I have my own ssh server (on raspberry pi 5, Ubuntu Server 23) but when I try to connect from my PC using key authentication (having password disabled), I get a blank screen. A blinking cursor.
However, once I enter the command eval "$(ssh-agent -s)" and try ssh again, I successfully login after entering my passphrase. I don’t want to issue this command every time. Is that possible?
This does not occur when I have password enabled on the ssh server. Also, ideally, I want to enter my passphrase EVERYTIME I connect to my server, so ideally I don’t want it to be stored in cache or something. I want the passphrase to be a lil’ password so that other people can’t accidentally connect to my server when they use my PC.
Well, you have configuration and flag options to define what is it supposed to be trying to use. What order, I think too. But definitely understanding SSH a little bit will make the log more understandable. As with everything tbh :D
This likely isn’t helpful but it isn’t meant to be a shitpost. However, I will point out this literature:
SSH, The Secure Shell: The Definitive Guide, 2nd Edition

Other commenters clearly know more than me about tbs ssh, so I’ll otherwise remain silent.
