Strange thing with network interfaces

[tparnet]

tparnet,
why dont you start iwconfig in the script then you could choose which interface. example

#!/bin/sh
iwconfig
echo "Choose Interface"
read iface
clear

now in your script change eth0 or wlan0 to $iface
ifconfig $iface up
now it wont matter if your interface changes.

Didnt even think about that. Thanks Baxter!

Thanks for reply.
Previously I was using Fedora and when I booted it, I always got the same numbers for each interface. So I suppose there must be a reason why it happens on BackTrack.

Edit:
Finally I made this thanks to the link in post above from Funnyman. It was not exactly the same in my case, but quite similar.
So to keep the numbers of your network interfaces the same with every boot, open that file /etc/udev/rules.d/network-devices.rules in editor (in my case it's kwrite).

kwrite /etc/udev/rules.d/network-devices.rules

There should be several lines like that one

#KERNEL=="eth?", SYSFS{address}=="00:11:22:33:44:55", NAME="eth0"

Then just uncomment (remove # mark at the beginning) the line which contains MAC of your network card.
You can also change the name of the interface into "eth1" or "wlan0". It's up to you. After that the line should look like that one.

KERNEL=="eth?", SYSFS{address}=="00:11:22:33:44:55", NAME="eth0"

Many thanks to Funnyman for the link.

I'm happy to help
