We have had a bricked Vigor130, which would not reset. We were unable to reach it even after resetting multiple times.

It was pingable on 192.168.1.1, but did not reply to any open ports with nmap scans, nor did it act as a dhcp server.

We connected a TTL adapter to the 4 pins on the board to see if there's a serial console on it.

Pinout:

+3.3v | RX | TX | GND |

This nginx configuration allows to restrict access via different methods to separate users.

This is very useful for private docker registries, where you want every member of your team to be able to fetch Docker images, but only some users (admins and CI users) to push new images to the registry.

Example:

• User write can use GET, POST, PUT, DELETE and everything else.
• User read can only use GET and HEAD.
• Anonymous users are denied access entirely.
