NAME

       smb-nat - NetBIOS Auditing Tool

SYNOPSIS

       smb-nat [-d <debuglevel>] [-o <output>] [-u <userlist>] [-p <passlist>] <address>

DESCRIPTION

       smb-nat is a tool written to perform various security checks on systems offering the NetBIOS file sharing
       service.   smb-nat will attempt to retrieve all information availible from the remote server, and attempt
       to access any services provided by the server.

OPTIONS

       -o     Specify the output file.  All results from the scan will be written  to  the  specified  file,  in
              addition to standard output.

       -u     Specify  the  file  to  read  usernames from.  Usernames will be read from the specified file when
              attempting to guess the password on the remote server.  Usernames should appear one  per  line  in
              the specified file.  A sample username file can be found at /usr/share/smb-nat/userlist.txt.

       -p     Specify  the  file  to  read  passwords from.  Passwords will be read from the specified file when
              attempting to guess the password on the remote server.  Passwords should appear one  per  line  in
              the specified file.  A sample password file can be found at /usr/share/smb-nat/passlist.txt.

       <address>
              Addresses  should  be  specified  in  comma  deliminated  format,  with  no spaces.  Valid address
              specifications include:

              hostname - "hostname" is added

              127.0.0.1-127.0.0.3, adds addresses 127.0.0.1 through 127.0.0.3

              127.0.0.1-3, adds addresses 127.0.0.1 through 127.0.0.3

              127.0.0.1-3,7,10-20, adds addresses 127.0.0.1 through  127.0.0.3,  127.0.0.7,  127.0.0.10  through
              127.0.0.20.

              hostname,127.0.0.1-3, adds "hostname" and 127.0.0.1 through 127.0.0.1

              All combinations of hostnames and address ranges as specified above are valid.

       If  no  userlist  or  password  list files are specified on the command line, a small set of defaults are
       used.  This list includes the following:

         Usernames

         "ADMINISTRATOR", "GUEST", "BACKUP", "ROOT", "ADMIN",  "USER",  "DEMO",  "TEST",  "SYSTEM",  "OPERATOR",
       "OPER", "LOCAL"

         Passwords

         "ADMINISTRATOR",  "GUEST",  "ROOT",  "ADMIN",  "PASSWORD",  "TEMP",  "SHARE",  "WRITE", "FULL", "BOTH",
       "READ", "FILES", "DEMO", "TEST", "ACCESS", "USER", "BACKUP", "SYSTEM", "SERVER", "LOCAL"

       The password guessing routines are written in such a way that all passwords are tried for all  usernames.
       Keep  this  in  mind  when  using larger lists of passwords and usernames, as the time required increases
       exponentially with the size of these lists.
