Wifi script for my internet! [fixed]

post #1 of 4
Thread Starter 
So I'm too lazy to figure it out and am sure one of you can tell me without researching! Anyways, I want to write a bash script that automatically configures my wpa_supplicant and does a lease for my wifi.

Code:
#!/bin/bash

wpa_supplicant -Dwext -ieth1 -c/etc/wpa_supplicant.conf -B

dhcpcd eth1
This works, but if my wifi changes then I have to manually edit it. It's just a minor pain. What I'm wondering is can I set up a bash script that can set eth1 as a variable, ethX or whatever, and grab the proper ethX value from iwconfig? Basically if the ethX has changed I want it to change the variable in the script according to my system.

If there isn't a reasonable way to do this I'll just end up manually setting my wifi to be wlan or something. It's not loading right, this is the only way I've gotten the keys to work with my wifi card. lol

[edit] The only solution I could do is writhe a c++ program but that's a little bit overkill.

Just did static names, screw bash.

I think you should be able to use some combination of piping iwconfig into sed then into your script?

Edit: You might even be able to call iwconfig from within your script, then execute sed against that variable into a new variable

Cause I have 3 of them and none of them are statically set by default. lol I've got my onboard, another NIC card, and a WiFi card! It goes back to when my onboard started acting up, for some reason the lights stopped blinking and it wouldn't stay active. One day it started working again and has worked since but now I use WiFi.

It's no big deal, I'm just going to manually set it eventually. The problem is eventually, I restart so little that it's not that much of a bother.
