Configuring a Static IP Address in Debian using Shell Scripting

As a programmer, it is important to know how to configure a static IP address on a Debian system using Shell Scripting. In this tutorial, we will cover the steps to configure a static IP address on a Debian system using Shell Scripting.

Step 1: Checking Network Interface

Before we proceed with the configuration of a static IP address, we must check which network interface is being used by our system. We will use the ifconfig command to check which network interface is being used.

ifconfig -a

The output of this command will show all the network interfaces being used by the system.

Step 2: Editing the Network Interface File

After we have determined the network interface being used, we can proceed with the configuration of a static IP address by editing the network interface file. We will use the nano editor to edit the interfaces file.

sudo nano /etc/network/interfaces

After opening the file, we will add the following lines to the file, replacing eth0 with the name of the network interface being used and 192.168.1.10 with the desired IP address.

auto eth0
iface eth0 inet static
    address 192.168.1.10
    netmask 255.255.255.0
    gateway 192.168.1.1

Save the file and exit the editor.

Step 3: Restarting the Network Service

Once the network interface file has been edited with the desired IP address, we must restart the network service to apply the changes. We will use the following command to restart the network service.

sudo systemctl restart networking

The network service will be restarted and the system will now be using the configured static IP address.

Conclusion

In this tutorial, we have learned how to configure a static IP address on a Debian system using Shell Scripting. By following these steps, programmers can easily configure a static IP address on their Debian systems, providing a stable and consistent network connection for their development work.
