Restoring connect opensnitch-ui #225

Closed denji closed 5 years ago

We need a procedure to restoring connect opensnitch-ui after the fall of the demon opensnitchd and restarting opensnitchd.service.

At least on Debian, systemd restores the daemon if it exits with error (after 30s). And the ui is updated as expected:

If the connection to the UI is not restored maybe it's a different problem. journalctl/daemon logs would be helpful
