Linux configuration: For SOL operation on the server, you must configure the
®
Linux operating system to expose the Linux initialization (booting) process. This
enables users to log in to the Linux console through an SOL session and directs
Linux output to the serial console. See the documentation for your specific Linux
operating-system type for information and instructions.
Use one of the following procedures to enable SOL sessions for your Linux
operating system. You must be logged in as a root user to perform these
procedures.
Red Hat Enterprise Linux ES 4 configuration:
Note: This procedure is based on a default installation of Red Hat Enterprise Linux
ES 4. The file names, structures, and commands might be different for other
versions of Red Hat Linux.
To configure the general Linux parameters for SOL operation when you are using
the Red Hat Enterprise Linux ES 4 operating system, complete the following steps.
Note: Hardware flow control prevents character loss during communication over a
serial connection. You must enable it when you are using a Linux operating system.
1. Add the following line to the end of the # Run gettys in standard runlevels
section of the /etc/inittab file. This enables hardware flow control and enables
users to log in through the SOL console.

2. Add the following line at the bottom of the /etc/securetty file to enable a user to
log in as the root user through the SOL console:
ttyS0

1. Modify the /etc/lilo.conf file:
a. Add the following text to the end of the first default=linux line
-Monitor
b. Comment out the map=/boot/map line by adding a # at the beginning of this
line.
c. Comment out the message=/boot/message line by adding a # at the beginning
of this line.
d. Add the following line before the first image= line:
# This will allow you to only Monitor the OS boot via SOL
e. Add the following text to the end of the first label=linux line:
-Monitor
f. Add the following line to the first image= section. This enables SOL.
