README
Are you a power-user with 5 minutes to spare? Do you want a faster internet
experience?
Try out namebench. It hunts down the fastest DNS servers available for your
computer to use. namebench runs a fair and thorough benchmark using your web
browser history, tcpdump output, or standardized datasets in order to
provide an individualized recommendation. namebench is completely free and
does not modify your system in any way. This project began as a 20% project
at Google.
namebench runs on Mac OS X, Windows, and UNIX, and is available with a
graphical user interface as well as a command-line interface.
Requirements:
* Python 2.4 - 2.6. If you are using Mac OS X or Linux, this is
built-in. Otherwise, visit http://www.python.org/
--[ quick use guide ]---------------------------------------------------------
namebench comes with two interfaces: a simple graphical interface, and a
more advanced command-line interface. If you have downloaded the versions
for Mac OS X and Windows, you will get the graphical interface by default.
Most people will simply want to run this software with no arguments:
./namebench.py
On UNIX, if you have python-tk installed, a graphical interface will pop up.
If you would like to force use of the command-line, use -x:
./namebench.py -x
If you want to specify an additional set of name services, simply add the IP
to the command-line, or edit namebench.cfg:
./namebench.py 10.0.0.1 192.168.0.1

--[ FAQ ]-----------------------------------------------------------------------
See http://code.google.com/p/namebench/wiki/FAQ for more recent updates.
1) What does 'NXDOMAIN Hijacking' mean?
This means that the specific DNS server returns a false entry when a
non-existent record is requested. This entry likely points to a website
serving a 'Host not found' page with banner ads.
2) What does 'www.google.com. may be hijacked' mean?
This means that when a user requests 'www.google.com', they are being
silently redirected to another server. The page may look like it's run by
Google, but it is instead being proxied through another server. For details,
try using the host command. In this case, this particular IP server is
redirecting all traffic to http://google.navigation.opendns.com/
% host www.google.com. 208.67.220.220
Using domain server:
Name: 208.67.220.220
Address: 208.67.220.220#53
Aliases:
www.google.com is an alias for google.navigation.opendns.com.
google.navigation.opendns.com has address 208.67.217.230
google.navigation.opendns.com has address 208.67.217.231
3) What does 'google.com. may be hijacked' mean?
The same as above, but it is a rarer condition as it breaks http://google.com/
4) What does 'thread.error: can't start new thread' mean?
It means you are using too many threads. Try restarting namebench.py with -j8
5) What does 'unhealthy: TestWwwGoogleComResponse ' mean?
It means the specified nameserver was too slow to answer you. If all of your
nameservers are timing out, try restarting namebench.py with -Y 4
