<h2>Overview</h2>
<p align="left">ProxyTools is a package of Perl network utilities
designed mainly to assist those whose Internet access is censored, unreliable,
or otherwise damaged. Uncensored access is provided to any outside service
required (Usenet News, Web browsing, IRC, Socks etc.). Setup requires installation
of Perl and some modules; this is doable by even a novice MS Windows user
with email instruction, allowing help to be provided to those inside these
countries from expert users outside. </p>
<p align="left">In pursuit of this rather non-specific goal, some
interesting network utilities have already been produced. We think the code
is interesting in itself, useful in other areas, and would welcome contributions
to the overall sum of ideas, concepts and ideals expressed in these tools.
</p>
<p align="left">The project is of interest to the following groups
of people: </p>
<ul>
<li> those who live in Internet censoring countries (or corporations,
schools, universities) such as the Middle East (United Arab Emirates, Kingdom
of Saudi Arabia, Kuwait, Syria), China, Burma, etc. </li>
<li> those who would wish to assist those in the group above. </li>
<li> those who are interested in Perl code dealing with many aspects
of networks at the socket level, and transactions using HTTP proxies.
One tool in this project offers a 'failover' capability, and intelligent
choice, between various censor-bypassing strategies and network paths, offering
the user a robust, uncensored connection even in a low bandwidth, unreliable,
packet filtered and proxy-poor environment. </li>
<li> those who administer the firewalls which do the censoring, and
those who might be considering this. </li>
<li> those who are just curious about the current techniques used by
the first group above. </li>
</ul>
<h2>Tools</h2>
<p align="left">The project distribution contains the following tools:
</p>
<h3>localProxy (<a href="lpScreenShot.jpg">screen shot</a>)</h3>
This is essentially a character switch, with some interest in the content
switched. Normally run on the user's computer (but runnable on a Unix
ISP shell outside the user's firewall) this application provides a user
with localhost services to use which implement censor avoidance strategies
in the background. A front end GUI is included which allows convenient
control of the localProxy engine. A single 'AutoConfigure' button allows
even a novice user to map his local firewall rules and create a configuration
file which describes his network environment, specifies proxy capabilities
which may be used to enable (by default) uncensored HTTP proxy and Usenet
News services; selection of this configuration will cause LP to build and
run the configuration. LocalProxy will build a running configuration based
on a database of usable hosts and proxies, applying several sources of information
relevant to accessible hosts, services, firewall rules and firewalled subnets.
LocalProxy runs this configuration and makes connections for the user, learning
to use the fastest and most reliable of the censor-avoidance strategies
and multiple proxy hosts/chains available. The application maintains (and
displays) a 'useful data speed' for each level of the 'user'->'strategy'->'host'->'host'->website/service
chain, to assist the user with configuration. The choices made by localProxy
in switching each request is based on these speeds, ensuring localProxy
avoids non-working strategies/hosts, and ensuring maximum use of the available
'uncensored bandwidth'. Failover capabilities and robustness are built in,
so that users need not frequently update the database of hosts whenever one
dies, becomes blocked, or is temporarily down.<br>
<br>
LocalProxy (excluding Perl modules) is approximately 6000 lines of commented,
debugged Perl code now. Worth a look, just for the spectacle!<br>
<p align="left">Implemented strategies so far, are: </p>
<ul>
<li> use of lists of available external proxies which are accessible
on ports which are not blocked to the user (usually non-standard port
HTTP proxies) </li>
<li> use of lists of available external TCP/IP bouncers (redirectors,
relays, ...) accessible on ports not blocked to the user, usually on shell
accounts </li>
<li> use of lists of local proxies which are insecurely configured
to allow creation of tunnels via CONNECT to external proxies/services on
ports which would be otherwise blocked (port 80, 3128, 8080, 119 etc.)
</li>
<li> use of various URL encoding mechanisms to evade regexp based censoring
(many of these are from Rain Forest Puppy's Whisker).</li>
<li>use of various CGI proxies (which need not rewrite links).</li>
<li>fragmentation of the URL request over TCP packets.
</li>
</ul>
Possible future strategies:
<ul>
<li>built-in Socks 4, 5 (LP is already able to abstract an external
Socks proxy to provide an accessible, localhost Socks4 proxy) </li>
<li> SSL</li>
<li>Triangle Boy client<br>
</li>
</ul>
<h3>statProxy</h3>
A tool to test various aspects of a proxy's function to allow a user to
determine it's usefulness for his purposes. It scans ports on the proxy
if required, tests for CONNECT tunneling capability, censoring, anonymity,
speed, Socks capability etc. The output format is suitable for use by 'mergeHosts'
to merge these test results into the hosts database automatically.
<h3>sortProxy</h3>
A simple sort and merge utility for lists of hosts. A fast, parallel DNS
forward and reverse lookup is done on each entry to produce a standard
format output. Dupes are recognized by IP address and removed. The output
format is suitable for piping to both findProxy or statProxy.
<h3>findProxy</h3>
This tool scans web pages, local files, bulletin boards, mailing lists etc.
for likely looking proxy entries and tests them. This uses LWP, so it's
slower than statProxy (which uses socket level code). It's useful for it's
extensive proxy entry recognition ability (roughly done with Perl regexps)
and it's final test for censoring by the tested proxies.
<h3>master</h3>
This tool is intended to analyze the user's network environment and produce
an XML configuration file for use by the other tools to aid the user in
choices of proxies and strategies. The firewall rules are analyzed by direct
testing, DNS servers are verified, localhost Internet interface IP address
is established and confirmed and all is written to the configuration file
for use by localProxy at build time. All operations are done in portable
ways.
<h2>Purpose</h2>
<p align="left">The reason for going public with these tools is to
ensure a wide distribution to those in need, and to elicit ideas, and comments,
from the networking community. These tools have been completely developed
in an environment consisting of myself (network/proxy consultant) and a group
of naive users. It is likely that the Internet community would be able to
add new perspectives to the project.</p>
<p align="left">Comments and feature suggestions, as well as code,
are welcome here. </p>
