(Under construction) This is an optional step for more security and for networks where there are multiple servers on the network using SSH connections. (In some networking configurations it is difficult for a router to know to which SSH server it should forward port 22 traffic). This method involves changing the port for the SSH (tunnel) traffic.
- Create a new environment variable ASTRO_SSH_PORT:
- Start Menu -> Control Panel -> Settings -> Advanced system settings -> Advanced -> Environment variables
There is also an Astronaut utility that brings up the environment variables:
- Start Menu -> Programs -> Astronaut -> Sessions -> Client Variables -> Environment Variables
A list of the environment variables is displayed, each of which can be changed. For example, if the IP address of the VistA server has changed, you can change the ASTRO_SSH_HOST environment variable that the PuTTY SSH client uses to connect to it. Example:
- -> ASTRO_SSH_HOST -> Edit -> Variable Value: 192.168.56.101
- Note: in this example I am changing the IP address to that of an Astronaut VistA server which I installed within a Virtualbox virtual machine on my computer. (I also have a standalone VistA server on my network, so I change this variable frequently, depending on the IP address or URL of the VistA server I am using at the time.) Obviously, use the IP address (which is displayed at the conclusion of the Astronaut VistA server installation process) or URL of your own server installation.
