port > 1024

Post by todd »

Hi,
Currently the the Rigid Body Tool streams out the data on port 1001. For those of us trying to receive the data on a Unix like OS this presents a problem as only processes running as root can bind to ports under 1024. Is it possible to configure RBT to stream on a different port?

Which streaming transport are you using, NatNet, TrackD or VRPN?

If you are using NatNet, it should be available on port 1510.

NatNet Network Details : port 1510, multigast group 1001, UDP multicast

Hi Birch,
I am referring to NatNet which appears to be using multicast group 224.0.0.1 and port 1001. I don't see anything on port 1501. We got this numbers from a post somewhere on these forums, I believe.

I am not sure what you mean by multicast group 1001 since multicast groups all must have addresses in range 224.0.0.0 to 239.255.255.255.

Thanks.

multicast group is 224.0.0.1

port 1001 is the multicast group port for data packets sent from server to client.

port 1510 is the port for exchanging request/response packets between the client and the server, typically for commands, not data.

I'm afraid currently it's not possible to change the port the RB Tool is streaming from. We'll look into getting this changed for the next release.

An alternative for now would be to use either VRPN or TrackD. I believe both have Unix client libs/source available?

Morgan,
thanks for the response. It would be great for a next release to do something in regard to this as it causes. the VRPN and TrackD aren't really what we are looking for.
