SSH Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

Try to build a k8s test bed cluster with vagrant box, during ssh config phase ssh-copy-id always timeout.

Try to run:

ssh -v vagrant@192.168.0.21

The message show an error message：

Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

Guess the error is related to ssh server, then try to compare the config with another machine that can login with ssh correct.

Finally find that there have a config item PasswordAuthentication in /etc/ssh/sshd_config, the value in vagrant box is no, but the value in another machine is yes

Try to update the value to yes and restart the box, the ssh login worked as expected.
