1. Enumerating Multiple Hosts at Once
    nullinux provides several options for enumerating users and shares from multiple hosts. Although this can be completed with other tools using a bash loop, nullinux simplifies this process.
   
   
    Bash Loop: x=0;until [ $x -eq “3” ]; do enum4linux 192.168.1.$x; ((x++)); done
   OR
   python nullinux.py -all 192.168.1.1-5
   python nullinux.py 192.168.1.1,192.168.1.7


2. Creates user.txt file of all users enumerated
   By evoking the command line argument “-users”, nullinux will attempt to enumerate users through all available options and display the results on screen. nullinux will compile all users collected during enumeration into a single .txt file, free of duplicates. This nullinux_user.txt file can then be used for password spraying or other internal attacks.
   
   
   Nullinux can also be set to use non-invasive and lengthy techniques to enumerate users through the "-quick" option. This will perform a quick enumeration of users leaving out brute force options such as known usernames, rid cycling, and enumerating the LSA.


3. Dynamic Share Enumeration
   The command line argument “-shares” will attempt to enumerate all available shares on the host and automatically attempt to enumerate the directory of each share found. Simplifying what used to be a very manual process. Both “-shares” and “-users” can be implemented together using the “-all” command line argument.
   
   
   python nullinux.py -shares 192.168.1.1
   python nullinux.py -all 10.0.0.1

Scanning:
    -shares             Dynamically Enumerate all possible
                        shares. (formally: --enumshares)

    -users              Enumerate users through a variety of
                        techniques. (formally: --enumusers)

    -quick              Quickly enumerate users, leaving out brute
                        force options. (used with: -users, or -all)

    -all                Enumerate both users and shares
                        (formally: --all)

Host:
    -U                  Set username (optional)
    -P                  Set password (optional)
