SSH Connection closed by remote host
提问by Petr P?ikryl
I have problem to connect with SSH to remote host but only on my home network (provider). If I am at another network (my friend in same city - different provider) the connection works perfect. Ping to the server (at my home) works. Also this problem I have only with this server. If I try connect to other host from my home network, it works. What should I do?
我在使用 SSH 连接到远程主机时遇到问题，但仅限于我的家庭网络（提供商）。如果我在另一个网络（我在同一城市的朋友 - 不同的提供商），则连接工作正常。Ping 到服务器（在我家）有效。我也只有这台服务器有这个问题。如果我尝试从我的家庭网络连接到其他主机，它就可以工作。我该怎么办？

Here's how you can attempt to create a tunnel.
以下是您可以尝试创建隧道的方法。
intermediaryis a machine you trust to do the forwarding for youremoteis the machine you're trying to get tossh -N -L 20000:remote:22 user@intermediary
intermediary是您信任的机器，可以为您进行转发remote是你想要到达的机器ssh -N -L 20000:remote:22 user@intermediary
Once you do this your local machine will listen on port 20000. When you connect with ssh to this port, on your host, the connection will be forwarded over the tunnel to intermediarywho will in turn forward it to remote.
执行此操作后，您的本地计算机将侦听端口 20000。当您使用 ssh 连接到此端口时，在您的主机上，连接将通过隧道转发给intermediary谁，然后将其转发给remote。
