Networking - Assign static IP Address for a FileWave Appliance

Debian Linux

Changing the IP address in Debian 12, which uses systemd-networkd for network management, involves different steps compared to CentOS. The following guide is tailored for Debian 12 servers using systemd-networkd but you could also use Webmin on your server assuming the server comes online initially with DHCP.

For Webmin know that you will need to go to Webmin -> Webmin Configuration -> Operating System and Environment and make sure it's set to Debian 12.4 (Or whatever version we are at when you set up your system. You can see this with cat /etc/debian_version on the server.

1. Locate Network Interface:
   

   First, identify the network interface you wish to configure. You can list all network interfaces using:
   

   networkctl list

   

2. Configure Network Settings:
   systemd-networkd uses individual .network files for each network interface, located in /etc/systemd/network/.
   

   Create or edit the network configuration file for your interface, named like 10-eth0.network (replace eth0 with your interface name).

   sudo nano /etc/systemd/network/10-eth0.network

3. Configure IP Address:
   In the .network file, add or modify the following sections:
   

   [Match]
   Name=eth0
   
   [Network]
   Address=192.168.1.100/24
   Gateway=192.168.1.1
   DNS=8.8.8.8
   DNS=8.8.4.4
   LinkLocalAddressing=no
   IPv6AcceptRA=no

   Replace eth0 with your actual network interface name.
   Modify the Address with your new IP and subnet mask (e.g., /24 for a 255.255.255.0 netmask).
   Set the Gateway and DNS entries as per your network configuration.
   
   You'll also want to edit /etc/network/interfaces because ens192 is configured there for DHCP. That's how you might have gotten to it via Webmin for instance. Edit the file to put a # before the 2 lines that have ens192 on them. Those 2 lines in the file will look like this after editing:
   
   

   # The primary network interface
   #allow-hotplug ens192
   #iface ens192 inet dhcp

   
   

4. Reload and Restart systemd-networkd:

   After making changes, enable the Networkd service so interfaces come up at boot time, and reload the daemon and restart the network:

   sudo systemctl enable systemd-networkd
   sudo systemctl daemon-reload
   sudo systemctl restart systemd-networkd
5. Verification:
   

   Check the status of your network interface to ensure the new settings are active:

   networkctl status eth0

   You can also use ip addr show eth0 to view the IP configuration.

Depending if you are using the appliance we offer for a CentOS Linux virtual appliance or a Linux machine you built the steps may be slightly different. The steps shown below will be for the FileWave virtual appliance that we offer.  

1. Configure the "ifcfg-ens160" file on the server. (This file will be different if you are not using our Virtual Appliance and will have a different name like "ifcfg-eth1" for example)

   vi /etc/sysconfig/network-scripts/ifcfg-ens160

2. Change/add the following values of the file.

   1. Change BOOTPROTO=none

   2. Add "IPADDR", "NETMASK", "GATEWAY", "DNS1" to the file with your network configurations. I attached a screen shot of a completed file below. (If you want to add more then one DNS server you can add DNS2, etc to the file)

      

   3. Save the file using "esc" then ":wq"

3. Now you will need to restart the network services on the server.

   /etc/init.d/network restart
