Debian Live Lenny with live-getty on serial port

[Mark Gannon]

Folks,

I'm trying to build a Debian Live USB implementation based on Lenny. I would
like to redirect the login prompt from VGA to the serial port.

In reading through past posts on the subject, the following boot paramters
should work:

live live-getty console=ttyS0,38400n8

The only content that appears on the serial interface is the console output.
There is never a login prompt.

Thanks in advance for your help.

Regards,

Mark Gannon

Hello,

I'm using debian-live system through a serial port with following
kernel cmdline :

boot=live live-getty [... other options...] console=tty0 console=ttyS1,115200n8

so your system should work. Which live-helper/live-initramfs versions
did you use ? If your system has also VGA output, do you have logins on
virtual consoles ?
Or perhaps your problem comes from your customization ? you could try
to add a ssh server to your live system to connect to it by net and see
what is going on...

hope it helps,
Fred.

Changing my boot paraemeters (based on the above) from:

live live-getty console=ttyS0,38400n8

to:

live live-getty console=tty0 console=ttyS0,38400n8

Changed the behavior so that I now get a shell prompt on the serial port after
the console output appears.

Thanks!

That is odd!
I wrote the original live-getty and auto serial console code.
I have not looked at the current code but if we NEED "console=tty0"
followed by "console=ttyS0,38400n8" for a serial console prompt then
that is a BUG!

Glad there is a work around though!

Yes, I'm agree. I've added "console=tty0" to have *also* console
messages on the VGA port...

I've tried to boot a Debian Live system (latest
live-helper/initramfs) with only console=ttyS1,..., and I get a bash
prompt at the end of boot, as expected.

OK so no bug! Phew!

Thanks for testing and explaining what happens!
Glad it is working as expected.
