I am curious as to why DenyHosts is not mentioned in this context (beside fail2ban and sshguard. Is its use deprecated? I ask because I administer about 300 servers with DenyHost grandfathered on the servers. I've googled a bit to see the relative merits and DH is just for ssh whereas fail2ban is more general. I somehow didn't know about sshguard - it looks interesting (and also seems to do more than just ssh brute force blocking). So... do I need to take DH off the herd and replace?
