Setting Up PuttyДЇirst of all the current SSH session should be terminated and Putty should be started again. However, both the directory and the file name can be chosen freely. I named the key revpi_connect_ to keep the overview when using several RevPis. puttygen considers a private key without passphrase to be questionable and therefore asks again if you really want to save the key without passphrase, which I of course answered with Yes. ssh analogous to the RevPi and saved the key there by Save private key. After all, I donвЂ™t want to have to deal with that annoying password.

For experimental operation, a password is usually not necessary. From a security point of view this is definitely recommended. The private key can be secured with a passphrase. Exit nano with Ctrl-X and answer the question for saving with вЂњyвЂќ.ДЄfter the public key is stored on the RevPi, the private key must still find its way into Putty. In Putty (with the nano open), simply right-click in the text area. This works by selecting the public key in puttygen (the contents of the box under вЂњ Public key for pasting into OpenSSH authorized_keys file:вЂњ) and right-clicking and copying it. I copied the public key from puttygen into it. Moving the mouse creates entropy from the PCвЂ™s point of view and contributes to good keys.ДЄfter the key was created, I connected to the RevPi and created a new file for the keys with nano ~/.ssh/authorized_keys2. Just click on Generate and, as you can read, fiddle around a bit with the mouse. For security issues in the experimental stage these are more than enough.

For my current work I left the default settings (RSA and 2048Bit). Putty comes with a small tool called puttygen, which is responsible for key generation. At least for experimental use, you can make your work much easier here by storing a key instead of a password. While working with the RevPi I was annoyed after a short time by having to enter the password in Putty again and again. The possibilities of the Unix world are exemplary here. So if, like me, youвЂ™re annoyed by every job where you have to do exactly the same thing more than twice, youвЂ™ll look for a way to automate such work steps. IвЂ™m sure a certain amount of due diligence is part of it.

Windows users need to add the RSA key to the cache and/or accept and save the host key change.Дepending on your client you may need to click either Accept and Save or Yes, as shown in the images below: Bitvise

You should be prompted to add the key to your known_hosts file, as shown below.

Add the new key to your known hosts with the command:.

This will remove the old key entry for HOSTNAME from your $/.ssh/known_hosts file.

Run this command, replacing HOSTNAME with the name of the host you are connecting to:.

Manually change these keys by following the following instructions for either Unix or Windows. Automatic file transfer set-up dependent on remote host keys are now likely to break and users may encounter error messages. Host keys used by SSH connections have been changed from DSA to RSA.
