Key-Based SSH Permission denied (publickey) Ubuntu 12-04
- by user125176
I have configured sshd to accept key-based ssh logins with LogLevel on DEBUG, and uploaded my public key to ~/.ssh.authorized_keys, where permissions are set as:
700 ~/.ssh
600 ~/.ssh/authorized_keys
From root, I can su - USERNAME. From the client I get Permission denied (publicly). From the server Here's how it is telling me that it "Could not open authorized keys '/home/USERNAME/.ssh/authorized_keys': Permission denied".
Client protocol version 2.0; client software version OpenSSH_5.2
