I always thought -P, but reading the man page, I'm not so sure :( At boot up time if you want output to go to the console, hit F1 as normal, and then at the booting prompt hit the space bar, and then enter in -h and enter. It will then go to the console as normal. ---Mike ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: Enabling Serial Console
Wish to enable the serial console on my servers so that I can remotely view a reboot when it crashes ... I know to plug the serial cable into COM1 ... and I know I have to add something to /boot.config, but, if I want to set it so that even if the keyboard is plugged in, the serial console works, what do I need to add? I always thought -P, but reading the man page, I'm not so sure :( I believe what you are looking for is: # echo '-h' /boot.config Also ... I'm going to cross-connect the servers for now ... ServerA/COM1-ServerB/COM2, ServerB/COM1-ServerC/COM2, etc ... what happens if all machines come up at once? I see nothing in the man page about 'detecting serial', so I'm assuming that the serial console will still work, even if there is nothing at the other end 'listening' yet? Thanks ... Marc G.

Re: Enabling Serial Console
Marc, Try putting either '-h' or '-D' in /boot.config. I found '-D' worked for me. Personally, I'm wondering if I can put together a serial multiplexer to USB device and write a C or Perl script that will tee the output to respective files that I can 'tail -f' on. For a more thorough treatment in a non-intuitive place checkout the Handbook: http://www.freebsd.org/doc/handbook/serialconsole-setup.html Alex On Sep 3, 2004, at 10:18 AM, Marc G.
