This device is labeled as a presentation player, but it is really a VNC viewer in a box! As most of the Linksys devices around today, it runs a customised version of Linux, just waiting to be hacked…
As the software shipped with the WPG54G is Windows only, some workarounds are needed to get it to play nicely with Linux or Mac. Here’s the details:
Firstly, you’ll need some form of VNC server set up on your PC. For GNOME users, GNOME 2.8+ ships with the Vino remote desktop utility. Windows users can use just plain old RealVNC, and I’m sure there is a solution for OSX users too, but I haven’t ever used a VNC server on a Mac before.
NOTE: for this to work correctly, your VNC server must be set to not require a password. This might not be necessary, but I believe the password sent to the WPG54G is encrypted. Without knowing the encryption, it won’t work.
The Windows utility does some sort of local subnet broadcast to discover the WPG54G, but for us, we will connect directly to the WPG54G’s IP address. For the WPG54G to initiate a connection to your VNC server, the windows software uses a GET URL for the unit to discover the client.
To start it, I used curl in Linux, but you could use any web brower. Fire up the URL
http://IP address/connect.html?DTYPE=plain&ov_name=your name&ov_passwd=whatever you want
and the WPG54G should start a VNC connection to your client’s IP address
