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.
