Configuring Linux
For SOL operation on the server, you must configure the Linux
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.
Configuring Red Hat Enterprise Linux ES 2.1:
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.
To configure the general Linux parameters for SOL operation when using the Red
Hat Enterprise Linux ES 2.1 operating system, complete the following steps.
Note: Hardware flow control prevents character loss during communication over a
serial connection. You must enable it when using a Linux operating system.
