Raspberry Pi connection

Running (X)Ubuntu 18.04I wish to use my Wing application (Wing Pro 6.0.12-1) to debug programs on my Pi 3B+.

I have connected by SSH (no login) and can edit programs quite happily. (ssh login ssh pi@192.168.0.37)

I've also established sshfs file sharing.

I'm now trying to set up a debug link.

I've performed each operation up to the 'ssh reverse tunnel.

When I enter : ssh -N -R 50005:localhost:50005 pi@192.168.0.37

the command hangs.

50005 is the port on my PC50050 is the port on the Pi

Not sure what to try next !

With Wing Pro you don't need sshfs or to set up an ssh tunnel manually. The instructions for how to set up to develop on a Raspberry Pi are here: http://wingware.com/doc/howtos/raspberry -- if you've gone through the steps in "Remote Development with Wing Pro" then you should just be able to open a file and debug it, same as if it were running on the local host.

See also http://wingware.com/blog/remote-devel... for some details on remote development.

Thanks - RTFM (Read not browse !).

One reason I thought that it wasn't working was that I am running a set of programs for 'Hats' connected to the GPIO pins on the pi.

Most of these need to be run as 'root' and I was getting failures in the control modules. I'll investigate some more.

ws2812.begin()
File "/usr/local/lib/python3.5/dist-packages/rpi_ws281x/rpi_ws281x.py", line 124, in begin
  raise RuntimeError('ws2811_init failed with code {0} ({1})'.format(resp, str_resp))
builtins.RuntimeError: ws2811_init failed with code -5 (mmap() failed)

Thanks for prompt reply and putting me back on the right path !

You'll either need to set the Host Name in the Remote Host configuration to root@192168.0.37 or instead of starting debug from the IDE start it from the Rasp Pi command line w/ sudo and initiate debug with wingdbstub as described in http://wingware.com/blog/remote-web-dev

Thanks for all your help.

I have now worked out how to set up remote debugging as per http://wingware.com/blog/remote-web-d... can now selectively debug remote python programs running as root.
