DialSSHTimeout - It is impossible to read timeout

[lpzgithub]

I used the DialSSHTimeout for testing read Timeout. I intentionally send the server not to know the message and produce the reading timeout.But the reality is that read has not Timeout. I found that the data it read was the data returned by KEEP_ALIVE.

The interval of KEEP_ALIVE is half of the reading of Timeout.

go func() {
		ticker := time.NewTicker(timeout / 2)
		defer ticker.Stop()
		for range ticker.C {
			_, _, err := t.sshClient.Conn.SendRequest("KEEP_ALIVE", true, nil)
			if err != nil {
				return
			}
		}
	}()

func (c *deadlineConn) Read(b []byte) (n int, err error) {
	c.SetReadDeadline(time.Now().Add(c.timeout))
	return c.Conn.Read(b)
}

ok, thanks. close this.
