I'm securing my ssh server with DenyHosts, and decided to dig into DenyHosts' configuration to make sure things looked good. There's an option called SERVER_SYNC, that makes an xmlrpc call and seems to crowdsource securing an SSH server by using denyhosts' central server to collect statistics about bad hosts.
I'm intrigued by the idea, but before making such a drastic change I wanted to know, are other people using this? If so, please write a little about your experience with the SYNC_SERVER option in DenyHosts and any issues I should watch for. Thanks.
