This tutorial shows how to install it in Ubuntu Linux, how it works, and what you can do with this powerful security auditing tool. Under the Module Options section of the above exploit there were the following commands to run: Note: The show targets & set TARGET steps are not necessary as 0 is the default. From the results, we can see the open ports 139 and 445. ---- --------------- -------- -----------

On metasploitable there were over 60 vulnerabilities, consisting of similar ones to the windows target. The example below using rpcinfo to identify NFS and showmount -e to determine that the "/" share (the root of the file system) is being exported. After you have downloaded the Metasploitable 2 file, you will need to unzip the file to see its contents. WritableDir /tmp yes A directory where we can write files (must not be mounted noexec)
Metasploitable is a Linux virtual machine which we deliberately make vulnerable to attacks.
