VNC: how to set up your Raspberry Pi for virtual network computing

Seeing as the connection between monitor, mouse, and keyboard to the Raspberry Pi is rarely practical, the minicomputer is often operated in headless mode (via SSH) via the command line. Thanks to virtual network computing (VNC), however, there is an alternative solution that also allows remote access to the user interface. To use this technology based on the RFB protocol, you only need to set up...

Flush DNS: how to clear your DNS cache

Various operating systems, such as Windows or macOS, automatically save information about address resolution from systems and applications in the network in a DNS cache. For Linux there are also corresponding services, though they have to be installed by the user.

What is the hosts file and how do you edit it?

The hosts file used to resolve website names so that certain IP addresses could be accessed. The method was largely replaced by the DNS (domain name system). However, the hosts file is still indispensable for local networks. In addition, certain rules can be set for websites e.g. to block them. We show you where you can find and edit the hosts file in your operating system.

Raspberry Pi: activating and using SSH access

Raspberry Pi has established itself as a reliable basis for servers of various types. Access – for configuration and maintenance purposes – rarely takes place on the mini computer itself, but mostly on a desktop computer in the same network. The communication protocol is the secure SSH (secure shell), which isn’t enabled by default and hasn’t been for some time. How to activate the Raspberry Pi...
