It would be insecue to do so, handing out far too much information to the whole world. As has been mentioned you could try port knocking-- still not terribly secure but it depends on the level of aversary you are protecting from. You could also just change your ssh port number since most ssh attacks use the standard ssh ports. . > > >> >> >>> The problem is that I will often try to connect from my laptop >>> when it is using an Internet feed that is not the one at work.
