如何调试ssh隧道 [英] How to debug a ssh tunnel

问题描述

我想在本地机器上设置一个简单的ssh隧道到互联网上的机器。
我正在使用

I want to setup a simple ssh tunnel from a local machine to a machine on the internet. I'm using

ssh -D 8080 -f -C -q -N -p 12122< username> @< ; hostname>

安装工作正常（我认为）导致ssh重新提交我提供的凭据。

Setup works fine (I think) cause ssh returs asking for the credentials, which I provide.

然后我执行

export http_proxy = http：// localhost：8080
和
wget http://www.google.com

Wget返回请求已发送到代理，但没有收到数据。
我需要的是一种方法来查看ssh如何处理请求....

Wget returns that the request has been sent to the proxy, but no data is received back. What i need is a way to look at how ssh is processing the request....

推荐答案

要获取您的SSH连接中有更多信息进行调试，请忽略 -q 和 -f 选项，并包含 -vvv ：

To get more information out of your SSH connection for debugging, leave out the -q and -f options, and include -vvv:

ssh -D 8080 -vvv -N -p 12122 <username>@<hostname>

要解决您的实际问题，请使用 ssh -D 您本质上是设置了一个 SOCKS 代理，我认为默认情况下不支持wget。

To address your actual problem, by using ssh -D you're essentially setting up a SOCKS proxy which I believe is not supported by default in wget.

您可能会喜欢 curl ，通过 - 袜子提供SOCKS suport 选项。

You might have better luck with curl which provides SOCKS suport via the --socks option.

如果您真的需要使用wget，则必须重新编译自己的版本以包含袜子支持。在 - with-socks 之间的某个地方，应该有 ./配置的选项。

If you really really need to use wget, you'll have to recompile your own version to include socks support. There should be an option for ./configure somewhere along the lines of --with-socks.

或者，查看 tsock 它可以拦截传出的网络连接并通过SOCKS服务器重定向它们。

Alternatively, look into tsock which can intercept outgoing network connections and redirecting them through a SOCKS server.
