![SSH 连接成功,输入任意键后断开连接](https://linux22.com/image/1158345/SSH%20%E8%BF%9E%E6%8E%A5%E6%88%90%E5%8A%9F%EF%BC%8C%E8%BE%93%E5%85%A5%E4%BB%BB%E6%84%8F%E9%94%AE%E5%90%8E%E6%96%AD%E5%BC%80%E8%BF%9E%E6%8E%A5.png)
当我从笔记本电脑连接时,我可以成功连接,如果我不输入任何内容,连接将保持打开状态。但是,任何按键都会导致连接中断,并显示以下消息qpacket_write_wait: Connection to {ip} port 22: Broken pipe
当我搜索此错误时,所有结果都与不活动有关。在我的例子中,它不是不活动,而是发送到服务器的任何击键。
我可以连接网络上的其他计算机并发出命令。我已经通过 Ubuntu bash 终端使用 Ubuntu 16.04 Desktop 和 Win 10 进行了测试。其他机器和我的笔记本电脑之间的唯一区别是它们是有线的,而笔记本电脑是无线的。
以下是使用时连接和按键的输出ssh -vvv

我不知道为什么这种连接在其他机器上有效,但在笔记本电脑上却不行。任何帮助或指导都非常感谢。
