This is probably because the source IP of the ping is not 192.168.0.XXX, and you need to belong to the same network in order to ping each other.

Try changing the IP address of the ping source to 192.168.0.XXX.

I already change the IP address of the ping source to 192.168.0.XXX and when to use rosrun urg_node urg_node _ip_address:=192.168.0.XXX it show [Error connecting to Hokuyo: Could not open network Hokuyo: 192.168.0.XXX:10940 could not open ethernet port]

XXX in urg_node _ip_address:=192.168.0.XXX is the part that specifies the IP address of the utm-30lx. if you have not tried urg_node _ip_address:=, try it.

If it still does not work, the IP address of utm-30lx may be wrong.
