Network Options with SysRescue


This documentation is extracted from the System Rescue CD documentation found on line at Please refer to the original documentation there.

Automatic Network configuration

If your system has supported hardware, ethernet or wifi network adapters should be automatically detected, and the driver loaded during boot. You will still need to assign an IP address and a default gateway.

  • Network-Manager provides a graphical interface to configure the network, which makes configuration easier especially for wireless networks. The Network-Manager is available as a small icon in the taskbar just next to the clock. Network-Manager is only available in the graphical environment.
  • net-setup utility, (e.g. net-setup eth0) should be used on the command line.

Hand-configuring Networking


To use command line tools, first stop Network-Manager by running /etc/init.d/NetworkManager stop in the shell or by booting SystemRescueCd with the nonm boot option. If you are booting SystemRescueCd from the network or if you are using boot options such as ethx or dodhcp the Network-Manager service will automatically be stopped.

  • dhcpd: To use dynamic configuration, type dhcpcd eth0. Then use ifconfig -a to display the IP address the DHCP server leased to the interface.
  • ifconfig: To assign a specific static IP address, enter ifconfig eth0 or similar, depending on the ethernet port and IP desired.
  • route: Next configure the default route. For example, to connect to a gateway at enter: route add default gw

Setting up Networking at Boot

SystemRescueCd provides network boot options such as ethx, dns, gateway, dodhcp that allow you to automatically configure the network when SystemRescueCd starts. It is very useful if you want to boot SystemRescueCd from the network using PXE but it can be used in any case.

Running an SSH Server

SSH allows you to use a shell on another computer (as telnet does), and you can copy files (with scp). If you want to run an SSH server, first change the root password by typing passwd xxx. You can also use the rootpass=xxx boot option before SystemRescueCd starts to define the root password.

Although ssh server is automatically started, you can restart it with the command /etc/init.d/sshd restart, and you can stop it with /etc/init.d/sshd stop. You can also use SystemRescueCd as an SSH client to connect to an SSH server: just use ssh or scp source dest. Both source and dest may be local or remote. Use for remote files.

Accessing a Windows Share

SystemRescueCd comes with the cifs client package that allows you to connect to a Windows machine having shared drives.

The mount-cifs package allows you to access a Windows computer on the network. For example, suppose a Windows box is on and has a shared directory called mydata accessible by user robert:

mkdir /mnt/windows
mount -t cifs // /mnt/windows -o username=robert,MyPaSsWoRd=root -o lfs
cd /mnt/windows

Now you should be able to see files in /mnt/windows. Don’t forget to unmount the directory when you have finished what you are doing in the shared directory:

umount /mnt/windows

It’s important not to forget the option “lfs” (Large File Support), because it allows you to handle files that are larger than 2 GB. Big files are often used when making a backup or an image file.

Mount remote FTP/SSH shares

there is a powerful way to access files located on an FTP server as local file systems with the Userland FileSystem. You mount the share and work on the remote files just as you would work on any local files, then umount the share with the standard umount command. Here is an example showing how to mount an FTP file system in /mnt/ftp as anonymous (read only):

mkdir /mnt/ftp
lufis fs=ftpfs, /mnt/ftp -s
cd /mnt/ftp
umount /mnt/ftp

Here is an example of how to mount an SSH file system in /mnt/ssh as anonymous (read only):

mkdir /mnt/ssh
passwd root
sshfs /mnt/ssh
cd /mnt/ssh
umount /mnt/ssh
