Basic Usage

This module is a scanner module, and is capable of testing against multiple hosts.

msf > use auxiliary/scanner/snmp/brocade_enumhash
msf auxiliary(brocade_enumhash) > show options
    ... show and set options ...
msf auxiliary(brocade_enumhash) > set RHOSTS ip-range
msf auxiliary(brocade_enumhash) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(brocade_enumhash) > set RHOSTS 192.168.1.3-192.168.1.200

Example 2:

msf auxiliary(brocade_enumhash) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(brocade_enumhash) > set RHOSTS file:/tmp/ip_list.txt
