why can't I connect to my ssh server UNLESS I enter eval "$(ssh-agent -s)" first?
(lemmy.dbzer0.com)
I have my own ssh server (on raspberry pi 5, Ubuntu Server 23) but when I try to connect from my PC using key authentication (having password disabled), I get a blank screen. A blinking cursor.
However, once I enter the command eval "$(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.
okay I tried that, using -i to specify private key. I get the same thing: blank / blinking cursor. When I use verbose -v flag, I see that in both (using -i, the config file, and originally) cases (I see about 50 lines) it ends with these two lines:
where (etc) is some redacted text. It seems the server is ACCEPTING the key, which is nice. But then it's still a blinking cursor...
Check if it is true. In the server logs.
I'm not sure which logs I can and should check, but when I listen to this:
sudo tail -f /var/log/auth.logI only get this right after I ctrl+C on my blank / blinking cursor screen. (Did this 3 times in a row.)
Where MY_PUBLIC_IP is redacted. I'm not even sure why my public IP is showing. I connect locally. But ports are forwarded, yes.
Using
sudo journalctl -u sshd -fdoes not seem to output anything...That's only part of the handshake. It'd require agent input around that point.
