I am setting up my home server (Ubuntu Server 17.10) to access from work. I have created a static IP address for it and forwarded a port to it. Due to the answer here: https://askubuntu.com/a/51926/30140 I want to follow the instructions here: https://thepcspy.com/read/making-ssh-secure/ to secure my computer. I add the new user Work, and want to give Work its own key. I need to upload the public key using
My questions are: The user is presumably Work. What do I use for my.host? And, if I assigned port xxxx in the router to the IP address, do I need to edit the above command to reflect that?
