have you tried turning it on and back off again

ufoludek 2022-08-18 16:49:13
Instead of shouting it doesn’t work you could just type “how to start ssh server [distro name here]” on google

Yes, and systemctl restart

oh, you’re not getting authenticated when logging in

smol_mazunki 2022-08-18 16:52:17
that’s the sshd server responding to your ssh request with “yo, pls can you confirm you’re who you say you are”
smol_mazunki 2022-08-18 16:52:40
throw in a -vv there to see what’s going on
smol_mazunki 2022-08-18 16:52:49
it will tell you what keys it’s trying, and which ones it’s refusing
smol_mazunki 2022-08-18 16:53:36
have you told git to grant access to $USER’s public key?

It’s trouble. If sshd starting from command line:
debug1: Server accepts key: /home/user/.ssh/id_rsa RSA SHA256:LyZwuuY4bTecXd4+LPpmc+CneBTr2lkyUjq5A8QBEmw agent
debug3: send packet: type 50

min 2022-08-18 16:56:15
It’s not trouble of a client
min 2022-08-18 16:56:31
Server started from systemctl not works
min 2022-08-18 16:56:47
It send type 51
smol_mazunki 2022-08-18 16:56:56
this is a sane output http://ix.io/47X8

what are the journalctl logs saying about it?

smol_mazunki 2022-08-18 16:58:53
is sshd receiving the key?

we can clearly see the sshd server accepting the connection, but is waiting for authentication after i accept the request
smol_mazunki 2022-08-18 17:01:54
after finally accepting the authentication, it opens the tty
smol_mazunki 2022-08-18 17:03:48

we can also see this happening in the logs
