使用 Brook Server 和 Cloudfare Warp 解锁 ChatGPT

Updated at: 2025-01-02

背景

因为 OpenAI 在某些地区不可用，还 ban 掉了大部分 VPS 提供商的 IP。这篇文章的目的找个可用的落地 IP 来访问 ChatGPT。

cloudflare warp

以下在全新的 Ubuntu 22.04 上操作并验证可行

curl https://pkg.cloudflareclient.com/pubkey.gpg | sudo gpg --yes --dearmor --output /usr/share/keyrings/cloudflare-warp-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/cloudflare-warp-archive-keyring.gpg] https://pkg.cloudflareclient.com/ $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/cloudflare-client.list
apt update
apt install cloudflare-warp -y
echo y | warp-cli registration new
warp-cli mode proxy
warp-cli proxy port 1080
warp-cli connect
sleep 3
warp-cli status

到这里，你应该有了一个socks5, 127.0.0.1:1080

brook

bash <(curl https://bash.ooo/nami.sh)

nami install brook

测试下 warp 创建出来的 socks5

brook testsocks5 -s 127.0.0.1:1080

可以看出，这个 socks5 只支持 TCP，不能处理 UDP。所以只能让 brook server block 掉 OpenAI 的 UDP，然后将 OpenAI 的 TCP 转发到 Warp 的 socks5.

brook --script /path/to/script.tengo server --listen :9999 -p hello

            s = ss[i] + "." + s
        }
