After setting up a DHCP server on a Raspberry Pi running Linux I get working leases for my clients. However, these are not static. It can happen that my smartphone gets a new IP address the next it connects: 192.168.0.161 instead of 192.168.0.160. For some clients I want to make Read more…

DHCP Server on Linux with Raspberry Pi

My internet provider is Unitymedia. Their default router comes with a DHCP server. Honestly, it’s one of the worst products I ever had to work with. My private network is 192.168.0.x.

A 5xx error code is returned by a web server when something went wrong: The server was not able to process the request. For a reverse proxy, a common 5xx error message is 503, meaning that the backend server is not reachable. In the technical architecture of my blog site, the Read more…

A look back at 2016

2016 is history. As I have done in last year, I will use the start of a new year to look back at my private blog to see if my experiment is still on track. 2016 was the first year my blog was up and running for a full year. Read more…

Operate GateOne behind Apache reverse proxy

After installing GateOne on my Raspberry Pi 2 Debian system, I can log on to SSH via HTTP and browser. But only from my internal network, as the external accessible port is blocked by Apache. To add GateOne from outside, I either can disable Apache (no, won`t do it) or Read more…
