Hi All,

I am trying to run ROS across 2 machines, master is starting with out any issues when I tried to run listener getting below errors.

**root@test:/opt/ros/indigo# rosrun rospy\_tutorials listener.py**  
**[rospack] Error: package ‘rospy\_tutorials’ not found**  
**find: ‘’: No such file or directory**

I have followed below procedures.

System 1-  
setting static IP-  
ifconfig eth0 192.168.0.1 netmask 255.255.255.0  
route add default gw 192.168.0.1 dev eth0

export ROS\_IP=192.168.0.1  
export ROS\_HOSTNAME=192.168.0.1

roscore &

export ROS\_MASTER\_URI=[http://192.168.0.1:11311/](http://192.168.0.1:11311/)  
rosrun rospy\_tutorials listener.py

System-2

setting static IP-  
ifconfig eth0 192.168.0.2 netmask 255.255.255.0  
route add default gw 192.168.0.2 dev eth0

export ROS\_IP=192.168.0.2  
export ROS\_HOSTNAME=192.168.0.2

export ROS\_MASTER\_URI=[http://192.168.0.1:11311/](http://192.168.0.1:11311/)
