simple-dns

A simple regular-expression based DNS server, based on twisted.

Usage

hosts 文件里指定要劫持的域名，格式为：

#IP            Domain
127.0.0.1     www.alipay.com
127.0.0.1     /.*?\.alipay\.com/

支持正则表达式，用/包围。
非劫持域名会向上级 DNS Server 递归查询，返回正确的 IP 地址。

Sample

Attacker(127.0.0.1):

sudo python dns.py

Target(127.0.0.1):

➜  ~ nslookup 
> server 127.0.0.1
Default server: 127.0.0.1
Address: 127.0.0.1#53
> test.website
Server:		127.0.0.1
