Question

我正在尝试进入一组不支持常规shell的服务器。 / crypto / ssh库不适用于这些，因此我正在通过exec.Command使用直接ssh。

现在的问题是，如果我通过-o StrictHostKeyChecking=no，该命令就会挂起，即： exec.Command("ssh", "-o", "StrictHostKeyChecking=no", config.User + "@" + host)

但适用于简单的

exec.Command("ssh", "-T", config.User + "@" + host)

完整的代码块在这里（基本上只需要像这样将命令通过管道传递到ssh连接

echo hostname | ssh -T -o StrictHostKeyChecking=no user1@db1-ar6.name.local：

p1 := exec.Command("echo", config.Command)
p2 := exec.Command("ssh", "-o", "StrictHostKeyChecking=no", config.User + "@" + host)
//p2 := exec.Command("ssh", "-T", config.User + "@" + host) //doesn't work

fmt.Println(p2) //checking output

var stdout, stderr bytes.Buffer
p2.Stdout = &stdout
p2.Stderr = &stderr

p2.Stdin, _ = p1.StdoutPipe()       // p1 pipe to p2 ssh


err1 := p2.Start()  // start ssh command but dont wait for it to finish
if err1 != nil {
  return errors.Wrap(err1, "starting ssh session failed")
        }

err2 := p1.Run()    // run pipe command and wait for it to finish
if err2 != nil {
  return errors.Wrap(err2, config.Command+" failed", )
         }


err3 := p2.Wait()   // ssh wait for pipe to close
if err3 != nil {
  return errors.Wrap(err3, "ssh wait failed")
         }

输出为，并且等待功能失败：

&{/usr/bin/ssh [ssh -o StrictHostKeyChecking=no user1@db1-ar6.name.local] []  <nil> <nil> <nil> [] <nil> <nil> <nil> <nil> <nil> false [] [] [] [] <nil> <nil>}

Go exec.Command在StrictHostKeyChecking = no上挂起
