Automatic dialing isn't working any more. How do I fix it?
</h3>
<p>
Some browsers (such as MSIE-4) can be configured to dial your
<small>ISP</small>
automatically when you click on a link,
but this feature gets disabled if you specify a proxy running on your
own computer
(with address
<big><kbd>localhost</kbd></big>
or
<big><kbd>127.0.0.1</kbd></big>)
because these addresses don't require dialing.
The
Internet Junkbuster
knows nothing about dialing, so it doesn't work.
To make automatic dialing work,
make up a name such as
<big><kbd>junkbuster.ijb</kbd></big>
and use that name in the proxy settings
instead of
<big><kbd>localhost</kbd></big>,
and then add the line
<big><kbd>127.0.0.1 junkbuster.ijb</kbd></big>
to the file
<big><kbd>c:\windows\hosts</kbd></big>
(if there already is a line beginning with
<big><kbd>127.0.0.1</kbd></big>
just add
<big><kbd>junkbuster.ijb</kbd></big>
at the end of it.)

<p>
A binary is currently being supplied with the source code,
but if you prefer to compile it yourself here is the likely procedure.
Most of these steps are repeated in our checklist for

<br><ol  type="1">
<li>
<a name="zip">First</a>
<a href="ijb20.zip">click here to download the zip file</a>

in the lines related to Win32.
Then type:
<br>
&#160;&#160;&#160;<big><kbd>nmake</kbd></big>
<br>
This should create an executable called
<big><kbd>junkbstr.exe</kbd></big>.

How do I check that the proxy is working?
</h3>
<p>
Pick a page from somewhere (such as your bookmarks, or just one
that your browser was pointing to)
and
<b><font face="arial, helvetica">
Reload</font></b>
it.
If you get a message along the lines of ``server not responding,
using cached copy instead,'' see the advice
<a href="ijbfaq.html#responding">above.</a>
If the page reloads OK, check that your browser is actually
talking to the proxy by going to
<a href="http://internet.junkbuster.com/cgi-bin/show-proxy-args">http://internet.junkbuster.com/cgi-bin/show-proxy-args</a>
or any
<small>URL</small>
ending in
<big><kbd>show-proxy-args</kbd></big>
(as described
<a href="ijbfaq.html#show">below</a>,
the proxy should intercept the request.)
When you see ``Internet Junkbuster Proxy Status,''
you'll know it's working.

<h3><a name="chain" href="/cgi-bin/gp?pg=ijbfaq&pr=chain"><img border=0 width=14 height=14 src="/images/fb.gif" alt="&lt;Feedback&gt"></a>&#160;
How and why would I have this proxy chained with other proxies?
</h3>
<p>
You may need the 
<a href="ijbman.html#forwardfile">forwarding</a>
feature to ``daisy chain'' the
Internet Junkbuster
to another proxy, perhaps an
<a href="ijbfaq.html#anonymizing">anonymizing</a>
proxy to
<a href="ijbfaq.html#conceal">conceal</a>
your
<small>IP</small>
address,
or a
<a href="ijbfaq.html#cache">caching proxy</a>
from your
<small>ISP</small>,
or a
<a href="ijbfaq.html#firewall">firewall</a>
proxy between your company and the outside world.
Version 2.0
can be even configured to forward
<a href="ijbman.html#forwardfile">selectively</a>
according to the
<small>URL</small>
requested:
for example, connecting directly to trusted hosts,
but going through an anonymizing or firewall proxy for all other hosts.
<p>
<a name="administrator">Network administrators might use it to provide</a>
transparent access to multiple networks without
modifying browser configurations.
<a name="direct">Most browsers also provide a way of</a>
specifying hosts that the browser
connects to directly, bypassing the proxy. Some provide a method for
<a href="ijbfaq.html#Automatic">Automatic Proxy Configuration.</a>
A well written
Internet Junkbuster
configuration can be much more flexible and powerful.
<p>
<a name="example">An</a>
<small>ISP</small>'s
caching proxy
would typically be called something like
<big><kbd>cache.your-isp.net:8080</kbd></big>
(as described on you
<small>ISP</small>'s
web page);
you would put this information in your
<a href="ijbman.html#forwardfile">forwardfile</a>
as described in our manual.
Your browser would be configured to
the
Internet Junkbuster
for
<small>HTTP</small>
and Security Proxies as before,
but you probably want to tell it to use the caching proxy
for
<small>FTP</small>
and other protocols.
<a name="nonlocal">If your</a>
<small>ISP</small>
is running
the
Internet Junkbuster
for you,
they have probably already decided whether to chain with a caching proxy.

<h3><a name="socks" href="/cgi-bin/gp?pg=ijbfaq&pr=socks"><img border=0 width=14 height=14 src="/images/fb.gif" alt="&lt;Feedback&gt"></a>&#160;
How does the Internet Junkbuster work with SOCKS gateways?
</h3>
<p>
There is support for some
<a href="http://www.leverage.com/users/tlod/ssockd/ssockd.html">gateways</a>
in
Version <a href="ijbdist.html#c4">1.4</a>
and above.
The gateway protocol used to be specified on the command line;
it is
now specified
in the same file as
<a href="ijbman.html#forwardfile">forwarding.</a>
Note that the browser's proxy configuration must
<em>not</em>
specify a
<big><kbd>SOCKS</kbd></big>
host;
it should specify the proxy as described
<a href="ijbfaq.html#set">above.</a>
</p>

<h3><a name="plain" href="/cgi-bin/gp?pg=ijbfaq&pr=plain"><img border=0 width=14 height=14 src="/images/fb.gif" alt="&lt;Feedback&gt"></a>&#160;
How do I configure it to be just a plain old proxy?
</h3>
<p>
To get the proxy to do as little as possible (which means not deleting any
sensitive headers), place in your
configuration file the following three lines (each ending in a space
then a period) to stop it changing sensitive headers:
<br>
&#160;&#160;&#160;<big><kbd>referer .</kbd></big>
<br>
&#160;&#160;&#160;<big><kbd>from .</kbd></big>
<br>
&#160;&#160;&#160;<big><kbd>user-agent .</kbd></big>
<br>
&#160;&#160;&#160;<big><kbd>cookiefile mycookiefile</kbd></big>
<br>
The fourth line is also needed to specify a
<a href="ijbman.html#o_c">cookiefile</a>
that might be called
<big><kbd>mycookiefile</kbd></big>
containing a single line with a
<big><kbd>*</kbd></big>
