(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.

Changing Windows environment variables and shortcuts
- 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.
- -> System variables: New... ->
- -> Variable Name: ASTRO_SSH_PORT
- -> Variable Value: 22144
- Although in this example I used the value 22144 (instead of the default value 22) for the SSH port, obviously this is the (somewhat arbitrary) value that is going to be chosen as your private SSH port.
Change Astronaut SSH shortcut
The "Astronaut SSH" shortcut that is used to invoke the PuTTY SSH client uses a command line:
"C:\Program Files\VistA\Putty\putty.exe" -ssh -l %ASTRO_SSH_clientID% -pw %ASTRO_SSH_CLIENT_PASS% -L %ASTRO_PORT%:127.0.0.1:%ASTRO_PORT% %ASTRO_SSH_HOST%
This must be changed to add the additional variable:
"C:\Program Files\VistA\Putty\putty.exe" -ssh -l %ASTRO_SSH_clientID% -pw %ASTRO_SSH_CLIENT_PASS% -L %ASTRO_PORT%:127.0.0.1:%ASTRO_PORT% %ASTRO_SSH_HOST% -P %ASTRO_SSH_PORT%
If using a manual configuration (for protected environments or on a USB drive, for example) the revised Astronaut SSH shortcut would be similar to:
"C:\Program Files\VistA\Putty\putty.exe" -ssh -l client9260 -pw not#1sostrong -L 9260:127.0.0.1:9260 192.168.56.101 -P 22144
Change Text client shortcut
The "Text client" shortcut that is used to invoke the Text client uses a command line:
"C:\Program Files\VistA\Putty\putty.exe" -P 22 %ASTRO_SSH_HOST% -l %ASTRO_textID% -pw %ASTRO_TEXT_PASS%
The revised Text client shortcut would therefore be:
"C:\Program Files\VistA\Putty\putty.exe" -P %ASTRO_SSH_PORT% %ASTRO_SSH_HOST% -l %ASTRO_textID% -pw %ASTRO_TEXT_PASS%
If using a manual configuration (for protected environments or on a USB drive, for example) the revised Text client shortcut would be similar to:
"C:\Program Files\VistA\Putty\putty.exe" -P 22144 192.168.56.101 -l text9260 -pw not#1sostrong
