Hi everybody,

I have just installed Backtrack 5 R3 on my laptop, but I can't get networking because I don't have some permission...
I did following:
typed root@bt:~# ifconfig eth0 My IP
It said: File exists
root@bt:~# route add default gw My Gateway
root@bt:~# echo nameserver My Gateway > /etc/resolv.conf
And now I can't run this command because I don't have some permission.

Can someone suggest to me what to do?

Thank's

P.S. Sorry for bad English
