Can you tell what happens when you try and run roscore? Do you get any output?

Give the exact command that you enter and copy the error here.

Try running `roscore -v` to get verbose output from roscore and paste the results in your question. Also can you give the output of running `env|grep ROS` before you run roscore? This is to check your environment variables as roscore may do this if ROS_MASTER_URI is set incorrectly.

Note: strip the `` from the command before pasting it into a terminal. Also what happens when you press CTRL-C in the terminal where the stalled roscore is running?

I gave 'env|grep ROS' o/p: env|grep ROS ROS_ROOT=/opt/ros/fuerte/share/ros ROS_PACKAGE_PATH=/home/abi/t:/home/abi/cv1:/home/abi/wi:/home/abi/colorThresholdProcess:/home/abi/abc:/home/abi/testROSOpenCVFFMPEG:/home/abi/ab:/home/abi/pub_node:/home/abi/tutorialROSOpenCV:/opt/ros/fuerte/share:/opt/ros/fuerte/stacks:/home/abi/ ROSLISP_PACKAGE_DIRECTORY=/opt/ros/fuerte/share/common-lisp/ros ROS_MASTER_URI=http://localhost:11311 ROS_DISTRO=fuerte ROS_ETC_DIR=/opt/ros/fuerte/etc/ros

I'm a bit lost with this one but why don't you try running the Python debugger on these scripts as they are all in Python (at the first debugger prompt, type continue and then when you press CTRL-C you will drop into the debugger): python -m pdb `which roscore`
