How to change eth1 to wlan0 in fedora

bentheman · 12-16-2010, 03:13 AM

Hello everyone!
I'm pretty new in Linux so I have to ask for your generous help
I recently installed Linux "Fedora" and when I click "ifconfig" I see can see the network card "eth1"
I want to change it to "wlan0", I realized that this is a common enough problem at Fedora, and I read about it a bit on Google but unfortunately I did not understand how to change it correctly.
i'll Say thank's if you will give me the order strictly Consul that allows Linux to change the name of my network card

Thank you all in advance for your help,

Ben

Hi there,

I might be asking something stupid, but: why do you want to change the name of your network card??? If this card is not a wireless device, then being called eth1 sounds perfectly correct. If this card is a wireless device, nothing stops you from connecting to a wireless router with it, even though it is called eth1.

Cheers

Hello bentheman and welcome to LQ,

why do you want to change the name of your device?

The name eth0, eth1, wlan0 and so on are assigned by udev and normally it is not possible (not useful respectively) to change this. You know, wlan0 is the devicename for a wireless-adapter whereas eth0 is the devicename of an ethernet-adapter.

Is eth0 a wireless-adapter? please post the output of

Code:

iwconfig

and

Code:

ifconfig

I want to change the name of the network card to support me in "aircrack"
And when I write "iwconfig"I see:
eth1 and all other settings (currently it is connected to a wireless network)
etho-no wireless extensions
And when I write "ifconfig"I see
eth0 ,mac address, packets, etc.
eth1-MAC address different
Last"lo" which listed some of the things :
Link enca: local loopback
inet addr: 127.0.0.1 mask: 255.0.0.0
ands some more..
Thanks for the quick response

I think you have both a built in nic (shown) and a wireless )that is not currently working.)

Ok.. I don't really know if this works, but you could change the DEVICE section in your

Code:

/etc/sysconfig/networking/devices/ifcfg-eth1

But I can not guarantee that it works, I don't use wireless much myself, but you can try and see if it does something, I belief that this section sets the name of device but I might be way off.

It's easy to change it back if it doesn't go as hoped.

Udev sets the device name as mentioned. You can have udev set it as you like.

Edit /etc/udev/rules.d/10-network.rules

Code:

SUBSYSTEM=="net", ATTR{address}=="ff:ee:dd:cc:bb:aa", NAME="wlan0"

Replace the address with your MAC address, and use lower case.

Hi ,
i have tried this code : /etc/sysconfig/networking/devices/ifcfg-eth1
but the answer was : "bash:/etc/sysconfig/networking/devices/ifcfg-eth1:no such file or directory"
and about what reed9 Wrote, i didn't understand ,
as i mentioned above I'm pretty new with Linux

These are all text configuration files. You can edit them with any text editor.

This

Code:

/etc/sysconfig/networking/devices/ifcfg-eth1

Is a path to a location, like C:\Documents and Settings\User\Photos\bob.jpg would be for example in Windows. (Except the above leads to a text file not a photo.)

You need to be root to edit system configuration files. A handy command line text editor is nano, which should be installed by default, so you could open the file as so

Code:

su -
nano /etc/sysconfig/networking/devices/ifcfg-eth1

The su - logs you in as root.

Same with the other

Code:

su -
nano /etc/udev/rules.d/10-network.rules

And put in the line

Code:

SUBSYSTEM=="net", ATTR{address}=="ff:ee:dd:cc:bb:aa", NAME="wlan0"

Where the ff:ee:dd:cc:bb:aa is your MAC address (but use lower case). Save the file and it should now name your interface wlan0 after rebooting.

i'd love opinions ,

Thanks again!!

1. You forgot closing quotes on your mac address. 2. I mentioned before, you need to use lower case letters for the mac.

bentheman · 12-22-2010, 01:04 AM

did it ,
i saved the file , and restarted ,
but nothing changed :/

Did you rename the interface script file? /etc/sysconfig/network-scripts/ifcfg-eth1 --> /etc/sysconfig/network-scripts/ifcfg-wlan0
mv /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/sysconfig/network-scripts/ifcfg-wlan0

Within /etc/sysconfig/network-scripts/ifcfg-wlan0 you should have the top line read: DEVICE=wlan0

And the /etc/udev/rules.d/10-network.rules should have: NAME="wlan0"

After all of that reboot
