I tried to start the sick_tim package, but it can't connect to the TiM Laserscanner. With Windows and SOPAS ET I can config the scanner. The IP is set to and the Subnetmask to With Ubuntu 12.04 and ROS Hydro I can ping the scanner but with ROS I can't connect.

Here the console output:

Just to be clear: You set the scanner IP to, right? What did you set your computer's IP to? If you also used, you weren't pinging the scanner, you were pinging yourself. Try something else in the 169.254.8.* range, like . Also see sick_tim #34.
