Description

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/dos/http/squid_range_dos
msf auxiliary(squid_range_dos) > show actions
    ...actions...
msf auxiliary(squid_range_dos) > set ACTION < action-name >
msf auxiliary(squid_range_dos) > show options
    ...show and set options...
msf auxiliary(squid_range_dos) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
