/etc/udev/rules.d/ contains empty files?


Hello fellas,

I've been reading one book, and i got to the part where in /etc/udev/rules.d i should amend some NIC settings, thru those rules files.

I have the following files in /etc/udev/rules.d*/

70-persistent-cd.rules
73-special-net-names.rules
73-usb-net-by-mac.rules

and all 3 files are empty. This doesn't make any sense, please help.

Hi Nick094 - Welcome to LQ.

You don't mention which linux distribution you're using, so I'll hazard a guess that those files are either meant as examples of titles that could be used or they could be files that were previously created but are no longer used ...

.. or maybe some entirely different explanation.

Best would be to provide some further basic info:

- Describe your hardware

- Identify the version (distribution) of linux that you are using

- Are you the person that installed and configured the OS on this system ? Are there / have there been other users of the system ?

- What behaviour are you hoping to control for the NIC you mention ?

Cheers :-)

Thanks Rickkkk,

Yeah, I figured out that I should provide more info, sorry about that.

I have Kali Linux, installed on VM. It's me who installed it, and i'm the only person using it. I have connection on my Linux so i thought there should be at least some info written down in that 73-special-net-names.rules file.

My OS is win8.1. Please advise which hardware info do you need.

I'm a noob when it comes to Linux so you might have to draw me things.

Here's what I need to do:
Let’s imagine that you recently added a PCI Express network interface card (NIC) to your
system. Because it’s new, udev assigned it the name em1 rather than em0 (the name used
by your existing integrated NIC). The problem is that you’ve hard coded em0 into various
scripts and programs, so they all expect to find a working interface with that name. But
as you want to connect your network cable to the new interface, em0 will no longer work.
Since you’re far too lazy to update all your scripts, how can you edit a file in the /etc/
udev/rules.d/ directory to give your new NIC the name em0?

Many thanks

Networking is disabled by default in Kali. Kali is an advanced distro, designed for those who already know how to use it.

Hei Nick094 - thx for the info.

This question of network interface names comes up regularly. A quick web search turned up the following link which you may find useful:

https://www.cyberciti.biz/faq/howto-...ed-using-udev/

Just a note - on my own system, the file :

Code:
/etc/udev/rules.d/70-persistent-net.rules
...doesn't exist. If you don't yet have it on your Kali system either, I would simply create it and add the line referenced in the above link, obviously substituting the details for your PCIe card.

.. Let us know how you manage - feel free if more assistance is required.

Cheers !

If Kali is using systemd, try this: https://www.freedesktop.org/wiki/Sof...nterfaceNames/
