The following CD keys are official and original from Microsoft, mainly used for Windows XP Professional Service Pack 2/3 VOL/VLK system images, which are the easiest ones to find on the Internet.

Nginx TLS SNI routing, based on subdomain pattern

Nginx can be configured to route to a backend, based on the server's domain name, which is included in the SSL/TLS handshake (Server Name Indication, SNI).
This works for http upstream servers, but also for other protocols, that can be secured with TLS.

prerequisites

• at least nginx 1.15.9 to use variables in ssl_certificate and ssl_certificate_key.
• check nginx -V for the following:

  ...

Setting up a Docker container as a DHCP server

In this guide I’ve tested a number of different commands and configurations using Docker to run a container with dhcpd (+macvlan driver) to serve my clients in my home network. In the end i’ll migrate from my Windows 2012 R2 Server running DHCP to a much more lightweight Docker container (7.42 MB in total). Wow.

My home environment:

• Firewall (Juniper)
  • I’m running IP helper for bootp which in this case means that i relay DHCP requests from various VLANs into one where i've placed my Windows 2012 R2 server. This is also where my container will live. See the FW configuration below:

version: '3.3'

services:
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    restart: always
    networks:
      - myvlan
