Re: SSH attacks - anyone else seen these?

See the DenyHosts script for the response - this has been going on for years. There's no specific vulnerability, it's more a strength in numbers / worm like attack. The automated attack guesses right often enough to propagate and presumably build a *nix based botnet.

Did anyone else notice similar things? Does anyone know what vulnerability
they are attacking?
