+The IDL section contains downloads for windows (''.exe''), linux (''.tar'') and Mac (''.pkg'').
-===== Windows installation =====
+===== Network license setup =====
+IDL needs to communicate with our license server in order to run. The license server is directly accessible from the campus network, but you need to take special steps to connect from off-campus.
+After downloading and running the installer, newer versions of IDL start a "license wizard".
+  * Our MyPhys downloads page includes a minimal ''license.dat'' file, which you should download.
+  * After selecting the option for a network license, provide this file to the license wizard.
+We emphasize that this doesn't provide a local, standalone license - we only support use with the network license server. If you need to run in disconnected mode, you will need to purchase your own license directly from IDL (Exelis).

-==== Alternative method for network license setup ====
+===== Running IDL from off-campus =====
-After installing newer versions of IDL, a "license wizard" runs. If you select the option for a network license, our downloads page has a minimal ''license.dat'' file, which you can download and provide for IDL. Note that this doesn't provide a local license; you still need to be able to connect to the license server to use the program.
+To access the license server from outside, the easiest, and recommended method is to connect to the [[http://it.umn.edu/virtual-private-network-vpn|University VPN]].
-===== Running IDL from outside Tate Lab =====
+Alternatively, you can set up a network "tunnel" using ssh.
-The IDL license server is only directly accessible within Tate Lab. To access it from outside, the easiest method is to set up a network "tunnel" using ssh.
+==== Windows ssh tunnel directions ====
-**To use IDL from outside Tate Lab on Windows**
+This is one of many possible methods (actually it's probably easier to use **MobaXterm** than putty - we'll aspire to replacing these one day)
+  * Download the free Windows ssh client Putty. Putty doesn't need installation, just put putty.exe in any convenient directory such as ''C:\\Program files\putty.exe'', or even on the desktop.
-  * Download the free Windows ssh client Putty. Putty doesn't need installation, just put putty.exe in any directory, e.g. c:\program files\putty
+  * As above you need to define an environment variable to tell IDL the location of our license server, but this time we will be tunneling the connection through localhost:
-  * Click the Windows Start button, right-click "My computer", and choose "Properties" to open the system properties dialog. Go to the "Advanced" tab and click on the "Environment Variables" button. Beneath the field labelled "System variables", click "New". In the Variable Name field, enter LM_LICENSE_FILE, in the Variable Value field, enter 1700@localhost, then hit the ok button.
+    * Open the System control panel.
-  * Click start, go to "run" and type <code>
+    * Click the Advanced tab, and click the Environment Variables button. Click the New button below the System Variables box and enter the following information:
-"c:\program files\putty\putty.exe" -ssh physics.umn.edu -P 22 -l <your_Physics_username> -N -L 1700:idl.spa.umn.edu:1700 -L 31700:idl.spa.umn.edu:31700</code>
+      * In the Variable Name field, type LM_LICENSE_FILE in uppercase letters.
-and enter your password once asked. Nothing will happen afterwards (minimize the putty window).
+      * In the Variable Value field, enter 1700@localhost
-  * Start IDL (note that the previous step has to be done every time before you start IDL).
+    * If LM_LICENSE_FILE has already been defined for another software product, the definition of this license file can be appended using a semi-colon (;) as the delimiter. For example: %%C:\License\mylicense.dat;1700@localhost%%
-  * You can create a batch file that merges the above steps. Create a file called startidl.bat in the directory where idlde.exe is located (usually C:\Program Files\RSI\IDL63\bin\bin.x86). Open the batch file with a text editor and type
+    * Save the settings.

+    * Click start, go to "run" and type <code>"c:\program files\putty\putty.exe" -ssh ssh.physics.umn.edu -l <your_Physics_username> -N -L 1700:idl.spa.umn.edu:1700 -L 31700:idl.spa.umn.edu:31700</code> and enter your password once asked. Nothing will happen afterwards (minimize the putty window).

-**On Mac OS X**
-You can run a similar command to the above in Terminal, to create the same ssh tunnel to the license server:
+==== Mac OS ssh tunnel ====
-  ''ssh physics.umn.edu -P 22 -l <your_Physics_username> -N -L 1700:idl.spa.umn.edu:1700''
+  * Follow the section about LM_LICENSE_FILE under the OS X installation instructions above, replacing the LM_LICENSE_FILE line with ''setenv LM_LICENSE_FILE 1700@localhost'' or ''export LM_LICENSE_FILE=1700@localhost'', depending on your shell. Note: This step only needs to be done once.
+  * Launch the Terminal application and run the following command to create the ssh tunnel to the license server:<code>ssh ssh.physics.umn.edu -l <your_Physics_username> -N -L 1700:idl.spa.umn.edu:1700 -L 31700:idl.spa.umn.edu:31700</code> Note: This step needs to be repeated each time you want to run IDL.
