Proxies, firewalls, where to find proxies
and check them, other proxy related soft and ANON Remailers
A Proxy is simply a server to connect a users to a network.
Usually it connects to another network (for example, the Internet)
from a local network or a part of it, for example a hospital.
They exist in very diverse capacities and powers,
from proxys to connect a complete government to the
Internet, to one in which the user can have a setup in his house to connect
his brother, his grandmother and the cat to the Internet using a single modem.
At first it doesn't seem like anything
special; nevertheless, due to the architecture (the way the things are made)
of the Internet, these servers can be very useful, contributing security,
speed and privacy to those people who wish to enjoy the Internet without
resigning their "privacy".
If you read the Whats an IP number FAQ, you'd know
how each computer on the Internet is marked with its own special address.
You have probably deduced, (but I will tell you anyway)
that the IP points directly to us. That is, if we are the bad guy on
the computer, it is possible to locate us, because a specific IP at a
specific time is connected to a single person or machine.
And not only when we are the bad guy can we have problems.
Whenever we are connected with another computer (for example a Microsoft page),
the other computer registers our IP and what we have done inside, the pages
we have watched, the files we have taken, etc. etc. Some sites even
deny us access ("you do not have permission...") to certain pages because
we are not from the server's country (the single IP number does not say
anything, but in conjuntion with the DNS or "Domain name system" it indicates
the country and the company).
Here is where the proxy comes in. We have said that these computers
connect several people or machines to the network; that is, that
several machines have the same IP facing the outer world, although for the
proxy each computer continues to have its own unique IP. What
happens if we connect to a server using one of these proxys?
The target server will believe that the downloader was the proxy and not
us, with the proxy acting like a shield.
For example, say our IP is 220.127.116.11 and we want to get
some photos of Pamela Anderson from a site, but we do not want anyone to
know that we have seen those pictures. It's very simple. We say
to the proxy (if the proxy admits calls from the outside), "Please make
a call to the computer X and request the photos from him." If the IP
of the proxy is 18.104.22.168, in the computer which contains the photos,
the lurker IP will be 22.214.171.124 and not 126.96.36.199.
Appears very hard? It is not. All (or almost all)
browsers, like Netscape, Opera or Internet Explorer, allow us to indicate
a proxy for our connections, correctly configuring our browser. We will
surf as always but the navigator gets the pages or files through the proxy.
But the proxy does not serve only for that. Imagine that you
want to download a file from Japan, but your conection is very
slow and you die waiting for it, but when you try to get one page from America
or Europe the speed is superior. Ok, you will try to find a proxy
with a good conection between the target and you, and request
the files through the proxy. Sometimes this system greatly accelerates the
speed of downloading, although at other times it does the opposite.
Thats all there is to it. Unfortunatly, proxies are only available for
HTTP, FTP, but there is also a trick way to use SOCK proxies for NTTP...:-)
All, right so the next step is to find a good fast
working proxy and to set up your browser to work with it.
To learn how to set your browsers with proxies, read the
How to set a proxy FAQ.
PROXIES, PROXY CHECKERS, PROXY RELATED SOFT
and ANON REMAILERS
Why would you want to use a proxy?..check
a few NOTES & TIPS on using proxies:
- when using a proxy, ANY proxy remember that it's usually better not to swim against the current ;-)
as every access is probably monitored in log files.
- DO NOT USE
they are NOT secure proxies, read the
Richard Smith's article
posted on alt.comp.virus.
- for a proxy to be effective, turn OFF ALL
Java, Java Script, Active X and Cookies!
- you can also chain several proxies together-
proxy.name.com:8080/proxy2.name.com with the
name of the port for the second proxy in the port column (do not forget,
proxies are not WWW servers). you can put the proxies in either in the
address/URL field of your browser-
or inside where manual proxy config is
- You actually do not need to visit the
anonymizer or any other proxy, all you need to do
is to precede the *exact and complete*
http://...address you want to visit, writing (even per hand in the
"address" field of your browser)
Sites with Lists of Working Proxies:
Ijs.Co.Nz (and subsequent pages),
wiktor.dk-proxy list.htm , or
for a list of proxies servers by country, go to
list of proxies,
Additional Software for Proxies:
carries the Proxy Hunter, the Proxy Checker, PlooUp, ets
- the a4p shareware will checks the degree of anonimouslity of the proxy you are using,
- the freeware Proxomitron will stop all sorts of info your browsers carelesly tell the outside world, and it act as a proxy too, to set it up, read the
Proxy hunter will find proxies in ANY domain you desire,
- leader.ru-online proxy testers, whois, trace(in russian)
excelent place for proxies, proxy toolz, proxy checkers and MUCH more, or if www.deny.de doesn't work, try
check how anon the proxy you are using really is:
trully anon proxies will NOT show HTTP_FORWARDED or HTTP_X_FORWARDED_FOR variables, HTTP_FROM will show if they can grab your email address from the browser, HTTP_REFERER will show the page you came from,
to see your IP address quick, type WINIPCFG on the START+RUN
MANY places to visit and find out what they say about YOU AND your proxy, some will say your proxy is secure, some won't, so it's YOUR judgment:
- who.htmlin russian
several links to check to see if yor proxy is really ANON
If the proxy is anonymous, it will see the proxy's IP and the text
"anonym" or "none" in green. if it could see the real IP (Start Button/Run/winipcfg to know it) a little red skull, will appear, so you BETTER look for another proxy.
- tamos cgi
- Tiac.net with Java and Java Script tests, refresh tests, ets,
- Shields UP!-will lists your open ports and tell you your computer name on the Net,
- DQ XodoX,
- the GLR proxy check ,
cavency.virtualave.net-a proxy checker and a list of proxies too!,
and Several Remailers you can use to ANONIMOUSLY
the Freedom Remailer?
the Anonimizer remailer
the encripted version of the above
use this to post text messages to usenet anonimously
open proxies-use at your own risk!
Privada.net (like anonimiser)
