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.

    Can you post the result of the env command as well? It sounds like your config is very minimal, but the fact that it’s looking for a local Unix socket in the strace output is weird.

          Hey that works too! Same effect as my previous workaround, that I just posted yesterday.

          I do have to repeat this command everytime, so I had to put it into ~/.zshrc so it’s executed beforehand in every new terminal.

          It still does feel lile a workaround since it ‘resets’ itself (as I said) with every new terminal.

            So, this is set somewhere in your config files, I think. Maybe try:

            grep -r SSH_AUTH_SOCK /etc
grep -r SSH_AUTH_SOCK ~/.*

            Just to see where it’s being set.
