The Astronaut SSH tunnel is enabled by default using a *nix login ID of client9260 with a default password of not#1sostrong. It is in the /etc/passwd file. You can change it via the passwd command as root. Make sure that the passwords agree on the client side. It runs with no shell and exist only for client communication.

Changing Windows environment variables and shortcuts

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.

-> Variable Name: ASTRO_SSH_CLIENT_PASS -> Modify...
-> Variable Value: super123duperxyzstrong#%!password
-> Variable Name: ASTRO_TEXT_PASS -> Modify...
-> Variable Value: super123duperxyzstrong#%!password
Although in this example I used the value super123duperxyzstrong#%!password
(instead of the default value not#1sostrong) for the SSH client9260 and text9260 passwords, obviously create your own private password. 

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%

No changes need to be made if you changed the environment variable.

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 super123duperxyzstrong#%!password -L 9260:127.0.0.1:9260 192.168.56.101 

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%

No changes need to be made if you changed the environment variable.

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 22 192.168.56.101 -l text9260 super123duperxyzstrong#%!password

Changing the OpenSSH listening port on the VistA server

  • In brief, from the Ubuntu Server command-line terminal edit the OpenSSH configuration file:
sudo nano /etc/ssh/sshd_config
  • Change the line:
port 22
to the port of your desired SSH tunnel:
port 22144
  • Restart OpenSSH:
sudo /etc/init.d/ssh restart
  • Don't forget to configure your firewall (if any) on the Ubuntu Server to allow the new SSH port (e.g. 22144) through.
