ssh client say me Permission denied.(publickey).
I want to install sshd on my server... I started sshd , generate keys for all users,but everytime I has a message on the client
Permission denied (publickey)
I installed pure archlinux system from CD. And have the same problem on the new archlinux system
but i have trouble with a connection to all my archlinux systems,but no trouble for outgoing ssh connections to router on all of these systems
In /var/log/auth.log there is no any line about trying to connect to the server
Code:
user@local ~ $ ssh archserver
Permission denied (publickey).
Code:
ssh -vvv archserver

Under your home directory there will be .ssh/known_hosts file check that. It will have the unique signature for that ip. Try removing the entry for that server.

scp doesn't copy public key to the remote machine,while it is going to use RSA authentication!!!
scp says that
