roslaunch not working
http://wiki.ros.org/rosbag/Tutorials/...
I am following this tutorial to export images from a bag file.
in src
in catkin workspace, I created a new package myimage
. created a folder launch
, and copy-pasted export.launch
in that folder.
I then, did roslaunch export.launch
and I got the error message:
Unable to contact my own server at [http://192.168.1.4:43535/].
This usually means that the network is not configured properly.
A common cause is that the machine cannot ping itself. Please check
for errors by running:
ping 192.168.1.4
For more tips, please see

I have tried this: http://answers.ros.org/question/10238... but, it did not help in my case. It is still showing the same error
It seems you are only trying to run nodes on your computer. Likely, the most reliable setup will be to have ROS_HOSTNAME and ROS_IP unset, and to have ROS_MASTER_URI set to
http://localhost:11311/
Try running
unset ROS_HOSTNAME && unset ROS_IP && export ROS_MASTER_URI=http://localhost:11311/
and then try running your launch file in the same terminal.
