when Running ROS across multiple machines ,it can share master for two machines,but when run a node ,it appear something like Couldn't find an AF_INET address for [hostname],I don't know why. when I run a node in machine a,it pub a topic named "message",but I can't sub the "message" for a node from machine b,but when I use "rostopic list ",it has the topic named "message"
Searching for your error message finds a few other users who have had the same problem and resolved it. Have you tried any of their solutions:
I had same problem while ı am trying the upper link. I resolved, resolve is here.
open the .bashrc files and add this code.
You'll see those things like that:
export ROS_MASTER_URI=http://localhost (or something like that which is not your ip):11311
export ROS_HOSTNAME=(your machine name)
and you must change it like that:
export ROS_MASTER_URI=http://30.10.21.46:11311
export ROS_HOSTNAME=30.10.21.46
change your ip adress.
