Encryption and Keys

The Godfather · 09-02-2005, 11:13 AM

Hi

I have set up encryption on my wireless router. However, now I need to type in the key to allow me to connect to it again. Does anyone know how to do this?

I am using FC2, and have looked through all the gui type options from the start menu and cannot find anything of use. I'm asummung (and hoping!) there is a shell program to help me do this.

Thanks for all your help

I'm assuming you are referring to wep. If thats the case

# iwconfig interface key key

If you are using a keyphrase, add a preceeding "s:" to the key.

# iwconfig interface key s:key

All the information goes in your wpa_supplicant file, including psk.

Thanks alot, it all works fine now.

How about connecting an ethernet card to a wireless router via a twisted pair cable, how can I set up the key then? ive tried iwconfig but it returns: no wireless extensions. Is there a similar command that can be applied to ethernet connections?

Thanks

You don't need encryption on a wired connection. The encryption is there because you are broadcasting your traffic over the airwaves, succeptable to be sniffed by anyone in the area. Just setup the card with required information. If it is receiving dhcp, then dhclient -i eth0 (or whatever interface it is).
