点击桌面上的Cygwin，注意在win7中一定要以管理员身份运行，否则不能创建sshd服务。输入以下命令
cd /bin
ssh-host-config
zpc@Lenovo-PC ~
$ ssh
ssh.exe ssh-agent.exe ssh-host-config ssh-keyscan.exe
ssh-add.exe ssh-copy-id ssh-keygen.exe ssh-user-config
zpc@Lenovo-PC ~
$ ssh-host-config .
usage: [OPTION]...
This script creates an OpenSSH host configuration.
Options:
--debug -d Enable shell‘s debug output.
--yes -y Answer all questions with "yes" automatically.
--no -n Answer all questions with "no" automatically.
--cygwin -c <options> Use "options" as value for CYGWIN environment var.
--port -p <n> sshd listens on port n.
--user -u <account> privileged user for service, default ‘cyg_server‘.
--pwd -w <passwd> Use "pwd" as password for privileged user.
--privileged On Windows XP, require privileged user
instead of LocalSystem for sshd service.
