How to configure a network in linux
3 ways to configure a network interface in Linux
Mar 10, · From the desktop If you are working with a Linux system using a GUI, you can configure the network interface via an icon in the far upper right of the screen. The function of this icon is very similar to the windows “TV Set” down in the lower right of the screen in Estimated Reading Time: 6 mins. Starting off the first command to learn is ifconfig. ifconfig stands for interface configuration and is the necessary command in Unix\Linux to configure and manage network interface parameters via.
One of the most fundamental and useful tasks is being able to share how to make text all caps in excel, files, and printers across a home network.
As a note, this should work with Ubuntu as well, but I find Linux Mint a bit easier to use and is the reference for this article. There are a few different ways to set up a home Linux network, but the following method is how I setup my desktop and laptops all running Linux Mint. Depending on your connection type, the network manager icon might display an icon with a pair of linked computer for cable connection or an icon with the wireless status for wireless connection. This window will show you all of the network information you will need for the device, including its IP address.
This can cause the network share to disconnect. There are two ways to resolve this:. Each router is different but should have a setting to reserve a specific IP address for a specific MAC address. You need to make sure the IP address for each device is unique. You can use any numbering scheme you like as long as they are unique. After all the information is entered, click Apply and from that moment forward that device will always have the IP address that you manually typed in.
SSH is secure and easy to use. The SSH client software is installed by default, but the server is not. If you want to be able to connect to a specific device, that device must have SSH Server installed. If you never want to connect to a specific device you can skip this step. You will need to set the Firewall settings on each device to allow traffic to come in from the other devices. This will bring up the GUI frontend to the ufw firewall. In this example, IP Now anytime you click on this folder, it will connect to the networked computer and you can access its directory.
Since you saved the password, you will not need to login again, unless the password is changed in the future. Now you can simply repeat the process on the other devices and create the shortcut folder on each one. Whenever you want to share across device, you can connect via the shared folder shortcut providing the other device is on, of course!
Though it involves a few steps, I found this is one of the easier ways to how to batik with glue folders and files amongst my desktops and laptops at home that are all running Linux Mint. What other ways do you use to create a home network? Image credit: By Lars P.

Great tutorial, this is the one stop example to learn ssh basics. Simple and well explained. A few questions… I installed openssh-server to my linux desktop but do I need to configure it at what are my rights as a father And if so how do I do that?
Also I set up static ips on my desktop, laptop, and htpc and they all worked great except for the htpc. It worked immediately after changing it but the next morning after rebooting it when I would open the internet it would never get past looking for the web page I typed in.
I used the static ip of whatever was working on the comp when I typed in ifconfig and then used the dns server provided by my isp on all three computers.

Want to browse the web, watch YouTube, stream video, audio or files? RPM-based Linux distributions using Gnome have several fundamental ways to configure the network interface. I'm describing three ways in this article. All of the configuration methods require the entry of sets of numbers that allow the network interface to operate.
You will need three fundamental pieces of numerical information in order to minimally configure a network interface to work over IPv4 and more if you want to define things like IPv6, hostnames, or DNS servers. This article covers the bare minimum for IPv4. Those three fundamental numerical pieces are:. IP Address: The unique number defining the access point to your network interface.
It has the form: xxx. Gateway: The unique number assigned to the network interface at the "other end of the wire" that your computer must communicate through. Again, it has the general xxx. If you are using a home router, your home router generates this number because it is the gateway through which you communicate with the wider world.
Netmask: The non-unique number that defines the network itself. This number can be automatically generated but is sometimes requested by the method you use to configure the interface. It, too, has the format xxx. In each case, the numbers I use will be real numbers applicable to the system I used to write this article. The installer has automatically identified the one ethernet interface available and selected it for configuration.
What to do in this case? Your network is now configured and your system is connected to your local network and optionally, the internet. If you are working with a Linux system using a GUI, you can configure the network interface via an icon in the far upper right of the screen. Choosing the gear button displays the network numbers that have been assigned still DHCP to the network interface.
The parameters defined in these graphical tools have to live in a file you can see. It is controlled by the network management facility nmcli. The relevant bit of information here is to use DHCP, which is used to collect those three important network numbers.
The important parameter seen below is:. That entry means every time this system boots, it will collect its network information from the DHCP server. Leaving your Linux system with no name means that it gets the default hostname of "localhost. If you have multiple systems with the same name, you can only reference those systems on the network by the IP address and the system name becomes useless.
Edit the file and add the following line:. You can't restart the network using systemctl because network. In version 8, use nmcli to restart the network. You should see the following:.
There are several other ways to set the hostname No need to Google it. You can find that information right here on Enable Sysadmin.
