I’m not a big fan of the free-ish routers you get from your internet provider in Switzerland. Most devices are just cheap “crap devices” and they lack of any slightly advanced feature. Therefore I’m always going with a Ubiquiti Edge Router!
Adding and removing nginx response headers
If you’re using nginx as your preferred web server, reverse proxy, load balancer or HTTP cache, then you might be familiar with HTTP response headers. Nginx allows you to customise those HTTP response headers very easily.

Some parameters can be used for performance tuning, others can be critical for security hardening. What is sysctl? sysctl is an interface to view and dynamically change parameters in Linux and other *NIX operating systems. In Linux, most of the dynamic Kernel settings can be […]
TCP connection states

So I started to look out for some better alternatives. If you’re looking for something more “enterprisy”, you’ll definitely land on […]
Using PPPoE on Linux
When it comes to internet connectivity in Switzerland, you might stumble across ADSL or VDSL. Most of the time you’ll end up with a router provided by the provider, which is already pre-configured with the connection information. This setup might work for the majority of users, but if you’re a pro-user or enterprise with special needs, […]
