在IPv4环境下如何访问北邮人PT？

发表于 分类于 
众所周知，身为教育网 PT 站的北邮人是无法通过公网的 IPv4 环境访问的，访问需要使用教育网 IPv6 或者是公网 IPv6，那么如果在仅有 IPv4 的环境下应该怎么访问北邮人 PT 呢？

准备环境：

  1. 一台拥有公网 IP 的 VPS，如 Vultr,Cloudcone 等
  2. 一个搭建在上述VPS上的代理服务，如 SSR,V2Ray
    修改/etc/hosts，在文件的最下面加入两行：
    1
    2
    2001:da8:215:4078:250:56ff:fe97:654d bt.byr.cn
    2001:da8:215:4078:250:56ff:fe97:654d tracker.byr.cn
    然后保存即可，使用 curl -v https://bt.byr.cn，如果返回的内容如下面所示，则说明测试成功：

    此时便可以通过这台服务器上搭建的代理服务访问北邮人PT，注意请设置代理客户端为全局模式，或者将 hosts 中的两个域名加入客户端的代理列表中。
