Functions

func BastionConnectFunc

func BastionConnectFunc(
	bProto string,
	bAddr string,
	bConf *ssh.ClientConfig,
	proto string,
	addr string,
	p *proxyInfo) func() (net.Conn, error)

BastionConnectFunc is a convenience method for returning a function that connects to a host over a bastion connection.

func ConnectFunc

func ConnectFunc(network, addr string, p *proxyInfo) func() (net.Conn, error)

ConnectFunc is a convenience method for returning a function that just uses net.Dial to communicate with the remote end that is suitable for use with the SSH communicator configuration.

func PasswordKeyboardInteractive

func PasswordKeyboardInteractive(password string) ssh.KeyboardInteractiveChallenge
