Conguring Windows for Serial Console Redirection
There is no conguration necessary for servers running the Microsoft Windows Server versions, starting with Windows Server 2003.
Windows receives information from the BIOS, and enable the Special Administration Console (SAC) console one COM1.
Conguring Linux for Server Serial Console Redirection During
Boot
The following steps are specic to the Linux GRand Unied Bootloader (GRUB). Similar changes are necessary for using a dierent boot
loader.
NOTE: When you congure the client VT100 emulation window, set the window or application that is displaying the redirected
console to 25 rows×80 columns to make sure proper text is displayed. Else, some text screens will appear distorted.
Edit the /etc/grub.conf le as follows:
1 Locate the general setting sections in the le and type the following two new lines:
serial --unit=1 --speed=57600
terminal --timeout=10 serial
2 Append two options to the kernel line:
kernel console=ttyS1,57600
3 If the /etc/grub.conf contains a splashimage directive, comment it out.
The following example 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
