permission denied,How come?
I've alread install BT4 on my portable hard drive,but how come when I use like "ifconfig wlan0 up", It always show permission denied,I tried "su root" and put in password but failed.
Everything need to be rooted,but I don't have root password,neither my user's password or 'toor' works,help me!
You have not completed the installation. A root account should be created.
Search for the installation video tutorial at the remote-exploit blog.
And please, instead of posting 'help me', search for the information you need first. That's what we do. We are happy to help but our time is also valuable.
'Backtrack 4 installation' google search provides 6.2 million results.
if you have sudo permissions maybe you could try 'sudo su' ...
Show us the exact command you are trying to use.
You should have no problem with:
If you want to switch user to root, then first set a root password:Code:sudo ifconfig wlan0 up
After you've set a password, change to root:Code:sudo passwd
Code:su

I think you need to specify root, or else you just change your own password.Originally Posted by Virchanza
I tested it out right there just to be 100% sure.
If you type "passwd" on its own without specifying a user, then it changes the password of the current user (i.e. the user the "passwd" process belongs to).
Now here's the thing: When you type "sudo passwd", "passwd" gets run as root, so it ends up changing the root password.

Ah! Gotcha. I've always just run sudo passwd root. Guess it makes sense to not need to specify root.
Here's another good one. For ages, I've had the following in my Linux Internet Connection tutorial:
I'm surprise nobody called me on the fact that it doesn't work! You get the following reply:Code:sudo echo nameserver 208.67.222.222 > /etc/resolv.conf
The thing is, the "echo" program gets run as root, but the piping is run as a normal user, hence it hasn't got permission to edit the file. Just now I changed the tutorial so it reads:Code:bash: /etc/resolv.conf: Permission denied
I have to say though I'm really surprised nobody ever complained about it not working... I mean that tutorial page gets about a hundred views a day so I figure someone along the way would have gotten the Permission Denied errorCode:sudo sh -c "echo nameserver 208.67.222.222 > /etc/resolv.conf"
