eDexter IS:
a software filter and a personal server that works in two ways:
First, in conjunction with Hosts and a PACfile (If the PAC option is enabled),
or in conjunction with Hosts alone, it will allow you to filter out sites that
you consider objectionable, and do not wish to access. It can block an
acceptable site from sending you images from an unacceptable site server
(where your presence can be recorded), or from being redirected to an
objectionable site. You decide what is objectionable, based on entries in
Hosts or PAC files.
Second, it will act as a limited personal web server, which will operate only
on your local machine (IP 127.0.0.1). Whenever the filter has been activated,
instead of the unacceptable data being retrieved from the web, eDexter will
intercept the search and act as if IT were the site, and quickly return a
small image to be inserted in the present loading page. Your page loads
faster, with less objectionable material on it. No time is wasted searching
for the site (DNS search), waiting to connect, and downloading the request.
Also no tracking software at the offsite location has been given any
information about you. Your privacy is improved.
Using Hosts as a filter, without eDexter, will cause your browser to a wait
for the file to load, from your own machine, and because the file is not
there, your browser will eventually time out. This may take 10-30 seconds or
more and would be repeated for each requested image on that page. If there are
20 loads from an objectionable site on one page, you will have to wait 20
times as long. Using eDexter will almost eliminate that delay.
--- --- --- ---
eDexter IS NOT:
eDexter is not able to block all objectionable sites. You can block a lot, if
you keep the filters up to date. As more sites are added to the internet, new
domain names are in use, and the objectionable ones need to be added to the
files. Companies change their names frequently, and use other means to get
more proficient in defeating 'blocking' software.
eDexter does not protect your computer from viruses, worms, or other nasty
programming, that can be 'piggy backed' in on images or other data. It does
not protect you from hackers, who may wish to 'look' at your machine.
eDexter Personal Edition is not able to be used by any machines other than
your local machine. If you are a corporate, educational, or government entity
you must purchase eDexter. A multi-user version of eDexter that allows
machines to use a single copy of eDexter for filtering is available for
purchase.
Use of a Firewall and up-to-date AntiVirus Software is strongly recommended.
Even if you don't use this product.

FEATURES OF eDEXTER (Version 1.33):
Logging (Against our better judgement)
PAC (proxy auto configuration) support.
Select images folder
Edit Hosts file
Edit pac file
Auto start in stealth mode
hide/show system tray icon
Installer version creates menu and startup shortcuts
PACKAGED AS:
dexterln.exe (131kb, 134,633bytes) includes install
>>>>> filename.ext (xxxKb, xxx,xxxbytes) no install option
files include:
dxeula.txt releasenotes.txt
eDexter.exe image.x.gif (x is single digit 0-6)
hosts.dxt.txt pacdata.txt
uninstall.exe (installer version only)
--- --- --- ---
PROXY AUTO CONFIGURATION (PAC):
Using this option allows eDexter to filter with only a few entries in the
Hosts file. The Hosts.Dxt.txt file is a sample of the needed minimum entries.
The file pacdata.txt contains the necessary entries to filter a large number
of sites, deemed worthy of filtering, by the author. You will need to modify
the filter rules in pacdata.txt in order to achieve the same level of
filtering achieved using the Hosts technique. PAC filtering is not system-
level and may not prevent as many eMail web-bugs or advertisements as the
Hosts method. eDexter's PAC file support is accomplished without additional
software on your computer.
---->>>> NETSCAPE AND MOZILLA USERS:
Some browser/platform combinations may not be able to use the PAC option.
Other netscape or mozilla users may be able to use PAC in a reduced mode. READ
'UNRESOLVED ISSUES:' BELOW
---->>>> INTERNET EXPLORER USERS:
Because of the problems with the Netscape and Mozilla browsers, the file
pacdata.txt has been set up with certain features nonfunctional. Although you
can run IE with this file as is, you should remove the restrictions. Full
instructions are contained in the pacdata.txt file.
--- --- --- ---
TO INSTALL:
If you are running an existing version of eDexter please exit it prior to
running the Installer or copying the new version to your eDexter folder.
---->>>> Version with installer.
Double-click the downloaded file. It will by default be installed into
c:\Program Files\Pyrenean\, but you could select any other folder. You will be
asked whether you wish to create menu entries, and/or a startup shortcut.
---->>>> Without installer.
Create a folder, preferably c:\program files\pyrenean\ and move or copy the
download into this folder. Double click on the file, and it will expand. No
shortcuts, or menu entries will be made. You may wish to create a shortcut or
two. See Start menu and System Tray Menus for additional details.
Make sure that there is a file called hosts in your c:\windows directory.
(Hosts is a file with no extension, not a folder). If you are going to use the
PAC (proxy auto configuration), you may wish to rename and save the existing
hosts file as hosts.txt and then rename the new eDexter file hosts.dxt.txt
(found in the newly created eDexter folder) to hosts, and then move or copy it
into your C:\Windows directory.
The distribution's hosts.dxt.txt file contains only two host name entries.
Hosts filtering offers system-level privacy protection for e-mail and programs
other than your browser. PAC filtering is not possible for all programs that
access the Internet. If you are currently using a Hosts file, it is acceptable
to leave your existing entries and only add the filtered.by.edexter entry. The
PAC and this rule will help your browser filter more sites that your existing
hosts may not currently filter.
---
TO SET UP PAC:
Leave the pacdata.txt in the eDexter folder.
---->>>>For Netscape and Mozilla:
READ 'UNRESOLVED ISSUES:' BELOW Open
browser, select Edit|Preferences - Advanced - Proxies select Automatic Proxy
Configuration and enter the following into the text window
[url]http://filtered.by.eDexter/eDexterAuto.pac[/url]
---->>>>Internet Explorer:
Open browser, select Tools|Internet Options|Connections If you use DSL/Cable
or LAN click 'LAN Settings' If you use Dialup, select your ISP and click
'Settings' on the new page select 'Use Automatic Configuration Script' and

you reinstall eDexter.
If you used PAC, open your browser and remove the Automatic Proxy
Configurations that were made during the PAC setup
--- --- --- ---
GENERAL NOTES:
HOSTS vs PAC:
The Host file is like a local telephone directory for IP
addresses, a weird number like 216.65.377.84 These are the real identifiers of
computers on the internet. URL's and Domain Names are only for us humans.
When you enter a location address by site name, or when a loading page directs
you to another site by name, your computer will check Hosts first. If Hosts is
not found, or if the name is not listed in Hosts, your computer will then link
to a D(omain) N(ame) S(erver), a name/IP number matching service, to find the
IP number. If you have a Hosts file, the matching IP is returned and is
directly addressed without the DNS search. With the host filtering method used
by eDexter, named sites are given the number 127.0.0.1, which is the default
IP for your own computer.
Instead of going to the web for the requested page, image, etc. your browser
will look for your computer to supply the requested item. Without a program
like eDexter, the search would eventually time-out, and your browser would
stall. eDexter is set up to intercept this search and quickly return a small
image which will be placed in your browser.
However, Hosts blocks entire Domain names. If [url]www.netscape.com[/url] (used for
example only) was found in hosts, and was set to 127.0.0.1, then you would not
be able to contact any address starting with [url]www.netscape.com[/url].
PAC works similarly. It still requires a Hosts file, but only two entries are
really necessary. They should be in this order. Any other entries should
follow.
(Minimum Hosts for PAC operation)
127.0.0.1 localhost
127.0.0.1 filtered.by.edexter
the remainder of the data used for filtering is found in the pacdata.txt file,
and is a much smaller file than the nonPAC Hosts. PAC will allow a filter
match on a DNS, URL, or IP. The PAC files can block certain addresses, unless
they meet additional filtering criteria.>>>>> You could block access to
[url]www.netscape.com[/url], but allow access to [url]www.netscape.com/downloads[/url].
FIREWALL:
eDexter does not open a port to the outside world,, nor does it need one. It
works entirely within your local IP address 127.0.0.1. This version does block
port 80 to the outside world. However, if you connect to the Internet you
should consider obtaining a personal firewall, such as ZoneAlarm. Most
firewalls, including ZoneAlarm allow you to specifically block external access
to your computer FROM the net, and to allow only those programs that you
specifically permit, to connect TO the net. For example, ZoneAlarm will allow
you to deny eDexter's access to the Internet.
If you use a firewall, configure the firewall to disallow eDexter's access to
the internet but to enable eDexter's access to the local machine. Since
eDexter only operates on your localhost IP-address of 127.0.0.1, eDexter may
be able to operate even if your firewall is set to block eDexter from a
connection with your local machine. If your firewall acts in this fashion, you
may as well set your firewall to disallow both local and internet connections.
It then doesn't make any difference.
DNSKONG:
You do not have to run DNSKong with this version of eDexter. However, as the
author of DNSKong, we are biased towards it and suggest you might find it
useful. It offers security at the system level, and can block programs that do
not use the PAC file approach. eDexter is completely compatible with DNSKong
except if you use the PAC option. To use PAC, first edit the named.txt file in
DNSKong, and add
filtered.by.edexter
Shared versions of DNSKong, such as Private Networks or Enterprise Edition
should not add the filtered.by.edexter entry in named.txt.
LOG:
This version of eDexter enables logging. A log file may be used to violate
your privacy and to track your browsing, both by other people at your
computer, or by others that you let in past your firewall. You do have a
firewall, right? We don't use the log ourselves and we recommend that you not
use it, or that you periodically clear it out.
IMAGES:
eDexter can supply one of 6 gif images, at random, to your browser. Other gif
images are available and can be substituted for the included ones, but as they
will probably be distorted to fit into various size ad frames, smaller is
better. If you choose not to use images, eDexter will display a small
transparent image instead.
eDEXTER SERVER VERSION:
eDexter Server version (commercially available version) can accept connections
from the Internet. If you are using this version you should establish firewall
rules to restrict access to eDexter as you need. For example, if you are using
eDexter server and DNSKong on a private network you should restrict access to
eDexter (and DNSKong) to your local net. And remember to set up those firewall
rules!
VERIFY OPERATION:
You can verify eDexter's operation by using the command-line, netstat -an,
this will show something similar to:
C:\>netstat -an
Active Connection
Proto Local Address Foreign Address State
TCP 0.0.0.0:135 0.0.0.0:0 LISTENING
TCP 0.0.0.0:135 0.0.0.0:0 LISTENING
TCP 0.0.0.0:1026 0.0.0.0:0 LISTENING
TCP 0.0.0.0:1028 0.0.0.0:0 LISTENING
TCP 0.0.0.0:1029 0.0.0.0:0 LISTENING
TCP 127.0.0.1:80 0.0.0.0:0 LISTENING
You will also notice other connections to 127.0.0.1:80. This indicates that
eDexter is operating and serving properly.
INI FILE:
Created upon install
Note: Command-line parameters override .ini file entries.
C:\WINDOWS\EDEXTER.INI (typical entry)
[Preferences]
HideOnStart=1 #>>>>> Start invisible? (0 - no, 1 - yes)

UNRESOLVED ISSUES:
POSSIBLE BROWSER INCOMPATIBILITIES WITH PAC (Proxy Auto Configuration)
Version 1.34 has been verified with Mozilla, Netscape versions 4.3 -4.7 and
Internet Explorer 5-6. However, some versions of netscape, or mozilla, may not
work with all PAC options. Even when browsers work with the PAC option it only
offers limited versatility. To prevent problems, the pacdata.txt file, as
delivered, comes with certain features disabled, to prevent causing problems
when installed on netscape or mozilla machines. Read the documentation
contained within pacdata.txt for details.
PAC works best in Internet Explorer. The file pacdata.txt should be modified
to enable full use as needed. IE users should read the documentation contained
within pacdata.txt and follow the additional steps to obtain full
functionality.
INTRANET AND NAT ROUTER ACCESS:
By default, eDexter's PAC filters block numeric IP access. If you are using a
web configurable NAT router such as a LinkSys Cable Modem, you will need to
set the PAC filter rules to allow access to the internal IP for the Cable
modem (generally , 192.168.1.1). If you are also accessing internal (intranet)
web servers by IP number you will need to allow access to those IPs as well.
Our observations are that only Internet Explorer functions properly with
passing network IP rules (+N) in the PAC data file.
