For the ability to ssh from any client machine, without having

Or is there a more secure way to get this convenience?

Hey Fred,

You could also add the fail2ban package, which reads the SSH logs for authentication failures and bans the offending IP after a specified threshold is reached. This package depends on a package like Shorewall or the like to do the IP blocking.

There are also some best practice notes you might want to review:

Hope this helps.
