With the SystemRescueCd, you will be able to use the network. Here is the most important information about the network.
If your system has supported hardware, the Ethernet or Wifi network adapter should be automatically detected, and the driver loaded. The interface needs to be assigned an IP address and a default gateway.
SystemRescueCd uses Network-Manager as the default network configuration tool.
It provides a very user friendly graphical interface to configure the network.
It makes the configuration easier especially for wireless networks. For
instance, wireless networks will be automatically detected and connecting to
them is very easy. The Network-Manager is available as a small icon in the
taskbar just next to the clock. It also provides
nmtui if you
want to configure the network using a command line or a semi-graphical interface
from a terminal.
You can also configure the network with other tools such as the standard
ip commands. In that case you will have to stop the
Network-Manager service first, else it will conflict and you will loose your
settings. You can stop it by running
systemctl NetworkManager stop
in the shell.
The following sections of this chapter explain how to use the network using Linux commands. You do not have to read it if you prefer to use the Network-Manager.
Since version 6.0.4 SystemRescueCd comes with the iptables firewall enabled to
block incoming connections requests by default. You need to update the iptables
configuration or stop the iptables and ip6tables services if you need to be able
to receive incoming connections from outside. You can boot SystemRescueCd using
nofirewall option on the command line if you need the firewall to be
To use dynamic configuration,
dhclient eth0. Use
ifconfig -a to
display the IP address the DHCP server leased to the interface.
To assign a specific static IP address, enter something such as:
ifconfig eth0 192.168.10.17. Next the default route is configured. For
example, for an interface at address 192.168.10.17 connected to a gateway at
route add default gw 192.168.10.2.
network boot options
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. It can
be very useful if you plan to make custom version of the rescue system.
Read the chapter about Basic IP configuration tools on Linux for details about how to configure TCP/IP from the command line on a machine running Linux.
SSH allows you to use a shell on another computer (as telnet does), and you can
copy files (with scp or rsync over ssh). If you want to run an SSH server, you
have to change the root password. Just type
passwd and give a valid
password. You can also use the
rootpass=xxx boot option before SystemRescueCd
starts to define the root password.
The ssh server is automatically started but you can type the following command
systemctl sshd restart. You can stop it with
systemctl sshd stop
Of course you can also use SystemRescueCd as an SSH client to connect to an SSH
server: just use
ssh firstname.lastname@example.org or
scp source dest. Both
source and dest may be local or remote. Use
for remote files.
SystemRescueCd comes with the smbfs/cifs client package that allows you to
connect to a Windows machine having shared drives. In recent kernels, support
smbfs has been replaced with
cifs so you should try not to use
The mount-cifs package allows you to access a Windows computer on the network.
Here is an example to explain how to access Windows shared folders. Let’s
consider the Windows box is on 192.168.10.3 and has a shared directory called
mydata accessible by the user called
mkdir /mnt/windows mount -t cifs //192.168.10.3/mydata /mnt/windows -o username=robert,password=passwd cd /mnt/windows
Now you should be able to see files in
/mnt/windows. Do not forget to
unmount the directory when you have finished what you are doing in the shared
If you want to access files located on an FTP server, there is a new very
powerful way to do this. The “Userland FileSystem” allows you to mount the share,
and work on the remote files just as you would work on any local files. With all
these file systems, you can umount the share with the standard umount command.
Here is an example showing how to mount an FTP file system in
as anonymous (read only)
mkdir /mnt/ftp lufis fs=ftpfs,host=ftp.kernel.org /mnt/ftp -s cd /mnt/ftp umount /mnt/ftp
Here is an example of how to mount an SSH file system in
anonymous (read only)
mkdir /mnt/ssh passwd root sshfs email@example.com:/path/to/dir /mnt/ssh cd /mnt/ssh umount /mnt/ssh
