TCP timing out, help? #152

Closed Alexandre-Caldeira closed 2 years ago

Alexandre-Caldeira commented 2 years ago

Using the Troubleshooting Guide, I tried to start a TCP connection with a SICK LMS111, having already set a static IP (in SOPAS Tool in Windows), when I do:

nc -z -v -w5 169.254.0.2 2112

I get:

nc: connect to 169.254.0.2 port 2112 (tcp) timed out: Operation now in progress

I have honestly no idea what is wrong, I have tried multiple ROS packages, distros, even changed Linux distros but nothing seems to point to the issue nor solve it.

Any suggestions? Any other troubleshooting tips?

PS.: I have tried to set the ip to something like 198.168.XX.XXX but SOPAS won't allow it, unless it's something like 169.254.XX.XXX (but I don't think that's related to nor the actual issue here).

I guess, that you are using DHCP. We strongly recommend to use a static IP setup. For this you have to switch from DHCP to static. Please ask you sys admin for details. Also check for 192.168.xxx.xxx instead of 198.168.xxx.xxx. Also it is a good idea for a local connection between your PC and the lidar to use a separate ethernet interface (e.g. USB/Ethernet-adapter). There you can establish your own subnet.
