Hydra is a tool for brute-forcing SSH connections. It is much slower than offline password-guessing with (e.g.) John the Ripper, but sometimes this is your only option.

See the Hydra page for more info.

John the Ripper

John the Ripper is a software suite for password testing. It provides many different functions that make it a good complement to any program.
