SSH into a Synology NAS using a key
Posted: Friday 23 June 2017 15:13
Hello,
After several researches on Google, I try to connect through ssh from my Raspberry (with Domoticz) to my Synology NAS with a key to log without entering a password.
What I've done unitl now allow me to connect from Putty to my NAS without password (with key created thanks to Puttygen) -> Thus, I conclude that on NAS side, everything is correctly configured.
However when I try to connect to my NAS from my Raspberry through ssh, it still ask me the password, as you can see below :
Do you know what I can do to resolve this problem please ?
If you need more log or information, I will give it.
Thanks in advance for your help.
