How do I shut down the proxy (to restart it)?
</h3>
<p>
It depends on your platform. Under Windows, use
<b><font face="arial, helvetica">
Ctrl-Break</font></b>
in the 
<small>DOS</small>
window or
the old three-fingered salute of
<b><font face="arial, helvetica">
Ctrl-Alt-Delete</font></b>
and select
<b><font face="arial, helvetica">
End Task</font></b>.
Under
<small>UNIX <a href="legal.html#not_our_trademark">&#174;</a></small>
you'll need to
<big><kbd>kill</kbd></big>
the
<b><kbd>junkbuster</kbd></b>
process.
<a name="pid">If you don't know the process number to give to</a>
<big><kbd>kill</kbd></big>, try this:

What do advertising companies think of this kind of technology?
</h3>
<p>
We've seen only a few public comments from the advertising industry on this,
other than
<a href="links.html#adverse">SEC filings.</a>
First, the president of the Internet Advertising Bureau told
<a href="new.html#Rich">CNET</a>
that he wasn't worried by banner blockers.
Second, after the Federal Trade Commission's
<a href="ftc.html">workshop</a>
where we gave a live demonstration of our proxy before
many eminent representatives of the industry,
the
<a href="self.html#dma">Direct Marketing Association</a>
made the following
statement in the closing paragraphs
of their
<a href="http://www.ftc.gov/bcp/privacy/wkshp97/comments2/dma027a.htm">summary comments</a>
to the Commission.
<blockquote>
Clever shareware developers have come up with products that
can obliterate cookies and advertisements for those consumers
who have these concerns.
The Internet is a market that is so democratic and flexible
that it is easy for companies and software
developers to respond to a perceived market need. 
</blockquote>
Their attitude seems to be that they would prefer that
people use technical solutions
to protect their privacy than have protections
imposed by legislation or government regulations.
So, do you perceive a market need?
Then here are some ways to flex your democratic muscles.

Should we provide the Internet Junkbuster for our employees?
</h3>
<p>
That depends. Try this quick three-point test.
<br><ol  type="1">
<li>
<a name="waste">Do you want to spend your communications budget</a>
on bandwidth that wastes your employees' time by forcing them to wait
for a lot of annoying distractions while they're trying to
do their jobs?
<li>
<a name="surveillance">Do you want current and potential vendors</a>
to know quantitative details about the
<a href="ijbfaq.html#agent">software and hardware platforms</a>
that you have?
<li>
<a name="intelligence">Do you want your competitors to be able to</a>
<a href="cookies.html">track</a>
exactly which of your
employees are checking out their web sites?
</ol>
If the answer to all three questions is yes,
then you probably don't have any need for this kind of product.

<p>
Yes,
<a href="/cgi-bin/gp?pg=ijbfaq&pr=commercial">ask us</a>
for a quote on a maintenance contract with your choice of
phone and email support,
hard copy documentation,
source code and pre-compiled binaries on tape or disk,

We also offer consulting services to help set up ``stealth browsing''
capabilities to help reduce the footprints left while doing competitive
analysis and other Web work where confidentiality is critical.

I run an ISP. What issues should I consider before offering it?
</h3>
<p>
Many
<small>ISP</small>s
who offer the proxy to their customers have told us that
most of their customers are 
delighted with it
(although one reported that a customer complaint that without banner ads,
surfing was like reading a novel: we recommend making it optional).
Many
<small>ISP</small>s
like it because it reduces bandwidth requirements.
To help get you started,
here's a checklist we've developed from working with a few
<small>ISP</small>s.
You may think of more,
and we'd be interested if you're willing to
<a href="/cgi-bin/gp?pg=ijbfaq&pr=isps">share them</a>

But it would probably be safer to put an entry in your name server
and call it something like
<big><kbd>junkbuster.our-isp.net.</kbd></big>
If running several proxies, you could either use different ports
on the same machine, or if you have
the opportunity to distribute the load over
a few machines 
you could
use different hostname aliases such as
<big><kbd>banner.junkbuster.our-isp.net</kbd></big>,
<big><kbd>lynx.junkbuster.our-isp.net</kbd></big>
and
<big><kbd>oneway.junkbuster.our-isp.net</kbd></big>

What's a Proxy Server Server and how can I make money as one?
</h3>
<p>
Other organizations with web presence and some bandwidth to spare
can set up as
<i><dfn>Proxy Server Servers</dfn></i>
<!-- Aside: All this, and... -->
(<small>PS<sup>2</sup></small>s).
The idea here is to allow users to choose their proxy configuration,
and provide it to them on a semi-permanent basis.
Users would fill in a form specifying what options they want in
their proxy,
possibly even at a very high level, such as
``no ads''
or ``no nudity.''
This information is sent to a
<small>CGI</small>
script that
configures a proxy, starts it running, and returns its address and port number
(possibly along with configuration instructions for the browser
that the user specified.)
<p>
<a name="revenue">Users</a>
could be charged
a subscription fee,
or the service could be thrown in free in the hope of
improving customer retention for some existing business
(which is what
<small>ISP</small>s
are doing).
It might be possible to make money by
inserting new ads in the holes left where others were blocked,
but the original owners might object.
<small>PS<sup>2</sup></small>s
could differentiate themselves
by providing frequently updated and comprehensive
blocking of ads, or of offensive material based on their own grading system.
Some content providers might do it for the chance to be the
only company that the consumer permits to set cookies.
(Identification could even be done via cookies,
but this might not be popular with the kind of user who wants a proxy.)
<small>PS<sup>2</sup></small>s
might sell specific or aggregate information about their
users' browsing habits,
so the agreement with users on whether they are permitted to do this
would be important to both sides.

Where can I get an example blockfile that stops most ads?
</h3>
<p>
The sample blockfile we provide blocks almost nothing,
and we do not publish blockfiles that stop almost all banner ads.
But others have; you can find them by
<a href="http://www.altavista.com/cgi-bin/query?pg=q&what=web&fmt=.&q=%2Bjunkbuster+%2Burl%3Ablocklist">asking Altavista.</a>
You can add any part of the new file to your old one
(probably called
<big><kbd>sblock.ini</kbd></big>
if you haven't changed the default name in the latest version)
or your just replace it completely.
You
<a href="ijbfaq.html#cover">probably</a>
don't need to restart the proxy.
