Can you give some more details on your setup? Where is the master? Which specific wiki page did you follow? Did you set both ROS_HOSTNAME and ROS_MASTER_URI? Is the name resolution working on both machines? And can you run Rviz when you just use one machine?

i followed this page: http://wiki.ros.org/ROS/NetworkSetup

the master of my config is the Raspberry , in the bash file i add : export ROS_MASTER_URI=http://raspberry IP:11311 eport ROS_HOSTNAME=raspberry IP export ROS_IP=raspberry IP.

the remote PC bash file: export ROS_MASTER_URI=http://raspberry IP:11311 eport ROS_HOSTNAME=remote pc IP export ROS_IP=remote pc IP

when i run Rviz in one machine it works succefully. but when i connect whith ssh to the raspberry, and i run roscore, then roslaunch rplidar_ros view_rplidar.launch, it doesn't work (no Rviz response).

what the you mean whit the same resolution working on both machines?
