I have 2 computers connected by VPN.
First computer have ip-address 10.1.100.1 run server xml profild
Second computer have ip-address 10.1.100.2 run clinet by use node demo_node_cpp listen and talker
listen and talker can communication together but I can't see topic by
ROS2 command
ros2 topic list
ros2 topic echo /chatter
ros2 bag record -a
ROS2 code
import rclpy
from rclpy.node import Node
rclpy.init()
node = Node("topic_list")
node.get_topic_names_and_types()
Main my problems are can't see topic available and can't use ros2 bag record -a.
How can i solve problem on it by constrain I want to use discovery server because it can use by set only server ip-address.
I followed the following tutorial: https://index.ros.org/doc/ros2/Tutori... and I'm seeing the same problem...
I ever try that tutorial too. That tutorial tell rqt_graph can verify node and structure but I can't use them to verify. I see some node not all structure...
I have reported this as an issue on the rmw_fastrtps github project: https://github.com/ros2/rmw_fastrtps/....
