SSH Authorization, problem, verbose inside
by hkjz from LinuxQuestions.org on (#5DXYF)
i have a problem, connecting to server via ssh.
i already tried manipulating file below on many ways
Code: nano /etc/ssh/sshd_configi expect that the problem may lay in the names of my private key, since i gave them special name - `dog`
Code:ssh-keygen -f dog -t rsashort:
