示例1: setProxyCommand

	// TODO(mjs) 2016-05-09 LP #1579592 - It would be good to check the
	// host key of the controller machine being used for proxying
	// here. This isn't too serious as all traffic passing through the
	// controller host is encrypted and the host key of the ultimate
	// target host is verified but it would still be better to perform
	// this extra level of checking.
