VRPN info
I'm having some trouble getting VRPN working. I'm trying to use the basic vrpn_print_messages client from the standard VRPN package for linux, and I can't seem to get a connection to work at all. At first, no UDP packets were making it through, but I realized the PPT machine had a firewall on - once I disabled it, I was able to communicate with the PPT computer, but there was no VRPN server active on the regular port (3883). Which port does PPT's VRPN server run on? Also, once I can get a VRPN connection established, what's the tracker's name - e.g. Tracker0, PPT0, or something else? If you've gotten VRPN to work successfully, please let me know. Thanks, I appreciate it very much!

You connect to the VRPN server generated by PPT as:
PPT0@yourmachine Capitalization matters, so be sure the three letters PPT are upper-case. The fourth is the number zero. I'll have to check on the port number and see if it's something other than 3883. |

We use what we understand to be the VRPN default port of 39684. If you're still having trouble please let us know.

A few pieces of info - the VRPN code I'm using reports version 6.06, while the PPT VRPN server reports 6.04. Also, this is PPT version 2.02. I've made sure VRPN is selected in the configuration dialog, and that the streaming mode has been entered when I've tested. Here's the output of one of the test clients included with the VRPN linux code: Code:
sdiverdi@reality [7:05pm] ~/research/fogscreen/ppt/vrpn/client_src/pc_linux 94 > ./vrpn_print_messages 192.168.1.100:39684 vrpn_Log::open_log: Log file "vrpn_temp.deleteme" already exists. Writing to /tmp/vrpn_emergency_log instead. vrpn_Connection: VRPN Note: minor version number doesn't match: (prefer 'vrpn: v er. 06.06', got 'vrpn: ver. 06.04 0'). This is not normally a problem.

Anything I can check / try out? Thanks again! |
