how to increase golang.org/x/crypto/ssh verbosity
问题
我想使用golang.org/x/crypto/ssh编写一个小程序，能够读取与ssh -v输出相当的内容。虽然我能够通过ssh包连接到我的服务器，但我不知道如何启用详细输出或获取其中的所需信息。由于我对golang还很陌生，甚至无法确定是否可能实现。
以下是我目前的代码：
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")
}
请注意，这只是一个连接到服务器的示例代码，并没有启用详细输出。要启用详细输出，你需要使用sshConfig的Config字段中的Logger来设置一个自定义的日志记录器。你可以使用ssh包中的NewClient函数来创建一个带有详细输出的SSH客户端。
英文:
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")
}

作为一个快速的解决办法，你可以打开$GOPATH/golang.org/x/crypto/ssh/mux.go文件，将const debugMux = false改为const debugMux = true，然后重新编译你的程序。
为了看到调试日志，请先让你的程序执行一些操作：
s, err := c.NewSession()
if err != nil {
fmt.Printf("Failed to create session: %s", err)
}
fmt.Println(s.CombinedOutput("hostname"))
英文:
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"))
