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.
Not OP but everytime I used the verbose output of ssh it didn't help me one bit. Even adding outrageous verbosity I was still quite confused on what step failed and which didn't.
I'm probably just bad at understanding SSH but i don't know it seems like ssh workflow includes many trial and error until it finds a way to connect.
Imo the verbose output of SSH is often not very helpful if you don't know very well ssh in the first place. Obviously it is still worth a shot and a good advice but don't expect ssh to clearly state what is going on :)
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:

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