1、运行ssh-host-config
这里需要注意的是标红部分，输入的用户名或密码要符合计算机的用户名或密码策略（尤其是公司有权限限制的电脑）。
$ ssh-host-config *** Query: Overwrite existing /etc/ssh_config file? (yes/no) yes *** Info: Creating default /etc/ssh_config file *** Query: Overwrite existing /etc/sshd_config file? (yes/no) yes *** Info: Creating default /etc/sshd_config file *** Info: Privilege separation is set to yes by default since OpenSSH 3.3. *** Info: However, this requires a non-privileged account called 'sshd'. *** Info: For more info on privilege separation read /usr/share/doc/openssh/README.privsep. *** Query: Should privilege separation be used? (yes/no) yes *** Warning: sshd is in /etc/passwd, but the *** Warning: local machine's SAM does not know about sshd. *** Warning: Perhaps sshd is a pre-existing domain account. *** Warning: Continuing, but check if this is ok. *** Info: Updating /etc/sshd_config file *** Query: Do you want to install sshd as a service? *** Query: (Say "no" if it is already installed as a service) (yes/no) yes *** Query: Enter the value of CYGWIN for the daemon: [] *** Info: On Windows Server 2003, Windows Vista, and above, the *** Info: SYSTEM account cannot setuid to other users -- a capability *** Info: sshd requires.

最后一句话说明ssh服务安装成功。
2、启动 sshd服务
$ net start sshd
The CYGWIN sshd service is starting.
The CYGWIN sshd service was started successfully.
3、本地ssh连接测试
$ ssh localhost The authenticity of host 'localhost (::1)' can't be established. ECDSA key fingerprint is 84:4f:13:3e:f7:55:3f:a2:d2:50:26:f5:1b:72:85:fb. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts. toughhou@localhost's password:
4、用SecureCRT连接cygwin本机
连接地址: 127.0.0.1
连接端口: 22
用户名密码： 自己机器的用户名及密码，不是之前配置的cyg_user123
