The intention of the case you quoted (opening up the SSH port) is to deter casual portscanners or SSH version scanners. This way, my system is much less likely to be on a list of hosts running SSH servers. After the port is opened up, you get a regular, properly configured, up-to-date SSH daemon. -- Jurjen Oskam _______________________________________________ Full-Disclosure - We believe in it.
