I don't have experience with Vicon, but can you get the tracker definition within the built-in VRPN Server?

Maybe the name you are using to connect isn't the correct one, or the server is somehow inaccessible.
I would advise you to give a try with a simple VRPN client application to see if the communication with the server is ok.

Hi everyone,
Sorry if this is a dumb question but could some one explain what I'm doing wrong here?
Setup:
1) A system on the network running Vicon Tracker 1.2 (which I have confirmed is reachable, and from what I understand has a VRPN server built in).
2) I have replaced our tracking configuration file (see changes below) to track the user's head and wand using our Vicon system rather than DTrack.

This just produces "VRPN Warning(n) Tracker0: No response from server for >= t seconds" over and over.
So, does anyone have experience configuring vicon with vrjuggler? If so could you provide a copy of your configuration file? I know with the ViconDataStreamSDK you can just supply the object and address to get an object's position/orientation
ie: object_name@ip_address, but I'm not sure how that works with vrpn.
Thank you for any help you can provide!
