Some users may wish to run WINGSPAN at the GROSSC via a remote login. There are two steps to remember in order to create a remote X-windows session using IDL. The first is that you must change the authorized remote users for the local server. For example, with DecWindows, you choose the Security command from the Session or Terminal Manager's menu, type the ``node::username'' for your remote account and click on Add. Save the change by choosing the Save Current Setting command. Unix users will want to use ``%xhost +remote_host_name'' to accomplish the same thing. Logon to the remote host via ``SET HOST'' (``rlogin'' or ``telnet'' for Unix) and execute the DCL command: ``SET DISPLAY/CREATE/NODE=local_host_name'' (add ``/TRANSPORT=TCPIP'' if logging on from a Unix system).
