Problem configuration with roscore?
Hi, I recently install Ros Kinetic, using the tutorials, but I've seen some troubles while I launch the roscore, because it only launch when I have internet connection.
:~$ roscore
... logging to /home/luigi/.ros/log/8a34264e-89af-11e7-b0b2-3bf20ac5beb2/roslaunch-ubuntu-4007.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.
Unable to contact my own server at [http://ubuntu:36413/].
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 ubuntu
For more tips, please see

The traceback for the exception was written to the log file
**But ,when I get internet conection, there's no problem

What is the output from
printenv | grep ROS? Also, what do you mean by internet connection? Do you mean WiFi or a wired connection?I edited your question to make it more readable. Using the Preformat Text (
101010) button on terminal output and source code makes questions much easier to read and answer.:~$ printenv | grep ROS ROS_ROOT=/opt/ros/kinetic/share/ros ROS_PACKAGE_PATH=/home/luigi/RoboticsCourses/catkin_ws/src:/opt/ros/kinetic/share ROS_MASTER_URI=http://localhost:11311 ROSLISP_PACKAGE_DIRECTORIES=/home/luigi/RoboticsCourses/catkin_ws/devel/share/common-lisp ROS_DISTRO=kinetic
thanks, I mean wifi connection.
