配置免密登录
1)修改C:\ProgramData\ssh\ssh_config文件

PubkeyAuthentication yes
AuthorizedKeysFile %programdata%/ssh/administrators_authorized_keys

2)拷贝C:\ProgramData\ssh\ssh_host_rsa_key为C:\ProgramData\ssh\administrators_authorized_keys
3)下载ssh_host_rsa_key和ssh_host_rsa_key.pub文件，放到其他机器的C:\Users\用户名\.ssh目录中并重命名为id_rsa和id_rsa.pub

测试其他机器免密ssh/sftp登录
