How to configure my node/computer for processing

edit

Thank you greatly for your insight on the machine tag. My configuration is as follows: Hostname: 10.0.0.166 [PC] Hostname: 192.168.1.235 [Robot]

ROS_MASTER_URI is on the robot.

Inside the launch file I wrote it as:

<machine name="DellLaptop" address="10.0.0.166" env-loader="/opt/ros/melodic/env.sh" user="Cae"/>

Yet when I run the roslaunch from the remote pc I get the following:

network error connecting to [10.0.0.166:22]: timed out

Furthermore, when I try to ping from the robot, to 10.0.0.166 (PC) I get a message that I lost all the packages... it's not sending anything. Would you know?

I assume you've already looked through the network setup tutorial and that you can ping the robot from your PC since you're able to connect with PuTTY, but you could check anyway. My guess is that there's a NAT issue, so that 10.0.0.166 isn't the PC's address as seen by the robot. There are tools, like wireshark, you can use to see the IP address of incoming connections, but there may be an easier way if you do some searching; this SO post suggests the pinky command, but I have no experience with it.

Are you connected to the same network? Maybe the ip of your pc is about another network or if you have ethernet and wifi you are using the wrong device ip
