You can configure the network manually, for example if If the network configuration has not appeared in the Debian installation IP addresses or routes change.

  1. Identify the network interface of the OIS system by entering the following command:
    ip address show
  • If your system has only one network card installed, two entries are displayed by default.
  1. Use the name of the entry, which is not indicated by loopback, e.g. ens32.
  1. Edit the file /etc/network/interfaces. The route entries (bottom two lines) are required for SafeDlink or if a route is required for other reasons.
  1. Adapt the specified IP addresses accordingly.
  1. Edit the file with vi /etc/network/interfaces. The file looks similar to the following example:

# This file describes the network interfaces available on
your system
# and how to activate them. For more information, see
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug <network interface>
iface <network interface> inet static
post-up ip route add via dev <network interface>
post-up ip route add via dev <network interface>
#The gateway address is generally the router station of the
FS20 with a SafeDlink.
