Console Redirection Over Serial on a
Linux-based Server
Caution – Redirecting the console over serial is a procedure intended for advanced
users of Linux only.
You can seriously disrupt the proper functioning of the server or render the server
unbootable if you introduce a problem in the configuration files.
Note – Instructions for console redirection on a Solaris-based server are not yet
available.
Redirecting the console interaction over the serial port allows the user another
method to monitor the server. The goal of these configurations is to configure the
bootloader to redirect its output, pass the kernel the proper parameters, and
configure a login session on the serial port.
This section describes how to configure these options.
The BIOS redirects console output to serial by default (9600, 8N1, no handshake)
until a bootloader program is run from the hard disk drive. The bootloader must be
configured to support the serial console in addition to the keyboard, video, and
mouse (KVM) console.
Two common bootloaders are grub and Linux Loader (LILO).
Caution – Do not edit the working-image section of your configuration files
directly.
Copy the working-image section and paste it within the configuration file. Make
your editing changes to this copied section.
