, 14 Feb 2003 15:09:43 -0500
From: David Coulson <david@...>
I've now sucessfully implimented console access to UMLs. This can be
used to recover the system if you mess up networking.
Before being able to access a console, you first need to enable your UML
to listen on a specific terminal, either a tty or a serial port. To do
this, you would use a line similar to this in your /etc/inittab
S0:2345:respawn:/sbin/getty 38400 tts/0
This will setup a getty listening on tts0, which is the 'first' serial
port on the system. You can access this by shelling to maeve (10.1.1.7)
from ssh-gate, which will launch 'umlsh'. This will search for your UMLs
and if you have more than UML it will offer a list of UMLs which you can
access. Once you've picked the UML, you can select a console and it will
switch to it. If you only have one UML, it will switch to that
automatically and if that UML only has one console which can be accessed
via umlsh, then it will also pick that automatically. Thusly, if you
have one UML with one console, it will attach to that console without
interaction. If you want to exit from your attached console you can do
'Ctrl-A q', meaning that you do Ctrl-A, leave go, then press the 'q' key.
From a functionality point of view umlsh is complete, although I will
be working on the UI and some other internals over the weekend before
making a release of umlsh as part of UMLd.
