riaqn / china-dns Goto Github PK

@riaqn 提供的第一版Release 根据README中的运行方法，
ZHINA_TCP_TIMEOUT=2000000 ./zhina-dns < china.txt
返回如下的错误

[ThreadId 1 : Main.main] Error writing log message: Prelude.read: no parse (original message: [ThreadId 1 : Main.main] zhina-dns: Prelude.read: no parse

使用本机stack编译的版本运行
stack exec zhina-dns < ~/china.txt
依旧报上述错误。

This would be three steps:

1. adding AAAA record in the resolve library
2. adding the ability to read IPv6 ranges from china.txt(basically I will copy from iproute package)
3. adding the ability of identifying Chinese IPv6 address.

1. fix several hacking/hardcoding in resolve, so on the resolver side we have better EDNS client.
2. also on the server side, we should add EDNS support someday.

Currently only one upstream server(one for each of Chinese and foreign) is supported, while some users may wish to use a dynamic resolv.conf as upstream. We hope to address this problem.

1. adding resolv.conf support in resolve library
2. adding this to zhina-dns would be quite easy.

Currently only TCP is used for foreign DNS. This is based on the observation that the most widely used proxies(shadowsocks) is STREAM-based(UDP is supported but is proxied via UDP, which is fucked by the QoS of many ISP, making it unusable).

However, some users may have fast and stable access to the UDP 53 port on the DNS server, which invalidates the above concern. Thus, we need to add a command-line switch to switch on foreign UDP upstream.
