Notes about Hydra, a network login cracker. This can be used to bruteforce login to a service (that you run!) for which you’ve forgotten the password.
hydra [server] [protocol] -l [username] -P [passwords file] -s [port] -S -v -V
- [server]
- The server e.g. pop3.example.com.
- [protocol]
- The protocol e.g. pop3, smtp, etc.
- [username]
- The login username e.g. me@example.com.
- [passwords file]
- A file that contains line-separated passwords (i.e. a passwords dictionary):
password1 password2 ...
- [port]
- The port e.g. 110.
E.g:
hydra pop3.example.com pop3 -l me@example.com -P passwords.txt -s 110 -S -v -V
