Lovely, thanks Jan. This is just what I needed (the boot option). Thanks for the extra info too, always good to get a better understanding.

I want to attach to the output stream of an existing terminal. I want to "tee" that output to the serial device so I can send it to another machine that will log and save the output. The terminal in question is created and started by "the system". It is acutally /dev/tty10, and is receiving log messages about kernel activity.

One or more of these: * Boot with `console=ttyS0 console=tty0` to copy kernel messages to both ttyS0 and the regular console. This should DTRT for Oops and Panics * use net console And optionally: * configure syslog to write to both ttyS0 and tty10 (if you need that)

Other option suggested was to take a photo of the screen, but the messages disappear off the top of the page (due to the recursive nature of the thing) before I can switch terminals, so this isn't a very useful option.

There exist no recursive panics. What you see must be a recursive oops.

Come to think of it, the last time I had a kernel panic, it was under Solaris, and I used "kdb" to capture it I think (too long ago to remember clearly!) Is there a similar facility in Linux? (Solaris/kdb starts the whole darn kernel under a debugger from the OBP (forth) boot prom prompt).

There is also a KDB for Linux, but I am not sure if it is built into the kernel by default (gives me a compile error blech). -`J' -- ____________________________________________________________________________________ Do you Yahoo!?
