== Changing environment variables ==

 +
The Astronaut Client installer sets several Windows environment variables. These are used by the PuTTY SSH client, for example, to establish a secure SSH tunnel to the server. These environment variables must be changed from time to time, in case your network or other installation parameters change.
 +
 +
To access the environment variables, follow these steps.
 +
 +
=== Windows 7 ===
 +
See [http://www.itechtalk.com/thread3595.html this tutorial] for step-by-step instructions on editing the environment variables in Windows 7. In short,
 +
 +
: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 WorldVistA server which I installed within a Virtualbox virtual machine on my computer. (I also have a standalone WorldVistA server on my network, so I change this variable frequently, depending on the IP address of the WorldVistA server I am using at the time.) Obviously, use the IP address of your own server installation (which is displayed at the conclusion of the Astronaut VistA server installation process).
 +
 +
=== Securing your installation ===
 +
==== Securing the SSH conection ====
 +
The PuTTY SSH connection is the entry point to your server. You ought to make this connection secure.
 +
 +
* Change the %ASTRO_SSH_CLIENT_PASS%  (either the environment variable or explicitly in the Astronaut SSH shortcuts) to something other than ''not#1sostrong''. This must then also be changed at the VistA server.
 +
 +
* You can also change the %ASTRO_SSH_clientID% and %ASTRO_PORT% for extra security, but this is an exercise beyond this guide.
 +
 +
===== Changing the SSH password on the server =====
 +
(Under construction)
 +
* Read [[Ubuntu_Guide_All#SSH|Ubuntu SSH]] basics for information about SSH and [[Ubuntu_Guide_All#Setup_an_SSH_server|generating/using an SSH keypair]].
 +
 +
==== Securing your administrator password ====
 +
*You should immediately change the administrator (''sys.admin'') password (i.e. Verify Code) from the installation default (''vista!123''), otherwise anyone reading these instructions would know the password of your installation. Duh. You can change this by a variety of methods.
 +
:*Login to the VistA server (in Linux) directly. You will be prompted to change the password the first time. If not, use the command:
 +
sudo passwd ''sys.admin''
 +
:*Login to TMG-CPRS or VistAConfig. The option to change the password at login appears:
 +
:* Change Verify Code: (ticked)
 +
 +
*In reality, you should change all the passwords of the sample users with which Astronaut VistA comes pre-populated, but since these passwords aren't displayed or published (in general), this is not as high a risk nor as immediate a priority.
 +
 +
=== Installing in a protected environment ===
 +
You may wish to install the Astronaut client package on a Windows computer whose access is restricted to certain administrators. The method for doing so is to install Astronaut to the
 +
C:\Documents and Settings\All Users\Application Data\VistA
 +
folder on your Windows machine. This folder is generally not protected (or restricted to administrators) and can then be accessed by all users.
 +
 +
Environment variables may not be able to be changed on the computer by anyone other than an administrator. When installing without administrator privileges, the startup shortcuts must be changed so that environment variables are not used.
 +
 +
==== 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%
 +
 +
The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:
 +
* %ASTRO_SSH_clientID% -> ''client9260'' (this is the default value)
 +
* %ASTRO_SSH_CLIENT_PASS% -> ''not#1sostrong'' (this is the default value)
 +
* %ASTRO_PORT% -> 9260
 +
* %ASTRO_SSH_HOST% -> ''192.168.56.101'' (use the IP address of the installed VistA server)
 +
 +
The revised Astronaut SSH shortcut would therefore be:
 +
"C:\Program Files\VistA\Putty\putty.exe" -ssh -l client9260 -pw not#1sostrong -L 9260:127.0.0.1:9260 192.168.56.101
 +
 +
==== Change TMG-CPRS shortcut ====
 +
The "TMG-CPRS" shortcut that is used to invoke the CPRS client uses a command line:
 +
"C:\Program Files\VistA\tmg-cprs\CPRSChart.exe" S=%ASTRO_LOCAL_HOST% P=9260 CCOW=DISABLE SPOOF-VER=%ASTRO_CPRS_SPOOF%
 +
 +
The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:
 +
* %ASTRO_LOCAL_HOST% -> 127.0.0.1
 +
* %ASTRO_CPRS_SPOOF% -> ''1.0.26.66'' (this is the default)
 +
 +
The revised TMG-CPRS shortcut would therefore be:
 +
 +
"C:\Program Files\VistA\tmg-cprs\CPRSChart.exe" S=127.0.0.1 P=9260 CCOW=DISABLE SPOOF-VER=1.0.26.66
 +
 +
==== 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 individual environment variables must be specified if you do not have privileges to specify environment variables. For example:
 +
* %ASTRO_textID% -> ''text9260'' (this is the default value)
 +
* %ASTRO_TEXT_PASS% -> ''not#1sostrong'' (this is the default value)
 +
* %ASTRO_SSH_HOST% -> ''192.168.56.101'' (use the IP address of the installed VistA server)
 +
 +
The revised Text client shortcut would therefore be:
 +
 +
"C:\Program Files\VistA\Putty\putty.exe" -P 22 192.168.56.101 -l text9260 -pw not#1sostrong
 +
 +
==== Change VistA Config shortcut ====
 +
The "VistA Config" shortcut that is used to invoke the VistA user configuration utility uses a command line:
 +
"C:\Program Files\VistA\GUI_Config\GUI_Config.exe" S=%ASTRO_LOCAL_HOST% P=%ASTRO_PORT% CCOW=DISABLE
 +
 +
The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:
 +
* %ASTRO_LOCAL_HOST% -> 127.0.0.1
 +
* %ASTRO_PORT% -> 9260
 +
 +
The revised VistA Config shortcut would therefore be:
 +
 +
"C:\Program Files\VistA\GUI_Config\GUI_Config.exe" S=127.0.0.1 P=9260 CCOW=DISABLE
 +
 +
==== Change CPRS Query Tool shortcut ====
 +
The "CPRS Query Tool" shortcut that is used to invoke the CPRS Query Tool uses a command line:
 +
"C:\Program Files\VistA\CPRS_Query_Tool\CPRSQuery.exe" S=%ASTRO_LOCAL_HOST% P=%ASTRO_PORT% CCOW=DISABLE
 +
 +
The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:
 +
* %ASTRO_LOCAL_HOST% -> 127.0.0.1

Revision as of 15:50, 30 January 2010

  • Download the Astronaut CPRS client onto your Windows machine and install it. During installation, enter the IP address (or hostname URL) and port (9260 by default) of the server you installed in the preceding steps.
  • The SSH tunneling utility PuTTY is installed with the CPRS client. It will start automatically on the first run. Do not close PuTTY; merely minimize it (to the desktop taskbar).
  • Start the CPRS client:
Windows menu -> All Programs -> Astronaut -> TMG-CPRS
  • Use the default login intially:
Access Code: sys.admin
Verify Code: vista!123

You can watch a YouTube video of TMG-CPRS here.

When done with your CPRS session, you can close the PuTTY SSH tunnel. Subsequently, however, you must restart the PuTTY SSH tunnel (and then minimize it) prior to making a new CPRS (or other) connection:

Windows menu -> All Programs -> Astronaut -> Astronaut SSH

You can then restart CPRS again:

Windows menu -> All Programs -> Astronaut -> TMG-CPRS

Changing Astronaut client settings

There are several settings in the Astronaut Client package that can be changed.

Changing environment variables

The Astronaut Client installer sets several Windows environment variables. These are used by the PuTTY SSH client, for example, to establish a secure SSH tunnel to the server. These environment variables must be changed from time to time, in case your network or other installation parameters change.

To access the environment variables, follow these steps.

Windows 7

See this tutorial for step-by-step instructions on editing the environment variables in Windows 7. In short,

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 WorldVistA server which I installed within a Virtualbox virtual machine on my computer. (I also have a standalone WorldVistA server on my network, so I change this variable frequently, depending on the IP address of the WorldVistA server I am using at the time.) Obviously, use the IP address of your own server installation (which is displayed at the conclusion of the Astronaut VistA server installation process).

Securing your installation

Securing the SSH conection

The PuTTY SSH connection is the entry point to your server. You ought to make this connection secure.

  • Change the %ASTRO_SSH_CLIENT_PASS% (either the environment variable or explicitly in the Astronaut SSH shortcuts) to something other than not#1sostrong. This must then also be changed at the VistA server.
  • You can also change the %ASTRO_SSH_clientID% and %ASTRO_PORT% for extra security, but this is an exercise beyond this guide.
Changing the SSH password on the server

(Under construction)

Securing your administrator password

  • You should immediately change the administrator (sys.admin) password (i.e. Verify Code) from the installation default (vista!123), otherwise anyone reading these instructions would know the password of your installation. Duh. You can change this by a variety of methods.
  • Login to the VistA server (in Linux) directly. You will be prompted to change the password the first time. If not, use the command:
sudo passwd sys.admin
  • Login to TMG-CPRS or VistAConfig. The option to change the password at login appears:
  • Change Verify Code: (ticked)
  • In reality, you should change all the passwords of the sample users with which Astronaut VistA comes pre-populated, but since these passwords aren't displayed or published (in general), this is not as high a risk nor as immediate a priority.

Installing in a protected environment

You may wish to install the Astronaut client package on a Windows computer whose access is restricted to certain administrators. The method for doing so is to install Astronaut to the 

C:\Documents and Settings\All Users\Application Data\VistA

folder on your Windows machine. This folder is generally not protected (or restricted to administrators) and can then be accessed by all users.

Environment variables may not be able to be changed on the computer by anyone other than an administrator. When installing without administrator privileges, the startup shortcuts must be changed so that environment variables are not used.

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%

The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:

  •  %ASTRO_SSH_clientID% -> client9260 (this is the default value)
  •  %ASTRO_SSH_CLIENT_PASS% -> not#1sostrong (this is the default value)
  •  %ASTRO_PORT% -> 9260
  •  %ASTRO_SSH_HOST% -> 192.168.56.101 (use the IP address of the installed VistA server)

The revised Astronaut SSH shortcut would therefore be: 

"C:\Program Files\VistA\Putty\putty.exe" -ssh -l client9260 -pw not#1sostrong -L 9260:127.0.0.1:9260 192.168.56.101

Change TMG-CPRS shortcut

The "TMG-CPRS" shortcut that is used to invoke the CPRS client uses a command line: 

"C:\Program Files\VistA\tmg-cprs\CPRSChart.exe" S=%ASTRO_LOCAL_HOST% P=9260 CCOW=DISABLE SPOOF-VER=%ASTRO_CPRS_SPOOF%

The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:

  •  %ASTRO_LOCAL_HOST% -> 127.0.0.1
  •  %ASTRO_CPRS_SPOOF% -> 1.0.26.66 (this is the default)

The revised TMG-CPRS shortcut would therefore be: 

"C:\Program Files\VistA\tmg-cprs\CPRSChart.exe" S=127.0.0.1 P=9260 CCOW=DISABLE SPOOF-VER=1.0.26.66

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 individual environment variables must be specified if you do not have privileges to specify environment variables. For example:

  •  %ASTRO_textID% -> text9260 (this is the default value)
  •  %ASTRO_TEXT_PASS% -> not#1sostrong (this is the default value)
  •  %ASTRO_SSH_HOST% -> 192.168.56.101 (use the IP address of the installed VistA server)

The revised Text client shortcut would therefore be: 

"C:\Program Files\VistA\Putty\putty.exe" -P 22 192.168.56.101 -l text9260 -pw not#1sostrong

Change VistA Config shortcut

The "VistA Config" shortcut that is used to invoke the VistA user configuration utility uses a command line: 

"C:\Program Files\VistA\GUI_Config\GUI_Config.exe" S=%ASTRO_LOCAL_HOST% P=%ASTRO_PORT% CCOW=DISABLE

The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:

  •  %ASTRO_LOCAL_HOST% -> 127.0.0.1
  •  %ASTRO_PORT% -> 9260

The revised VistA Config shortcut would therefore be: 

"C:\Program Files\VistA\GUI_Config\GUI_Config.exe" S=127.0.0.1 P=9260 CCOW=DISABLE

Change CPRS Query Tool shortcut

The "CPRS Query Tool" shortcut that is used to invoke the CPRS Query Tool uses a command line: 

"C:\Program Files\VistA\CPRS_Query_Tool\CPRSQuery.exe" S=%ASTRO_LOCAL_HOST% P=%ASTRO_PORT% CCOW=DISABLE

The individual environment variables must be specified if you do not have privileges to specify environment variables. For example:

  •  %ASTRO_LOCAL_HOST% -> 127.0.0.1
  •  %ASTRO_PORT% -> 9260

The revised CPRS Query Tool shortcut would therefore be: 

 "C:\Program Files\VistA\CPRS_Query_Tool\CPRSQuery.exe" S=127.0.0.1 P=9260 CCOW=DISABLE

Change other client module shortcuts

Don't forget to change the shortcuts for the other modules in a similar fashion:

  • Group Notes
  • GUI Mail
  • Shift Handoff Tool
  • Admin
  • Vitals
  • Vitals Manager
