spood is a spoofing DNS proxy with a vaguely obscene name. All in Erlang.

WHAT IS IT

spood is a DNS proxy that listens for requests on localhost and proxies the requests by spoofing the packets from the IP addresses of other clients. spood might be useful if you're using a DNS tunnel like sods:

2. Test it:

    www.google.com  canonical name = www.l.google.com.
    Name:   www.l.google.com
    Address: 173.194.33.104
   

TODO

• support multiple name servers

• add ability to turn on/off debug output

• add sanity checks on sniffed DNS packets, like checking domain
