How to revert the change in the new interface names that uses the mac address to go back to the old fashioned way System.d is here.
We can like it or not; but it is as a matter of fact the standard now in the GNU-Linux world.
This project launched by the Red Hat did overtake the init which is condemned to disappear.
We will not discuss here if it is good or not (because we all know it is one of the worst move made blindly by 95% of GNU-Linux distribution
< just kidding)
Like the dinosaurs, we have to adapt (ups... they did not,. bad example) if we want to survive.
The issue : with
system.d version
197 and above the wifi interfaces could not be named wlan0, waln1 etc... but wlx
XXXXXXXXXXXX, the
X are the digits of the mac address of the interface.
The reasons for this change are explained here :
Predictable Network Interface Names As a matter of fact the new rule (nº4) will be apllied by default when we use a USB wifi device.
Names incorporating Firmware/BIOS provided index numbers for on-board devices (example: eno1)
Names incorporating Firmware/BIOS provided PCI Express hotplug slot index numbers (example: ens1)
Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0)
Names incorporating the interfaces's MAC address (example: enx78e7d1ea46da)
Classic, unpredictable kernel-native ethX naming (example: eth0)
The arguments given are "safety" and "avoid confusion".
Safety : If our firewall ruyles are designed for one interface, if we use several wifi USB interfaces to be connected at the same time, they could be a confusion, what we think is wlan1 is wlan2 and the firewall rules that we designed for one interface wil be used in another one.
The one milion € question is : Who the hell does that?
Confusion : Mac is a unique identifer so we will not be confused...
What confuses me personally is to have write down the whole mac address in my interfaces command lines and it is more easy to me to check with one of the multiple command we have the chipset than to check which mac adress belong to which devices,
I don't know them by heart... do you?
I see no point at all in this change and it is definitely not a choice that simplify the life of the users that use command line. .
Give me back my wlanXNo problem... I found a very easy solution here :
0003276: 73-special-net-names.rules causes all USB wifi devices to follow MAC based namingThanks to
threeway (Kali linux developer) for the trick!
1) Open 73-special-net-names.rules with a text editorYou need rots privileges to edit it.
Use your favorite simple text editor.
Mine is gedit so :
sudo gedit /lib/udev/rules.d/73-special-net-names.rulesIt looks like that ;
2) Coment the last line to desactivate the new rulesJust put a dash at beginning of the line (comment it)
Your file should looks like now like this :
3) Save the changes and rebootNow you have your USB interface named like before:
In conclusion, i would like to say thank you to mister X for this :
Too long for linux...
and users
