during the tutorial I tried the following but it showed the corresponding error as follows: "$ rosrun turtlesim turtlesim_node" "[ERROR] [1347908650.466741617]: [registerPublisher] Failed to contact master at" "[localhost:11311]. Retrying.."

Can anyone tell me how to fix this?!

(When trying to reset my network as said in ros/networksetup as follows, it keeps being messed up the same way: "$ export ROS_HOSTNAME=localhost $ export ROS_MASTER_URI=http://localhost:11311" Maybe I didn't do this correctly, how do I know for sure what to put in "localhost" and "http://localhost:11311"?)
