NOTE: When you configure the client VT100 emulation window, set the window or application that is displaying the
redirected Virtual Console to 25 rows x 80 columns to make sure the correct text displays. Else, some text screens may
be garbled.
Edit the /etc/grub.conf file as follows:
1. Locate the General Setting sections in the file and add the following:
serial --unit=1 --speed=57600 terminal --timeout=10 serial
2. Append two options to the kernel line:
kernel ............. console=ttyS1,115200n8r console=tty1
3. Disable GRUB's graphical interface and use the text-based interface. Else, the GRUB screen is not displayed in RAC Virtual Console.
To disable the graphical interface, comment-out the line starting with
splashimage.
The following example provides a sample /etc/grub.conf file that shows the changes described in this procedure.
# grub.conf generated by anaconda
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You do not have a /boot partition. This means that all
# kernel and initrd paths are relative to /, e.g.
# root (hd0,0)
# kernel /boot/vmlinuz-version ro root=/dev/sdal
# initrd /boot/initrd-version.img
#boot=/dev/sda
default=0
timeout=10
#splashimage=(hd0,2)/grub/splash.xpm.gz
serial --unit=1 --speed=57600
terminal --timeout=10 serial
title Red Hat Linux Advanced Server (2.4.9-e.3smp) root (hd0,0)
kernel /boot/vmlinuz-2.4.9-e.3smp ro root=/dev/sda1 hda=ide-scsi console=ttyS0
console=ttyS1,115200n8r
initrd /boot/initrd-2.4.9-e.3smp.img
title Red Hat Linux Advanced Server-up (2.4.9-e.3) root (hd0,00)
kernel /boot/vmlinuz-2.4.9-e.3 ro root=/dev/sda1 s
initrd /boot/initrd-2.4.9-e.3.im
4. To enable multiple GRUB options to start Virtual Console sessions through the RAC serial connection, add the following line to all
options:
console=ttyS1,115200n8r console=tty1
The example shows console=ttyS1,57600 added to the first option.
Enabling Login to the Virtual Console After Boot
In the file /etc/inittab, add a new line to configure agetty on the COM2 serial port:
co:2345:respawn:/sbin/agetty -h -L 57600 ttyS1 ansi
The following example shows a sample file with the new line.
#inittab This file describes how the INIT process should set up
#the system in a certain run-level.
#Author:Miquel van Smoorenburg
#Modified for RHS Linux by Marc Ewing and Donnie Barnes
#Default runlevel. The runlevels used by RHS are:
#0 - halt (Do NOT set initdefault to this)
#1 - Single user mode
#2 - Multiuser, without NFS (The same as 3, if you do not have #networking)
#3 - Full multiuser mode
#4 - unused
#5 - X11
#6 - reboot (Do NOT set initdefault to this)
