Hi all, I recently updated sshguard to 1.6.0. In the changelog it mentions improved detection for SSH connections: - - Match SSH login failures with "via" suffix - - Update SSH "Bad protocol" signature This seems to detect when a machine connects to port 22 but doesn't try to login. This is what you might expect your monitoring server to do. As a result, your monitoring server will likely end up on the sshguard ban list like mine did. Make sure your monitoring server is whitelisted in the firewall or that you're using the whitelist functionality that sshguard provides. :-)
