sometimes headless server...

radiodee1 · 01-07-2011, 07:30 AM

I'm using squeeze and grub2, and I want to make a server that is sometimes headless, and sometimes has a monitor connected.

I added this line to my inittab file:

Code:

s0:2345:respawn:/sbin/agetty -L -f /etc/issueserial 9600 ttyS0 vt100

and this to my /etc/default/grub file:

Code:

GRUB_TERMINAL=serial
GRUB_CMDLINE_LINUX="console=ttyS0,9600"
GRUB_SERIAL_COMMAND="serial --unit=0 speed=9600 --word=8 --parity=no --stop=1"

now when I boot I get a text style grub screen and the boot up text goes to the serial connection. So far so good. The problem is that I want to see the boot up text on the monitor AND have it go to the serial connection. Is there a way to do this?

Yes. Use multiple console arguments.

Code:

console=tty0 console=ttyS0,9600

I have been away. Sorry for replying so late. Unfortunately this doesn't work. What I get is grub's boot up messages on the serial line, and then the system's start up messages on the serial line too. I googled and all I came up with is AlucardZero's suggestion. Is anyone else doing this? I'd like to be able to see the progress of an fsck check weather or not I'm looking at a serial terminal or a monitor.
