Pre-requisites

Before installing Netstat on Debian, make sure that you have an active internet connection and a user account with “sudo” privileges.

Check if already installed

Before diving into the installation process, let’s make sure that it’s not already installed with your Debian 12. You can quickly determine this by opening a terminal window and executing:

$ netstat

If Netstat is installed, you’ll see a list of active network connections, routing tables, and interface statistics displayed in the terminal. However, if you receive an error message indicating that the command is not found, as below:

It means that Netstat isn’t installed on your system. In such cases, fret not, as we’ll guide you through the installation process step by step.

Installing netstat

Now that we’ve established that you don’t have netstat Debian installed, you can proceed with the installation. It’s a pretty straight-forward. In your terminal, run the following:

$ sudo apt install net-tools -y

Netstat will be installed with the “net-tools” package. 

Verify the installation

Like the first step, you can run the netstat command again to check if it has been successfully installed.

$ netstat

Basic commands of netstat

As we’ve seen with the verification step, when you run the “netstat” command, you will get a list of all the active connections. Now we’re going to look into other options and how can you get more out of netstat.

List out the listening ports

To list the details of all the services queued for connection with the ports, execute the following in your terminal:

$ netstat -l

List out the names of the ports

Continuing from the last example, you need to use the following options with the netstat command to show the details of the ports waiting for incoming connections:

$ netstat -plnt

Display stats

You can easily pull the statistics with netstat using the “-s” option:

$ netstat -s

Display the UDP and the TCP connections

Netstat can pull the details of all the UDP & TCP connections using the “-u” and the “-t” options respectively. 

$ netstat -u && netstat -t

Display the routing tables

Finally, if you want to pull details of the routing tables on your Debian 12, use the “-r” option:

$ netstat -r

Uninstalling netstat

After learning about the usage, let’s look at how you can uninstall netstat from your Debian 12. It is a straightforward process. You can remove it using the package management tool “apt” by executing the following commands in the terminal:

$ sudo apt remove net-tools -y

This command will uninstall the Netstat utility along with its associated files from your system. Additionally, if you no longer need the configuration files associated with Netstat, you can use the command:

$ sudo apt purge net-tools 

This command will remove the configuration files as well. Once the uninstallation process is complete, Netstat will be removed from your Debian 12 system, freeing up disk space and ensuring a clean system state.
