ssh 問題

root_man

ssh client 生成 key key_pub

拷貝到server.  ssh-keygen -if key_pub > key_ssh_pub
cat key_ssh_pub > /root/.ssh/authorized_keys
chmod 700 /root/.ssh
chmod 600 /root/.ssh/authorized_keys
修改sshd_conf文件 增加 PubkeyAuthentication yes
重啟 service sshd restart

PuTTYgen -> load key -> generate putty private key -> key_putty
putty用key_putty登陸server

死活提示 server refused our key
