Re: [Nolug] redirecting console?

You can do this. You can configure the kernel to use a serial port as the
console. I've never done it before, but i've seen the option in there
when compiling kernels. So as soon as the kernel boots you start getting
output on the console.... Then wire-up a serial connection (you can use
CAT-5) from serial port on your router to your other box where you run
minicom/hyperterminal/whatever to get access to the console. You should
be able to go at least 30-40m RS232 on CAT5, maybe more, but i've never
tried it. You have to look up the DB9 pinouts for making a null-modem
serial cable (a "crossover" serial cable). I'm using minicom on a linux
box as a console for a headless RS/6000, and it works great, and gives
console access via ssh as a nice side effect. If you try it with linux,
let us know how it goes.

Coincidentally, a 1U server box i'm working on (Intel mobo) has a BIOS
option to redirect the "console" to a serial port.
