如何提高golang.org/x/crypto/ssh的详细程度

i wanted to use golang.org/x/crypto/ssh to write a little program which is able to read the equivalent to ssh -v output. While i am able to connect via the ssh package to my server i have no idea how to enable verbose output or get to the desired information in it. As i am new to golang i am not even able to decide if it is possible at all.

Here is my code so far

package main

import (
    "fmt"

    "golang.org/x/crypto/ssh"
)

type SSHClient struct {
    Config *ssh.ClientConfig
    Host   string
    Port   int
}

func main() {
    sshConfig := &ssh.ClientConfig{
        User: "your_user_name",
        Auth: []ssh.AuthMethod{
            ssh.Password("your_password"),
        },
    }

    client := &SSHClient{
        Config: sshConfig,
        Host:   "example.com",
        Port:   22,
    }

    client.test()
    _, err := ssh.Dial("tcp", "example.com:22", sshConfig)
    if err != nil {
        fmt.Printf("Failed to dial: %s", err)
    }

}

func (client *SSHClient) test() {
    fmt.Println("test")
}

    As a quick hack you can open $GOPATH/golang.org/x/crypto/ssh/mux.go file, change const debugMux = false to const debugMux = true and recompile your program.

    In order to see the debug logging make your program do something first:

    s, err := c.NewSession()
    if err != nil {
        fmt.Printf("Failed to create session: %s", err)
    }
    fmt.Println(s.CombinedOutput("hostname"))
