Hey,
We're working on our robot running Ubuntu 14.04 and ROS indigo. Currently, we are trying to connect a Sick TIM 571 laserscanner via ethernet and the Ubuntu 14.04 tries to connect to the Ethernet but it keeps on failing and never connects to it. It works perfectly in Windows using the SOPAS Engineering Tool. Also I installed ROS drivers http://wiki.ros.org/sick_tim and when I run the following command : roslaunch sick_tim sick_tim571_2050101.launch, I keep on getting the following error :
[FATAL] [1459886892.692926805]: Could not resolve host: ... (1)(Host not found (authoritative))
[FATAL] [1459886892.693107727]: Failed to init device: 1
[ERROR] [1459886892.693164271]: sendSOPASCommand: socket not open
SOPAS - Error stopping streaming scan data!
sick_tim driver exiting.
I have also tried (from http://answers.ros.org/question/207220/connecting-a-sick-laserscanner-via-ethernet/):
"On edit connections, click add, go to ethernet tab, set device MAC address to the right ethernet port, got to IPv4 Settings tab, set method to Manual and enter these settings: Address: 192.168.0.1 Netmask: 255.255.255.0 Leave Gateway open and click save." but this also does not help in setting up the ethernet connection between SICK TIM 571 and Ubuntu 14.04.
I am not able to PING the sensor or anything because it is not even getting connected to the Ubuntu 14.04.
Does anyone know how can I set up the ethernet connection between SICK TIM 571 and Ubuntu 14.04?
Thanks in advance.

Did you edit the sick_tim571_2050101.launch to enable TCP connection? Have you accidently changed the Tim's default IP address? Are you connecting the Tim directly to your Ubuntu or is a router/DHCP/switch between them?

If you haven't changed the default IP address and you connect the TIM directly to your Ubuntu, you need to set a static IP address in Ubuntu to 192.168.0.2, because 192.168.0.1 conflicts with the default Tim IP address

Yeah.. I did edit the sick_tim571_2050101.launch.. and I am connecting TIM directly to the Ubuntu. Yeah.. I think it is some IP conflict issue. How can I set a static IP address in Ubuntu to 192.168.0.2? Thanks in advance.

Take only Step 1 from this HowTo and then restart your system. You don't need to add the gateway line.
