If you have a kerberos ticket, you can connect to the serial port
console from any machine (eg, your desktop, iris, noric, etc.).

to connect to serial console:

$ /usr/local/bin/console suncat0006

or use this command if your machine has a private /usr/local :

$ /afs/slac/local/bin/console suncat0006

You will get this message from the console software:

[suncat0006: Attached readwrite on conserv1]

Press enter once. You should see:

-----------------------------------------------------
Red Hat Enterprise Linux Client release 5.5 (Tikanga)
Kernel 2.6.18-194.11.1.el5 on an x86_64

suncat0006 login:
-----------------------------------------------------

That is the linux login prompt on the serial console.

All commands you give to the console software start with
the escape sequence:

Ctrl-e c (Ctrl-e, followed by a 'c')

plus one character (sometimes 2 characters).
You can press ctrl-e c ? to see the possible commands:
