2 Boot the system using "Wake on LAN", as described in Section 4.3.7, "Wake
on LAN" (page 75).
3 Enter root at the Rescue: prompt. A password is not required.
Once you have entered the rescue system, you can make use of the virtual consoles that
can be reached with Alt + F1 to Alt + F6 .
A shell and many other useful utilities, such as the mount program, are available in the
/bin directory. The sbin directory contains important file and network utilities for
reviewing and repairing the file system. This directory also contains the most important
binaries for system maintenance, such as fdisk, mkfs, mkswap, mount, mount, init, and
shutdown, and ifconfig, ip, route, and netstat for maintaining the network. The directory
/usr/bin contains the vi editor, find, less, and ssh.
To see the system messages, either use the command dmesg or view the file /var/
log/messages.
Checking and Manipulating Configuration Files
As an example for a configuration that might be fixed using the rescue system, imagine
you have a broken configuration file that prevents the system from booting properly.
You can fix this using the rescue system.
To manipulate a configuration file, proceed as follows:
1 Start the rescue system using one of the methods described above.
2 To mount a root file system located under /dev/sda6 to the rescue system,
use the following command:
mount /dev/sda6 /mnt
All directories of the system are now located under /mnt
3 Change the directory to the mounted root file system:
cd /mnt
4 Open the problematic configuration file in the vi editor. Adjust and save the
configuration.
