go ssh开箱即用，注意几点

package main

import (
   "bytes"
   "fmt"
   "go-test/src/model"
   "golang.org/x/crypto/ssh"
   "log"
)

func  sshAuthMethod(passwd, pkFile, pkPasswd string) (auth []ssh.AuthMethod) {
   // pkfile存在， 就进行密钥验证， 如果不存在，则跳过密钥验证。

   // 密码不为空， 则添加密码验证。
   if passwd != "" {
      auth = append(auth, ssh.Password(passwd))
   }

   return auth
}




func main() {
   model.DbInit("conf.toml.template")
   sshConfig := ssh.Config{
      Ciphers: []string{"aes128-ctr", "aes192-ctr", "aes256-ctr", "aes128-gcm@openssh.com", "arcfour256", "arcfour128", "aes128-cbc", "3des-cbc", "aes192-cbc", "aes256-cbc"},
   }
   //DefaultTimeout := time.Duration(1) * time.Minute


   config := ssh.ClientConfig{
      User: "root",
      HostKeyCallback: ssh.InsecureIgnoreHostKey(),
      //Timeout: DefaultTimeout,   默认0即可
      Config: sshConfig,
      Auth: sshAuthMethod("xxxxx@","",""),

   }

   client, err2 := ssh.Dial("tcp", "192.168.9.107:22", &config)

   if err2 != nil{
      fmt.Println(err2)
   }
   defer client.Close()
   session,err4:=client.NewSession()
   if err4!= nil{
      fmt.Println(err4)
   }
   defer session.Close()



   var b bytes.Buffer    //优先RUN之前
   session.Stdout = &b 


   if err := session.Run("ifconfig"); err != nil {
      log.Fatal("Failed to run: " + err.Error())
   }
   
   fmt.Println(b.String())
