Preface The Raspberry Pi official has provided an image list: Http://www.raspbian.org/RaspbianMirrors, but because of the server in foreign countries, we install and update the software is always not satisfactory speed, and sometimes a time-out connection caused the installation failure.So there are some mirror stations, such as Ali Open source image, NetEase op

Securi-Pi: Uses Raspberry Pi as a stepping stone for securityGuideLike many readers of LinuxJournal, I have also lived a very common "technology nomadic" life today, from one access point to another between networks, we are in different places in the real world, but we are always connected to the Internet and other networks that are commonly used.

GuideLike many linuxjournal readers, I have also lived in today's very popular "tech nomads" life, between networks, from one access point to another, where we are in different parts of the real world and remain connected to the Internet and other networks we use on a daily basis. Recently I have found that more and more network environments are starting to block common ports such as SMTP (port), SSH (Port 22), and so on. When you walk into a café and want to SSH into one of your servers to do s

Second, make full use of each piece of hardware to provide "soft" services, in terms of soft services, you can use Raspberry Pi

sprinkler and an electric rice cooker. Therefore, the Raspberry Pi Plus relay can fully extend its control over external devices. Dry-reed Relay refers to the reed relays, which are compared with the general relays, and their switching speed and life are greatly improved. The use of the relay is very simple, only the level control of its pin to complete the cont
