Hi Group,

I wonder if there is a proxy which is configurable that it rewrites every request to special DNS request and is 
sending and receiving on port 53 UPD/TCP. Additionally there should be a server listening on port 53 UDP answering 
all requests the client is sending.

Background to this question is, I'm currently testing a wireless network which allows traffic on port 53 to every 
server. So why not tunnelling s this way! I don't want a tool where I need my own DNS server with authority of a 
domain and so! 

Cheers -j

I'm workin' about this... I'm developing two daemons which allow to
tunnelize data through DNS updates and queries.

It's called SecSyslog and it has been presented at SADFE last year. Some
modifications to the protocol allowed me to produce my thesis, presented
last tuesday. My work is mainly based upon Dan Kaminsky's researches.

And yes, with some assumptions one can transmit data without authority
on the DNS server, implementing SecSyslog with minimal differences.

My 2 cents.
