Functions

func DialWithDeadline

func DialWithDeadline(network string, addr string, config *ssh.ClientConfig) (*ssh.Client, error)

DialWithDeadline works around the case when net.DialWithTimeout succeeds, but key exchange hangs. Setting deadline on connection prevents this case from happening

func NewClientConnWithDeadline

func NewClientConnWithDeadline(conn net.Conn, addr string, config *ssh.ClientConfig) (*ssh.Client, error)

NewClientConnWithDeadline establishes new client connection with specified deadline

Types

type Dialer

type Dialer interface {
	// Dial establishes a client connection to a SSH server.
	Dial(network string, addr string, config *ssh.ClientConfig) (*ssh.Client, error)
}

A Dialer is a means for a client to establish a SSH connection.

func DialerFromEnvironment

func DialerFromEnvironment() Dialer

DialerFromEnvironment returns a Dial function. If the https_proxy or http_proxy environment variable are set, it returns a function that will dial through said proxy server. If neither variable is set, it will connect to the SSH server directly.
