server hang

[K.C. Chan]

running rh7.2 with kernel 2.4.26. Server hang. Server has blank screen of death. Is there a way to log event into a log file? Thanks.

If you have serial console support in your kernel, you could always use that to try and log any messages that are written to the console and not captured in logfiles.

Yes I have serial console, any idea how to set this up?

Hello K.C.

You say that you already have a serial console configured. Whatever you use for a terminal would determine how you can log console. I typically use TeraTerm Pro

under Windows and minicom
http://alioth.debian.org/projects/minicom/
under linux. Both have the ablity to log a session to a file.

You could even run minicom under GNU screen so that you can detach the session and check it once in a while. If you do be aware that both screen and minicom use ctrl-A for a hot key.

Hope this helps,
Tom

Since both uses hot key ctr+A, then how do I send a ctrl sequence for screen and minicom? I tried ctrl+A z but that puts me into background , it's not what I wanted. I want to access ctr+A,L for logging in minicom. Any idea to distinguish between the two?

all, ignore previous post. I figured how to change meta character "Ctrl A" for minicom to something else. Thanks.
