have a cluster running RedHat 7. What one of nodes in the cluster keeps crushing, because I do some kernel development, ( it seems like I am not developing it right )
When it crashes, I usually loose the opps messages that is shown on the screen.
What I am trying to do is hook up this computer to another node in the cluster through serial port and capture the console messages there.
I have a null modem cable and modified the grub settings similar to this :
title Red Hat Linux (2.4.9-21)
root (hd0,0)
kernel /vmlinuz-2.4.9-21 ro root=/dev/hda6 console=tty0 console=ttyS0,9600n8
initrd /initrd-2.4.9-21.img
So kernel will send the messages to the serial port 0
What I need to know is how to read them from the serial port of the other machine.
more specific question is What terminal emulator to use in RedHat and how to make that emulator to save the info in a file for future analysis.
Thank you very much.
