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 If the key is an ascii string some_string, then do

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

what errors do you get?

root@box:/home/Marzig76# iwconfig wlan0 key open XXXXXXXXXXXXXXXXXXXXXXX

Did you try:

iwconfig device key xxxxxxxxxxxxxx


?


Drop the open and see what happens.

same results

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

its a hex key...

at this point, i thinking about just taking the encryption off, but i'm scared about wireless hacking

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.

thanx for the help, the weird thing is that the network worked just fine before i set encryption....anyway, i'll figure somthing out, but if anyone else knows what could be wrong, let me know..thanx

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

well ive used this card on a windows pc and it worked with encryption just fine..also as for the drivers, i am using the linux wlan drivers..and they're updated
