I have set up a home server using openSUSE 11.2. One of the features I want it to expose is the ability for me to remotely connect to administer it. I installed the FreeNX packages per some instructions on openSUSE's site and have it up and running. I have yet to change my ssh port, but plan to do so perhaps today. Nothing is currently exposed through my router to the outside world: the only access is by another PC in my house. So, my question: is this secure? Aside from obfuscation with changing the port #, do I need to do anything else to make this a secure way for me to connect in to my system from somewhere else on the planet? I have been using the official No Machine client on Windows XP Home to connect so far, and plan to use the No Machine client from either a laptop running openSUSE 11.2, or XP Professional. How can I lock this down in a reasonable fashion? Thanks in advance!!

Software/Hardware used:
openSUSE 11.2, FreeNX

Thanks. We'll let you know when a new response is added.

The short answer is yes, this is a fairly secure connection. It can be made more secure by using any number of additional features within either the sshd service or nxserver service. I’m including a link to a webpage that covers some of these options in better detail than I can. It is not the only good source for this type of information available, but it does give you a lot of information that you can use to decide what, if any, additional methods you would want to use to further secure a connection coming in from the Internet. Good luck with it.
