RLException: Unable to contact my own server

[plbergeron]

Hi!

We did some test with openptrack on a test rig of 2 imagers and a master and everything was working fine.
Then, we installed everything on the real pcs we are gonna use on our project and now when i try to start the calibration on our master i get this:

RLException: Unable to contact my own server at [http://192.168.100.101:46687/].
This usually means that the network is not configured properly.

A common cause is that the machine cannot ping itself. Please check
for errors by running:

ping 192.168.100.101

but the master's ip is 192.168.100.100:

eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.100.100 netmask 255.255.255.0 broadcast 192.168.100.255

here's the content of my ros_network.env:

ROS_MASTER_URI=http://192.168.100.100:11311/
ROS_IP=192.168.100.100
ROS_PC_NAME=master
ROS_KINECT_NAME=kinect01

and my camera_network.yaml:

enable_people_tracking: true
enable_pose: true
enable_object: true

Camera network parameters

network:

• pc: "node1"
  sensors:
  • type: zed
    id: "node1"
    people_detector: yolo
• pc: "node2"
  sensors:

    people_detector: yolo
• pc: "node6"
  sensors:

    people_detector: yolo

Checkerboard parameters

checkerboard:
rows: 9
cols: 7
cell_width: 0.025
cell_height: 0.025

Maybe i'm missing a file i need to change for ros to see the right address.

Thanks

Can you run export to see whether the ros_network_env is properly updating the ROS_MASTER_URI ? You might need to set it manually if there is an issue with the environment variable?
