我无法通过 SSH 连接到远程主机,但仅限于我的家庭网络(提供商)。如果我在另一个网络(我在同一个城市的朋友 - 不同的提供商),连接就完美了。Ping 到服务器(在我家)有效。我也只有这台服务器才有这个问题。如果我尝试从我的家庭网络连接到其他主机,它可以工作。我该怎么办?

以下是尝试创建隧道的方法。

  • intermediary是您信任为您进行转发的机器
  • remote是您要访问的机器

    ssh -N -L 20000:remote:22 user@intermediary
    

完成此操作后,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将转发给的intermediaryremote
