Ssh – Why SSH is asking for the private key password each time

passwordssh

Since yesterday, each time I try to connect to an ssh server, I got asked for my password. What should I do to make SSH not ask for my password each time.

Put your public key in hostnachine:~/.ssh/authorized_keys and make sure it has the appropriate permissions -- chmod 600. See the man page, section AUTHENTICATION, for more details. Note that sshd maybe configured to disallow this method of login although I cannot fathom why.

This can happen on systems with auto-mounted home directories, like in a system with Active Directory or LDAP. Type mount after you login to see if your home directory was auto mounted. Unfortunately, there isn't a way (that I know of) to fix this. Usually, an entire /home directory is mounted, so all user's home directories are available during SSH authentication.

SSH keeps skipping the pubkey and asking for a password

The new openssh version (7.0+) deprecated DSA keys and is not using DSA keys by default (not on server or client). The keys are not preferred to be used anymore, so if you can, I would recommend to use RSA keys where possible.

If you really need to use DSA keys, you need to explicitly allow them in your client config using

PubkeyAcceptedKeyTypes +ssh-dss

Should be enough to put that line in ~/.ssh/config, as the verbose message is trying to tell you.
