Assuming your sshd server is on a computer attached to a router which is your gateway to the internet, and the router is set to forward port 22 to that computer some ISP's don't route port 22 traffic. I know that AT&T blocks port 22 traffic and it gives that message. I set the sshd server to listen on port 26 instead and it works fine. Don MacDougall
