(unrecognized proxy protocol) connection from Bitvise Tunnelier http代理设置

配置 Bitvise Tunnelier 时候，发现出错。

提示有：

baidu 了一下，找到了解决办法:

在使用我配置的ssh的时候，直接就可以上网的，这是为什么？按照错误提示看，是代理协议不识别，不支持客户端的代理协议，客户端可能要求普通的http协议来连接。

出现这种错误的原因，是ssh应该被作为socks代理而不是http代理来使用，而我们一般的设置中，如果在http代理中填入了http的代理地址和端口，浏览器就会优先使用

http代理，这与ssh冲突，所以才协议识别失败。所以在IE中设置如下：

於是我們去google這個問題，發現遇到這個問題的時候好多人都是建議用Privoxy或者Polipo軟件做中轉，把tunnelier默認提供的socks代理轉換成http代理。其實大可不必，大家可以看看bitvise官方的一個技術支持的回答，地址在這裏：https://fogbugz.bitvise.com/default.asp?Tunnelier.2.8457.1
註意這句：”What you need to do is change that applications to use SOCKS instead.”
所以，我們只需要去掉瀏覽器設置中的”對所有協議使用相同的代理服務器設置”選項，然後只在Socks代理服務器中填寫即可。下面的例子是在Chrome瀏覽器的switchy proxy插件中的設置：
