VenueVNCServer
The server component of the VenueVNC shared application is now available for download:

http://www.mcs.anl.gov/fl/research/accessgrid/software/releases/2.3/patches/VenueVNCServer.py

This program is all Python code, so works similarly on the three supported platforms:  Windows, Linux, and OSX.  Platform variations are given here:

Windows
- Depends on RealVNC (http://realvnc.com/)
- Looks for server executable in the RealVNC install directory
   (C:\Program Files\RealVNC\VNC4\WinVNC4.exe)
- Only the primary display can be shared
- Uses port 5900 for server

Linux
- Depends on tightvnc (http://www.tightvnc.com) (other vnc packages may also work)
- Looks for server executable in /usr/bin/Xvnc
- Any virtual display can be shared via the '--display' option
- Uses port 5900+displaynumber for server (e.g. 5909 for display number 9)

OSX
- Depends on OSXvnc (http://www.redstonesoftware.com/osxvnc/OSXvnc.html)
- Looks for server executable in /Applications/OSXvnc.app/OSXvnc-server
- Only the primary display can be shared
- Uses port 5900 for server

Security Notice
Users should note the following with respect to security and VNC:
- VNC is regarded as a security risk
  (refer to http://www.realvnc.com/faq.html#security)
- Firewall holes must be opened to allow access to the VNC server from
  outside your network.  Ports are identified above in the plaform notes.

Execution

VenueVNCServer.py will typically be executed as follows:

   python VenueVNCServer.py --venueUrl https://someserver:8000/Venues/default

On OSX, the environment settings file must be sourced into your environment
before running VenueVNCServer.py (the file is /Applications/AccessGridToolkit.app/Contents/Resources/setupenv.sh).

A complete list of command-line options is available by passing the '-h' option.

Bugs should be filed in the AccessGrid bugzilla database at http://bugzilla.mcs.anl.gov/accessgrid .
