Linux Mint Network Configuration

Linux Mint Network Configuration – Almost all of us have encountered proxies in our work environment. Sometimes these are useful (providing security and firewalls), and sometimes they’re just a pain. For example, at my workplace, I have to go through a squid proxy. In this tutorial, I’ll show how to set up a Linux Mint/Ubuntu (and possibly other distros) computer to get an “internet connection” from behind a proxy. By “internet connection”, I mean getting the synaptic package manager (or apt) and other applications (like browsers) to send HTTP requests through the proxy. Let’s get to it.

There are actually two places where you have to set the proxy hostname, port and username/password (if any). First, go to “System Preferences” and select “Networking”. Select “Network Proxy” on the left side of the list.

Slide the Proxy On button to the top-right. Select “Manual” from the drop-down menu below and enter your proxy host name and port in the corresponding fields. Finally, hit near the bottom. Now you can browse the internet through your browser. It will ask for username and password (if your proxy server requires them) each time.

But surprisingly, Synaptic Package Manager does not use this proxy. To make it work behind a proxy, that is, to be able to install applications from the Internet or update your system, you need to install a proxy for Synaptic as well. To do this, go to “Administration” and select “Synaptic Package Manager”. Click on the “Settings” menu and select “Preferences”. In the new window, select the “Network” tab.

Under “Proxy Server”, select the “Manual Proxy Configuration” radio button, enter your proxy host name and port number in the appropriate fields. If your proxy requires authentication, click the “Authentication” button and enter your username and password. Click OK/Apply. To check if Synaptic is using your proxy settings correctly, press the “Refresh” button. If all goes well, your repository list will be updated.

That was it. You can now install applications from various repositories, update your system and browse the Internet from behind a proxy using Synaptic. I hope this helps. 🙂 Thank you for reading

So, in DHCP, each device is assigned a unique number that allows it to interact with other networks, and as a result, your device’s IP address may change from time to time.

But sometimes you need a static IP address, and need to keep the same IP address for a long time. For example, if you configure your system to be a server, a static IP is necessary for communication purposes. You need to make sure that your computer’s IP address never changes if you want people to download files from it. Also, static IP is necessary if you want to access an external shared device such as a printer.

It is quite simple to configure static IP on your Linux Mint OS through this method, and for this, you need to select network settings from the menu and click on the network icon as shown below.

After going to network settings, you will see the basic details of your currently installed network and the IP address assigned by the DHCP network. So you can change it to a static IP address by clicking on the settings tab available at the bottom left.

After selecting the manual option, it will ask you to enter the new network settings you want, as shown below. You need to enter the value and then click the Apply button to apply the settings. IP address 192.168.114.100 will be static IP, also set netmask and gateway.

Now you need to go back to the main Network Settings window to see the newly applied settings.

You can also configure static IP using the command line interface (CLI), and for this you need to enter the command:

This will open a new window with various options, and then you need to select the first one, “Edit Connection” to apply the new settings which can be seen below.

The next step is to change the “IPv4 Configuration” from automatic to manual, and you need to provide the necessary details to do this.

The first option is used to change your network settings, and the second option of “Activate Connection” is used to apply the settings. You need to open it, click the “Deactivate” button, and then “Activate” it again, which will restart your network so that the new settings can be applied.

So if you want to verify whether the new network settings have been applied, you can do so by typing the following command in the terminal.

You can see from the image above that the newly applied IP address is currently active and working as you can see on the “ens33” field, which is a network interface where IPv4 information resides.

You can also set static IP by making some modifications in the network configuration file and for that, you need to open this file with your favorite editor:

From the above command, we use a nano editor, and after opening the file, you need to write some lines as mentioned below, and after that, you need to save the file.

You should now be able to access your newly applied network settings and confirm it by typing again.

Your Linux Mint operating system is configured for DHCP by default, which means that your machine’s IP address can automatically change to another accessible IP address. However, there are times when you need a static IP address, such as when communicating with a server. So, this is where static IP comes into play; With this, your IP address will not change automatically and will remain the same until it is changed by someone else or returned to DHCP. OpenVPN is a popular open source cross platform VPN protocol. Of all the platforms, Linux has the most possible ways to install and run an OpenVPN client or server. there are many

From Linux out there (eg Mint, Ubuntu, Debian, Fedora, CentOS, Arch) to name a few of the more popular ones. The biggest difference between many Linux distributions is how they handle package management, but almost all distros are capable of installing directly from source code.

And compiling directly from official source code. The biggest advantage is that you can be sure that you are using a binary that has not been compromised by any back doors. However, most distros have safeguards in place to ensure that their official packages can be trusted. However, nothing is fool proof and when working with a security focused application such as a VPN client or an encryption client, some people prefer to compile their own application from the official source code.

If you’re going to install from source, you probably don’t need my help. This process follows the familiar GNU Autoconf process. But for those of you who have never compiled from source, and are curious, the steps are basic;

For those interested in the process, the OpenVPN wiki entry for building is a good place to start. Most users will probably only want to install the precompiled binary packages from their distribution or their VPN provider’s official repositories.

Whatever your Linux distribution, there is likely an OpenVPN package in your official repositories. Installation will vary from distro to distro. Often the software is slightly modified to match the idioms of your chosen distribution. Often these are minor changes such as configuration or where binary files are installed.

Another nice feature of installing from distro repositories is that most package managers install required dependencies. If you do not have the OpenSSL library installed on your system, your package manager should take this into account when installing OpenVPN for you. Below are some examples, but you should refer to your distro’s documentation on how to install the packages.

Many modern RPM based distros use the Yum front end. For example, to install OpenVPN on CentOS you just need to type “

“And the same on Fedora. If you bought an RPM package and don’t want to use Yam, you can always use RPM.”

After you install the OpenVPN client/server (the binaries are both client
