console login through RS232/serial port ?

Yalla-One · 02-24-2005, 03:38 PM

How do I configure my RS232/serial port to allow console logins from another machine?

My Linux-server-to-be does not have a keyboard or screen attached, and I'd like to be able to do a console login without running to my neighbour to borrow a screen. (All my other computers are laptops with no video in)

Can I use mgetty for this, or any other software that allows me to do a console login similar to how it's done on Sun machines and Cisco routers?

Thanks much in advance for any insight!

This document seems to describe how to do that: http://www.vanemery.com/Linux/Serial...l-console.html

Perfect!

Thank you so much - now I know what I'll be doing this upcoming weekend

Just a quick newbie question : I see this is for Red Hat, and I run SuSE - are there any obvious changes I should be aware of, or is this pretty standard and straightforward?

SuSE is fairly similar to RedHat (at least from the relatively limited experience I have dealt with both of them), so it is not unlikely that the instructions will apply to SuSE as well.

In Debian which I use it was trivial to enable console login on a serial port, I just tried it to see how well it worked to do so. I just had to uncomment one line in /etc/inittab, and then run init q to reload the inittab settings.

Example how it looks for me there now:

Code:

# Example how to put a getty on a serial line (for a terminal)
#
#T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100
T1:23:respawn:/sbin/getty -L ttyS1 115200 vt100
