$ cygrunsrv.exe -S sshd # 启动 SSH服务
14. 安装完成后,检查一下系统服务中是否有 CYGWIN sshd 服务, 无启动帐号e69da5e6ba907a686964616f336.
15. 检查系统用户 sshd 是否已启用, 并属于管理员组.
16. 一切正常,即可启动ssh服务. 登录的用户名是sshd, 密码是 sshd用户的密码.
注意: 使用 windows 用户本地认证
mkpasswd -l > /etc/passwd 使用windows 用户的密码
mkgroup -l > /etc/group 使用windows 用户组
配置完成后，你可以使用SecureCRT或者 putty等软件登陆连接ssh
问题描述：
在来Win7下Cygwin中，使用ssh localhost命令，出现Connection closed by 127.0.0.1的问题。
解决方案：
1、开始——源运行百——services.msc
2、右键CYGWIN sshd——属性——登录选项卡——选择“此账户”——浏览——高级度——立即查找——选择你的问账户名（必须为管理员权限）——输入密码（必须要有，空密码不接受）——确定。
3、重启CYGWIN sshd服务即可。
这样就以你的账户的名义启动了这个服务。而后ssh localhost成功。
这样做答的一个缺点可能是你要给电脑设个密码。
win7下卸载cygwin:1.停止cygwin的服务，主要是个sshd服务，通过命令net stop sshd可以停止，还可以在zdwindows服务里找到它右键点击停止服务
2.删除cygwin的服务目录，另外检查下载windows c盘用户目录下包含cygwin的用户目录，如果有也删除掉，回删除创建的快捷方式
3.在计算机管理->本地用户组下删除cygwin创建的用户
4.打开注册表，删除一些内容
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\sshd
HKEY_CURRENT_USER\Software\Cygwin
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cygwin
5.以上步骤完答成后重启计算机即可。
以系统管理员身份启动cygwin
