Tethering on KDE Plasma Desktop

Tethering is a fairly common practice using a mobile phone data access to some other device like a laptop or tablet. It is very straight forward to on an Android phone, merely "flipping a switch" in the network settings. I'm sure it is similar on other like devices. Did you know it is possible to tether from KDE Plasma Desktop 5 to another device? It is indeed true and you have several tethering options depending on your hardware.

This feature is not unique to openSUSE but this was done on openSUSE Tumbleweed with KDE Plasma version 5.10.3. This should work on any KDE Plasma 5 installation. 

Why on Earth did you need to do this?

I have, on more than one occasion, performed an install of openSUSE Linux on a computer away from home in a less-than-ideal environment. Unfortunately, there are still some hardware manufacturers that don't directly support Linux and additional 3rd party drivers need to be installed. The only case  wireless cards from Broadcom.

How I did it

Connected each computer from Ethernet port to Ethernet port.

You may see both computers start to auto-negotiate... you don't want the computer sharing the network connection to the recipient as a client. the Network Manager applet, select, configure the network connections...

Since I am sharing the wifi this computer is picking up to a wired connection, I need to configure the Ethernet to share the wireless network access through my wired Ethernet port.

On this dialog, select Wired Ethernet (Shared).
Not much more needs to be done here. I set the connection name to: Tether and restricted it to the single Ethernet port I have available on this machine.
In order to not have this connection automatically activate when I plug into a network, I deselected: Automatically connect to this network when it is available.
Nothing has to be changed under the IPv4 tab, just note that this Method is "Shared to other computers"
You have now successfully shared your network connection. Time to get that wifi driver working on the new machine! Here is a great resource for getting those pesky Broadcom drivers working


This is not something I have had to use very often but it is very handy to have when your options are limited. You can, of course, reverse this process and use your machine as a wireless access point for machines that don't have Ethernet ports like phones or tablets or poorly designed laptops.

There is such a sense of freedom and when you have the ability utilize the capabilities of your hardware such as this with just a few clicks. This is yet another reason why Linux is awesome and especially awesome on openSUSE with KDE Plasma Desktop.
