I'm trying to create a monitoring system for a remote machine using an IPMI Serial Over Lan (SOL) console. The remote OS is RHEL 6, the mobo manufacturer is Supermicro.
I've successfully enabled SOL redirection in the BIOS. This allows me to see the BIOS and kernel parts of bootup through an attached SOL console over IPMI.
The result is almost always the same : After making the changes to /etc/grub.conf, /etc/inittab, and /etc/securetty, i can see the grub menu through the SOL console (yay!), but as soon as the OS starts booting, my SOL terminal receives 1 gibberish character, and nothing more.
I'm not exaclty sure which serial port my BIOS are trying to redirect stuff into (ttyS0, ttyS1). Most of the examples use ttyS1, and since the grub menu gets redirected there, i'm pretty confident thats 'correct'
I know the 'terminal types' and baud rates have to match between the BIOS and OS settings. I am consistently using 115200 for baud, but i'm less confident I'm choosing the right terminal type. The terminal type in BIOS is "ANSI", and this gives the coloration i want for the BIOS over SOL. However, for the OS settings, most of the examples use 'linux'; i'm not sure if that's compatible with my ANSI setting. I've tried VT100 for both BIOS and OS, and I still never see anything past the Grub menu (plus, i lose color info for my BIOS over SOL).
Any help is greatly appreciated.
