I need something that can scan my network for Linux machines and then log in to anything it can find and check configs to make sure everything is set up correctly, eg things like that ssh settings are correct, smartd is configured and enabled (if physical machine), no blank passwords, permissions on sensitive config files, etc. This is more of an automatic check of the install process than a tripwire to check for malicious reconfiguration (I just found a machine with a failed harddisk on which I hadn't enabled smartd!)
