The more you become involved with all this IT/software/programming stuff, the faster you will discover that the possibilities of related automation make you dreadfully lazy.
One of those moments in which one thinks of a possibility for automation or simplification is, if one logs in for the 48th time via puTTy in his RaspberryPi (or Linux system).
Because especially with so often repetitive processes you can save a lot of time, if you take the trouble to abbreviate this process in the future.
How you can spare yourself the input of username and password for your RaspberryPi in the future is explained in the following article.
Hints for our lovely english readers: Basically, many of the articles on Nerdiy.de are translations from the original german articles. Therefore, it may happen here and there that some illustrations are not available in english and that some translations are weird/strange/full of mistakes or generally totaly wrong. So if you find some obvious (or also not obvious) mistakes don't hesitate to leave us a hint about that in the comment section.
Also please don't get confused, that instead of a "dot" often a "comma" is used as decimal separator. 🙂
I know the following hints are always a bit annoying and seem unnecessary. But unfortunately, many people who knew it "better" from carelessness lost their eyes, fingers or other things or hurt themselves. In comparison, a loss of data is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Even the coolest project is worth no injury or other annoyance. https://www.nerdiy.de/sicherheitshinweise/
Before you start with this article, you should have prepared the RaspberryPi so far that it can be reached via the network and controlled by SSH.
RaspberryPi – Setting up for Nerdiys!
RaspberryPi – The first configuration
RaspberryPi – Controlling the RaspberryPi via SSH
In the following list you will find all the parts you need to implement this article.
Log in via SSH on the RaspberryPi
To get started, you first need to log in to RasPi with SSH on Putty. How to do it is described in the article RaspberryPi - Controlling the RaspberryPi via SSH.
Create an SSH key pair
In order for the login to work in a remote system without password entry, you must exchange the keys that encrypt your connection to the system in advance and thus make known to both systems.
To generate these just enter the following command.
ssh-keygen -t rsa -b 4096
Exchange of the public key
ssh-copy-id -i id_rsa.pub pi@rasPi
CAUTION: Keep in mind that you are opening a potential security hole on one of your systems. Use strong passwords – at least on the system you log in to the remote system – and handle them responsibly.
I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂
P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you appreciate it that I share these information with you, I would be happy about a small donation to the coffee box. 🙂
