VRPN Error

[tonyrosuoitace]

I have been successfully using the VRPN streaming from the tracking tools for some time now. All of a sudden I get VRPN Error: No response from the server. Both machines have connectivity between each other. I have the right IP and trackable name but I cannot figure our why it does not work. The VPRN client is a ROS node on an Ubuntu machine. Any ideas?

Are you using Multicast or Unicast?

I am using VRPN.

Which version of Tracking Tools are you using and what version of VRPN is the ROS node compatible with?

[tonyrosuoitace]

I am using Tracking Tools version 2.5.0 x64 with VRPN 7.20. ROS node is using VRPN 7.28. The version difference wasn't an issue before as it was working. Now, the server does not respond. We can ping both ways, but the ROS node sees no data from the VRPN server but has connectivity.

We are at a complete loss at what is going on.
