nc：代理错误：“HTTP/1.0 403 禁止”

我正在使用 Ubuntu 13.10 x86_64。我无法通过代理 ssh 到远程主机。

当我发布时：

ssh -vl hackep6t 162.251.80.25

我得到了这个输出：

OpenSSH_6.2p2 Ubuntu-6ubuntu0.1, OpenSSL 1.0.1e 11 Feb 2013

请帮忙。

您似乎正在通过 HTTP 代理（端口 3128 上的 squid）进行连接，但 nc 的默认连接协议是 SOCKS5。我认为您需要在 ssh_config 中添加-X connect语句ProxyCommand，以使 nc 通过 HTTP 与您的代理进行通信。请参阅man nc以了解详细信息。
