我使用一台Mac通过ssh连接到另一台ubuntu电脑，然后ssh很快就会断开连接。
packet_write_wait: Connection to 192.168.1.7 port 22: Broken pipe
从连接到断开只需要很短的时间，只有几秒钟。比如我要输入一个命令“docker container ls”，我还没输入完就断开了。
我查看了 ubuntu 上的“用户”，刚刚用 ssh 登录的用户还在。查看“auth.log”，没有该断开连接的会话的关闭记录。
尝试了“ssh -o ServerAliveInterval = 60 user @ sshserver”和“ssh -o IPQoS = throughput user @ sshserver”，但都没有用。
Mac系统：macOS Catalina 10.15（19A602）Ubuntu系统：Ubuntu 18.04.3
Ubuntu刚刚安装好，安装了openssh-server，没有进行任何其他配置。
