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 2.1 configuration:
Note: This procedure is based on a default installation of Red Hat Enterprise Linux
ES 2.1. The file names, structures, and commands might be different for
other versions of Red Hat Linux.
Complete the following steps to configure the general Linux parameters for SOL
operation when using the Red Hat Enterprise Linux ES 2.1 operating system.
Note: Hardware flow control prevents character loss during communication over a
serial connection. You must enable it when 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.
