I took the IP from SOPAS software in windows. I guess that automatic address created by windows. Should I edit IP address for laser scanner manually (to 192.168.1.2?) in SOPAS before connect it to ROS? Otherwise Linux can't find the IP address of laser scanner automatically. > That "automatic address" looks suspiciously like what you get when a > computer is configured to use DHCP but there is no DHCP server available, so > it defaults to something like that.
