I got it working now. The reason was that i'm using ssh to access other machine and i was setting ROS_MASTER_URI for only one.

You have to set the environment variables for each terminal window if master is not on the same machine. And yeah, setting only ROS_MASTER_URI will do the trick.

Thanks for your help, much appreciated.
