Good security is like an onion. The users' think it smells... No, it's layered. Changing the the sshd port from the default does add a layer, a thin layer, but a layer all the same. The rate limiting is a somewhat thicker layer. I personally prefer to block all ssh traffic from the internet and have my customers vpn to my server which let's me ssh over the vpn to their machines. If they happen to have dynamic addresses, it doesn't matter to me. Patrick wrote: > Brian Mathis wrote: > >> @James: >> As for the "security through obscurity" post, you are missing the >> point.
