Intel Realsense nodelets running with remote roscore are dying (bond broken)

edit

Hi, I am having a hard time finding a solution to my issue. Here is my setup.

• Computer 1 (master computer): roscore, a subscriber that subscribes to a custom msg.
• Computer 2: "roslaunch realsense2_camera rs_camera.launch", a subscriber that subscribes to a depth topic and publishes our custom msg.

Both computers are running Ubuntu 16.04 with kernel 4.15.0-107-generic.

Both computers are using Kinetic as their ROS version.

And both computers are using realsense SDK version: 2.36.0.

I have set the ROS_MASTER_URI on computer 2 to http://computer1IP:11311, both computers are connected via Ethernet. (following this tutorial)

When I run "roslaunch realsense2_camera rs_camera.launch" on computer 2 this is the error I get:

[ INFO] [1594757854.382965902]: RealSense Node Is Up!
[camera/realsense2_camera-2] process has finished cleanly
log file: /home/<user_name>/.ros/log/e172c1b8-c651-11ea-8aea-00073273924f/camera-realsense2_camera-2*.log

I have tried following the solution here but it does not work for me. It would help out a ton if someone knew how to fix this issue.

Here is the output of env | grep ROS: (If it's helpful)

ROS_ROOT=/opt/ros/kinetic/share/ros    
ROS_PACKAGE_PATH=/home/user_name/catkin_ws/src:/opt/ros/kinetic/share    
ROS_MASTER_URI=http://computer1IP:11311    
ROS_PYTHON_VERSION=2    
ROS_VERSION=1    
ROSLISP_PACKAGE_DIRECTORIES=/home/user_name/catkin_ws/devel/share/common-lisp    
ROS_DISTRO=kinetic    
ROS_IP=localhost
ROS_ETC_DIR=/opt/ros/kinetic/etc/ros

EDIT I found a fix that works so far, I don't know if it's a permanent solution but so far it works.

In my .bashrc on computer 2 I used to have this:

export ROS_MASTER_URI=http://computer1IP:11311
export ROS_IP=localhost

I changed it to:

export ROS_MASTER_URI=http://computer1IP:11311
export ROS_MASTER_URI=computer2IP

I'm not fully sure why using computer2IP instead of localhost fixes it, but my roslaunch no longer gives me the error I was having earlier.

I hope this helps someone and if anyone has a more correct way of doing this please let me know.
