Trouble with permissons.

When I attempt to open the social egineer tool kit, i receive this error--Traceback (most recent call last):
File "./setoolkit", line 40, in <module>
filewrite = file("src/logs/set_logfile.log", "w")
IOError: [Errno 13] Permission denied: 'src/logs/set_logfile.log'

[B ]When i tried to install current Adobe Flasher Player plugins i received a similar error "Permission denied."
When i try and run nmap and a few other programs, the db hints that i'm not a root user. I've modified my
sudoers file properly. Even when i user su and attempt to loads these programs through the terminal i get an error.
Futhermore, this is a new install, 8gb flash, burned with unetbutin.[/B]

Any help or direction would be appreciated.

Weird but I think on the kali site they say to not use unetbootin to burn kali. Could be an error caused by that v

Use " sudo " before your command line

without sudo i cannot start nmap>

Code:

---

kcdtv@noname4u:~$ nmap -sS 192.168.0.1
You requested a scan type which requires root privileges.
QUITTING!

---

adding sudo before my order i can use nmap

Code:

---

sudo nmap -sS 192.168.0.1

Starting Nmap 6.40 ( http://nmap.org ) at 2013-09-16 09:08 CEST
Nmap scan report for 192.168.0.1

Or you can start by "sudo su" in your shell and the shell will be established with root privilege all along and you will be able to launch aplications such as nmap, mdk3, aireplay-ng etc... without writing "sudo"

Now you have got it, sudo is your new friend for ever, it is very important and usefull in debian based system such as Kali or XUbuntu, Ubuntu etc...

Thank you for your time guys :)
