[ros-users] actionlib tutorials using remote master

I followed the actionlib tutorial given
created fibonacci_server.py and fibonacci_client.py which I have attached.
If I run roscore on the same computer as I'm running the server and client,
the whole connection (server-client) works and I am able to echo the
feedback, status, result etc. However, when I run roscore on a remote
machine i.e. a remote ROS master by setting my ROS_MASTER_URI, the process
does not work. I even made sure that they have the same time by running
ntpdate on both machines.

Both computers are running Ubuntu 12.04 with ROS Groovy. Is there something
more I need to do in order to make the action server work with a remote ROS
master? Please let me know if you need more information and thanks for your
