Subject: [TOOL] TXDNS 2.1.5. An aggressive multithreaded
	DNS brute-forcer

Hi everyone,

TXDNS [http://www.txdns.net] 2.1.5 is out. This an intermediary release for
the upcoming 2.2 version. This release implements DNS queries against
multiple DNS servers, a more efficient threading algorithm and some minor
bug fixes. 

To use along with the new feature you'll find on the download area a
start-up list of know open/public dns servers that I have extracted from
VivilProject's list of public DNS servers. Bear in mind that I can not
guarantee that all DNS servers will remain open :-) and thus you may come
across with some false-negatives by the time that some of them gets closed
or discontinued. I'll keep an eye on VivilProject web site and and try to
update de list as much as I can. Feel free to report me closed servers or
any new open ones. 

Usage example: 
  > txdns foo.com -rt -bb --min 1 --max 3 -sl dnslist.txt -x 50

Faster DNS servers will place more queries than others, so you may easily
compile a top 10 servers list by sniffing your own traffic. 

At last but not at least, smalllist.txt has been updated and renamed to
namelist.txt. A few more links to public word lists are also available.

Cheers,
