Ping operation not working in Switching & Routing lab question

The ping operation isn’t working in [email protected] before adding routing entries. Ping doesn’t work between any of the boxes after completing the steps under “hint” either.

When attempting to ping from [email protected]_host, or from within any of the boxes running the various “app##”, you just get the error

ping: socket: Operation not permitted.

This is the message you get trying to ping at any point in the lab exercise. Something seems broken.

EDIT TO ADD: Can’t use Ping operation in the next lab section either (DNS). Gives the same socket error.

I am facing the exact same issue.
