| Q | How do I make the NX Client connect to an existing session? |
|
| Q | I like the features of a particular flavor of VNC (or any remote access method) but it doesn't support encryption. What can I do to secure it? |
|
Answers
| Q | A Currently, the most oft used solution is to have the local user use an NX session (to localhost). That way, all of their activities are always within an NX session, making management (terminate, pause, resume) much simpler. Again, it's not elegant but it works adequately. |
| Q | A One of the most common approaches is to use the SSH port-forwarding functionality. This is how many of the VNC variants are providing encryption behinds the scenes anyway. While we discuss gaining administrative access via SSH in this chapter, Chapter 5 (Managing Event Logs) contains detailed instructions on using the SSH port forwarding feature. |
