Hello. I'm totally new to Linux and backbox is my first foray into the Linux stuff, so please understand if I ask stupid question.

I have machine running windows 7.
I installed virtual box.
I download backbox-3.13-i386.iso.
I set up virtual machine using backbox-3.13-i386.iso on my c:\ drive

Backbox seems to boot up normal and I'm learning my way around. Very nice. However, when I try to use wpscan, I receive the following error:

command:
backbox@backbox:/opt/backbox/wpscan$ ruby wpscan.rb --url www.[mydomain].com/thisfolder/

error:
wpscan.rb:9:in 'delete' : Permission denied - /opt/backbox/wpscan/log.txt (Errno::EACCES)
from wpscan.rb:9:in 'main'
from wpscan.rb:378:in '<main>'


Any ideas what could be causing this and how to fix? Is it because I am running in virtual box and using ISO with the [live cd/dvd] box setting checked in VirutalBox settings? I cannot figure out how to fix. Thank you for your time.

Thank you sir for your response. How do I run this in root?

I click [file system] icon.
I click [opt] folder.
I click [backbox] folder.
I right-click [wpscan] folder and click properties.
I click [permissions] tab.

Owner: root (root)
the other options are greyed out. Is this because I am running off of ISO file in VirtualBox?

Ok thank you again zerof. You have been kind and I appreciate your canter. Your instructions worked like a charm.

Can you perhaps point me to the right learning place for the basics? I google the info and so many links and tutorials pop-up it is difficult to know where to start. I am wanting to learn and also purchase a new laptop that can be dedicate to Linux. Thanks!
