There are two methods to assign network configuration to a device on the net. DHCP or static assignment. DHCP is normally set as default. Static configurations usually need IP addresses as well as DNS resolvers plus routing. In this tutorial, we will cover static IP configuration on Debian 7.
- Cloud VPS or Dedicated Server with Debian 7 installed.
- You must be logged in via SSH as sudo or root user. This tutorial assumes that you are logged in as a sudo user.
Step 1: Log in using SSH
You must be logged in via SSH as sudo or root user. Please read this article for instructions if you don’t know how to connect.
Step 2: Find the active network interface
clear && echo $(ip -o -4 route get 22.214.171.124 | sed -nr 's/.*dev ([^\ ]+).*/\1/p')
Step 3: Configure the network interface
In our example, our network interface is eth0 with the following network details:
IPv4 = 192.168.0.100 Netmask = 255.255.255.0 Gateway = 192.168.0.1 DNS 126.96.36.199, 188.8.131.52
Our article will use network interface eth0 and the server details described above. Your server details will not be the same as our article and your network interface name can be different then we use in our article. Use the network interface name you get from step 2.
Edit your network configuration file
sudo nano /etc/network/interfaces
auto eth0 iface eth0 inet static address 192.168.0.100 netmask 255.255.255.0 gateway 192.168.0.1 dns-nameservers 184.108.40.206 220.127.116.11
Apply the changes
sudo /etc/init.d/networking restart
Congratulations, you have now configured a static IPv4 for your Debian 7 operating system.
