anonymous

The ftp/anonymous scanner will scan a range of IP addresses searching for FTP servers that allow anonymous access and determines where read or write permissions are allowed.

Configuring the module is a simple matter of setting the IP range we wish to scan along with the number of concurrent threads and let it run.

ftp_version

The ftp_version module simply scans a range of IP addresses and determines the version of any FTP servers that are running.

msf > use auxiliary/scanner/ftp/ftp_version
msf auxiliary(ftp_version) > show options

Module options:

   Name     Current Setting      Required  Description
   ----     ---------------      --------  -----------
   FTPPASS  mozilla@example.com  no        The password for the specified username
   FTPUSER  anonymous            no        The username to authenticate as
   RHOSTS                        yes       The target address range or CIDR identifier

   THREADS  1                    yes       The number of concurrent threads

To setup the module, we just set our RHOSTS and THREADS values and let it run.
