In Ubuntu 16.04, I am building a PID controller model in Simulink and am trying to build and deploy it.
After roslaunching in a terminal which starts up all my other nodes (not built using Simulink), I'm trying to connect my Simulink node to my ROS device by using the IP addr outputted from ifconfig but am failing on this step.
It says that
Cannot connect to device. Check that the device address, username, and password are correct.
I have checked my address, username and password multiple times to ensure they are correct. Please see the photos below for details.
I have tried enabling SSH and disabling the firewall, to no avail.

Thank you!

Hi An,
Have you installed openssh-server on your Ubuntu machine? This is needed for the tests to succeed, far as I recall.

hello, is there a way to specify the port on to which ssh should connect? I know thats the issue because i changed the default port and if i personally try to ssh to the machine from the terminal, I successfully connnect. so it is not working on 22. However i could not find an option to specify this. In my case the error is connecting to the ssh server at the ip_address
