[SOLVED] OpenSSH ERROR: Permission denied ( publickey )

an4rki_ · 2022-10-01 13:27:35

Hey Archers!
I am trying to disable clear text passwords for better security for my home server. I have made the following changes to /etc/ssh/sshd_config file on the server. I have not touched any configs on the client side.

Changes Made
PermitRootLogin - changed to no
PasswordAuthentication - uncommented and changed from yes to no

Here's the config file.

Here's the log file.

The ~/.ssh directory has 700 permission and the public key in that directory has 644 permission while the private key has 600.

Edit: When I comment out PasswordAuthentication and then try to ssh from a different terminal, I am not getting the enter passphrase prompt but instead I am getting the enter password prompt.

Client or server? The private key has no business being on the server and the public key needs to be in .ssh/authorized_keysauthorized_keys

See https://wiki.archlinux.org/title/OpenSSH#Checklist and esp. #5

Hey, thanks for the quick reply @seth.

I am talking about the file permissions on the client machine and not the server. And yes, I checked the contents of .ssh/authorized_keys on the server and it does contain my public key.

Then raise the verbosity of ssh on client and server to see why either might not be happy w/ your key (could be incompatible algorithms)

I had saved the key as g0roth_id_ed25519.pub while generating the key pair under the ~/.ssh directory but apparently it was not able to find it. Here's the output after setting the verbose flag. I kept the default name i.e. id_ed25519.pub and it worked.
