I have been unable to access servers via SSH after a recent upgrade to Windows 11.
I keep getting a permission denied (publickey) error.
I have tried regenerating new public keys with ed25519 instead of the deprecated rsa and I still get the same error.
I have seen answers alluding to file permissions but am afraid am not sure what files they are referring to.
The files that they are most likely referring to are typically the .ssh folder itself (this folder can be found in your home directory) and the contents within. Here's a table for recommended permissions on those files and folder.
| Element | Permission |
|---|---|
| .ssh directory | 700 ((drwx------) |
| public keys | 644 (-rw-r--r--) |
| private keys | 600 (-rw-------) |
| authorized_keys | 600 (-rw-------) |
| known_hosts | 600 (-rw-------) |
| config | 600 (-rw-------) |
