How to konw quickly which nodes serve as the server or the client about some service?

please first understand the tutorial:ROS/Tutorials/WritingPublisherSubscriber(c++)

Note: The topic name of the publisher and subscriber that you creat must be identical! you can remap the topic name by name Remapping at the Roslaunch and Remapping Arguments at the command-line

I only see tutorials of setting a desired single goal by Pose Goal and Joint Space Goal. I now use ROS Indigo in Ubuntu 14.04.

thanks, this approach is also worth trying,

unexpectedly I launched normally the moveit! setup assistant with the help of gvdhoorn. The total process was as follows:

sudo apt-get install xserver-xorg

sudo dpkg-reconfigure xserver-xorg

sudo reboot

but after rebooting I met the same error .And the touchpad also became invalid . then I tried to check the system Settings, but the settings crashed(could not be opened).

sudo apt-get install ubuntu-desktop

In this way the system Settings could be opened ,then I tried to launch the movit! and succeeded unexpectedly . So I think the "Exit Code -11" is probably related to both the xserver-xorg and the ubuntu-desktop.

rviz can launch correctly. I have not used the tool to do something.

l have not installed 3D drivers and run rviz.

actually I have no explicit destination, and only try to install correctly

thanks for your attention, I follow your steps ,but the error still happens.

REQUIRED process [moveit_setup_assistant-2] has died!
process has died [pid 15519, exit code -11, cmd /opt/ros/indigo/lib/moveit_setup_assistant/moveit_setup_assistant

no SEGFAULT with the apt-get moveit.

oh! I install the moveit! also by the second choice, now I have removed the moveit file and reinstalled the moveit! by the debian packge.but the error still happens

I install the Movelt! by the first choice. Actually I haven't followed the third step ( install the ros-hydro-moveit-full-pr2 )as I don't use it.

I must install correctly the ROS by debian. where can be the problem ?

but I meet a warning when installing dependencies with rosdep install --from-paths src --ignore-src --rosdistro indigo -y

WARNING: Package "ompl" does not follow the version conventions. It should not contain leading zeros (unless the number is 0).

I have followed the instructions to install the MoveIt!. Now I meet an unknown error when launching the MoveIt! Setup Assistant with roslaunch moveit_setup_assistant setup_assistant.launch.
