I got the opensshd server/client setup last night and woke up this morning reading my event viewer and it was being blown up by a Chinese IP address for exceeding unauthorized attempts lol
Im headed to Best Buy now to purchase a wifi outlet, they are expensive there but I guess it's the same as if I did next day air
If you want to open the ssh port on your router, for security you should change the default port, disable password authentication in the sshd_config file and create an AllowUsers with only public key authentication.
