示例1: setProxyCommand
// setProxyCommand sets the proxy command option.
func (c *SSHCommon) setProxyCommand(options *ssh.Options) error {
apiServerHost, _, err := net.SplitHostPort(c.apiAddr)
if err != nil {
return errors.Errorf("failed to get proxy address: %v", err)
}
juju, err := getJujuExecutable()
if err != nil {
return errors.Errorf("failed to get juju executable path: %v", err)
}
// 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.

juju, "ssh",
"--proxy=false",
"--no-host-key-checks",
"--pty=false",
"[email protected]"+apiServerHost,
