WEP encryption password


I have a wireless network in my house and ive been running knoppix just fine with it all set up, but recently i put a WEP encryption password on the network, and i havnt been able to figure out how to enter it for my one computer running linux. My other computers are all running windows and it was easy to put the WEP key in. If anyone knows how i can easily just put the WEP key in to get up on the network i would appreciate it, thanx.

If your interface is called eth0 and your key is xxxxxxxxxx hex, you would write type
Code:
iwconfig eth0 key xxxxxxxxxx
If the key is an ascii string some_string, then do
Code:
iwconfig eth0 key s:some_string

If you want to work with a passphrase instead of trying to type in a WEP key you can find a slick little perl script here:

when i type in "iwconfig wlan0 key xxxxxxxxxx" (no quotes), i get errors (my wireless interface is wlan0)

when i type iwconfig, in the little wireless summary that comes up for wlan0, it says Encryption key: off

Do i have to somehow turn that on first, before entering the key

Did you try:

iwconfig device key xxxxxxxxxxxxxx


?


Drop the open and see what happens.

As Berhanie mentioned, are you using a hex key or an ascii key?

Hmmm.... iwconfig is the way to set it. I'm out of possible answers. You'll have to try googling for your wireless card and knoppix and see if someone else has figured out that's up. I would definitely work on getting some kind of encryption to work. It's too easy to fireup kismet and monitor someone's unencrypted network.

I would guess that your driver/card doesn't support WEP. You might consider updating to the latest driver and trying again.
