其实我不知道哪些信息是有价值的。我和能成功传输的作了一个对比，似乎差不多。

几个连接都是1500. 我调整了一下docker0 和 veth1aea394 （应该是容器的），并没有解决问题，并且有时会导致在更早的时候卡住。
再次感谢。https://github.com/libra146/docker-topsap/issues/16 参考一下这个 issue，更改一下 mtu 然后 ping 一下试试看？如果是 mtu 的原因应该会在某一个值导致丢包的

1 week ago 根据您的建议，我直接抄了那个issue里的解决方案，可以传输大文件了。
感谢。
我个人不是很懂网络。这里我写一些系统信息供后来者参考。

您好！
我按照您的教程配置以后可以使用ssh连接服务器进行终端操作，但如果使用scp上传较大的文件（没有特别大，~10KB），就会卡死，进度条显示
我的尝试：
您能否给点建议，看还有什么地方可能出问题？
祝好！
