What is a proxy server?

A proxy server is a kind of buffer between your computer and the Internet resources you are accessing. The data you request come to the proxy first, and only then it transmits the data to you.
--------------------------------------------------------------------------------------
What is an anonymous proxy server?

Anonymous proxy servers hide your IP address and thereby prevent your from unauthorized access to your computer through the Internet. They do not provide anyone with your IP address and effectively hide any information about you and your reading interests. Besides that, they don't even let anyone know that you are surfing through a proxy server. Anonymous proxy servers can be used for all kinds of Web-services, such as Web-Mail (MSN Hot Mail, Yahoo mail), web-chat rooms, FTP archives, etc.
---------------------------------------------------------------------------------------
What types of public proxy servers exist?

1. Transparent - HTTP proxy server reveals all. Usable only for transfer speed improvement.

2. Anonymous - HTTP proxy server doesn't send any variables with your real IP to host, but it sends variables indicating that you are using proxy.

3. High Anonymity - HTTP proxy server doesn't send ANY variables indicating that you are using proxy server to host.
----------------------------------------------------------------------------------------
Why should I use proxy servers?

1. Transfer speed improvement. Proxy servers accumulate and save files that are most often requested by thousands of Internet users in a special database, called 'cache'. Therefore, proxy servers are able to increase the speed of your connection to the Internet. The cache of a proxy server may already contain information you need by the time of your request, making it possible for the proxy to deliver it immediately.

2. Security and privacy. Anonymous proxy servers that hide your IP address thereby saving you from vulnerabilities concerned with it.

3. Sometimes you may encounter problems while accessing to web server when server administrator restricted access from your IP or even from wide IP range (for example restricting access from certain countries or geographical regions). So you try to access those pages using an anonymous proxy server.
------------------------------------------------------------------------------------------
What is a public proxy server?

It is a proxy server which is free and open for everybody on the Internet. Unfortunately most of them are not anonymous.
-------------------------------------------------------------------------------------------
What is a pay proxy server?

iPrive - a pay proxy server with plenty of features. Effective for personal use, when your Internet activities are not involved in very active surfing, web site development, mass form submitting, etc. In short, iPrive is the best solution for most of Internet users. Ultimate protection of privacy - nobody can find out where you are engaged in surfing. Blocks all methods of tracking. URL Encryption protects you from your own ISP. Web Based - does not require any program installation or a configuration on your computer.
---------------------------------------------------------------------------------------------
What is a free proxy checker?

Free service trying to provide daily updated list of public HTTP proxy servers. Usually provide small list of proxies with low percent of functioning servers due to hosting restrictions on CPU time (they simply can't allow themselves to check many proxies every second especially in parallel).
computer.
---------------------------------------------------------------------------------------------
What is a pay proxy checker?

AtomInterSoft - a pay database of free public proxies. Solution for pros. A place where a huge list of proxy servers has been compiled. It uses the latest algorithms for collection and sorting of proxy servers, checking them for anonymity, SSL-based access and other properties.
----------------------------------------------------------------------------------------------
What is SOCKS?

SOCKS is a networking proxy protocol that enables hosts on one side of a SOCKS server to gain full access to hosts on the other side of the SOCKS server without requiring direct IP-reachability. SOCKS is often used as a network firewall, redirecting connection requests from hosts on opposite sides of a SOCKS server. The SOCKS server authenticates and authorizes requests, establishes a proxy connection, and relays data between hosts.

There are two major versions of SOCKS:
SOCKSv4 (http://www.socks.permeo.com/AboutSOCKS/SOCKSvE.asp)and SOCKSv5.(http://www.socks.permeo.com/AboutSOCKS/SOCKSvF.asp)

For more information, see:
SOCKS Overview (http://www.socks.permeo.com/AboutSOCKS/SOCKSOverview.asp)
SOCKS FAQ (http://www.socks.permeo.com/TechnicalResources/SOCKSFAQ/SOCKSGeneralFAQ/index.asp)
-----------------------------------------------------------------------------------------------------------------------
Are there dangerous proxies?

Yes.

First, there are servers of goverment organisations (FBI, CIA, NASA etc.) and organizations working close with federal/state and corporate law enforcement.

Second, there are hackers.

And don't believe those proxy checkers (even pay ones) telling you "we filter all dangerous proxies". It's impossible. Nobody can tell you if that proxy you are using is monitored or not.

Of course we've blacklisted all IPs and IP ranges we found to be dangerous (in fact hundreds of ranges).
-------------------------------------------------------------------------------------
What should I do if the access to some web-sites is restricted for me (by my provider, administrators etc) ?

Use a proxy server ! Its principle of operation allows you to surf on many sites you have been forbidden. Certainly, the provider can find out, that you are using proxy and also restrict access to this proxy server. However there are many free proxies servers on the Internet, and you can easily take another proxy, and continue to travel on the sites closed for you.
-------------------------------------------------------------------------------------------------
Is it legal to surf through open proxies?

As far as we can tell, the answer is yes. The primary argument against open proxies is that their owners may not have intended for them to be used by the public. However, by running a service on a machine accessible to the public, without restricting access to that service, the machine's administrator is implicitly consenting for that service to be used by the public. A proxy server is just like a web server, an FTP server, or any other net service: if it's running and accepting connections, it's fair game. The internet is a public network.

With regard to US law in particular, 18 USC 1030 (which covers computer-related fraud and theft) applies only when the user has knowingly accessed a computer without authorization or has knowingly exceeded his authorized access on that computer. Because an open HTTP proxy, by default, allows connections and use of the service by anyone in the world, the proxy's administrator has essentially "authorized" everyone to use the service. There's no intentional bypassing of security taking place. Just as you don't need Google's express written permission to connect to google.com, you don't need a proxy admin's express written permission to use his open proxy server.
----------------------------------------------------------------------------------------------------------------
But there is already the corporate proxy server in my company !

In this case you can use: 1)anonymizers (CGI proxy) 2)a chain of proxy servers
----------------------------------------------------------------------------------------------------------------
What is proxy chaining ?

A Proxy chaining is merely connecting to more than one proxy and then to your intended destination. You can use as many proxy servers as you can or want. The more you have, the more anonymous you will be.
----------------------------------------------------------------------------------------------------------------
How does using the proxy server affect the performance of Netscape (or Internet Explorer)?

It may take slightly longer to connect over a dialing line if you are using the proxy server setup. That's because your browser must first load the proxy instructions before it proceeds with the session. It is also possible that, as more and more resources come to be protected by the proxy server, it may slow your browser's performance a little.
----------------------------------------------------------------------------------------------------------------
Do I need to do anything to exit the proxy server?

Yes. When you have finished using the proxy services, remember to turn the proxy server settings off. If you do not, all further internet transactions will be filtered through the proxy server. Unnecessary use of the proxy server may slow down your internet access
----------------------------------------------------------------------------------------------------------------
What is PAC ?

PAC stands for a Proxy Auto Config file. It does the same thing as you when configuring Web browsers to use a proxy server. But it makes the browser to load its proxy configuration information from a remote javascript file, but not from the information you enter directly.
-----------------------------------------------------------------------------------------------------------------
Do I need to perform the browser configuration every time I go online?

No. Configuring your browser is a one-time event -- unless you change to a new browser or to a new proxy server.
------------------------------------------------------------------------------------------------------------------
Why it can be faster to surf via proxy ?

Some proxy server does web caching thus gives you extra WWW (and partially FTP) speed. Idea is very simple: client program tries to retrieve the requested document not from the real location, but from cache/proxy. If cache/proxy does not find this document in its cache space it downloads it and returns to the client.
------------------------------------------------------------------------------------------------------------------
I want to scan for some IRC proxy - How?

Download IRC proxy checker: (check under proxy tools) Import last proxy list, define IRC server and time and scan for working proxies. And remember that you must try to find proxies on other ports than : 23 , 1080 (socks) ,80 - 81 ,3128 , 8080 ,8081. Because almost all IRC server scan now for proxy with ports above.
-------------------------------------------------------------------------------------------------------------------
The program is not able to work with proxy. What should I do ?

Making a program to use a proxy server depends on the type of proxy. For SOCKS proxy you?ll need SocksCap (check under proxy tools). It will socksificate any program i.e. redirect all requests to the socks proxy. For HTTP it?s necessary for the proxy server to support HTTPS protocol. Install a local SOCKS proxy server and using Socks2HTTP redirect all requests to it on HTTP proxy.
-------------------------------------------------------------------------------------------------------------------
If I am using a Proxy Server does this prevent me from downloading files?

Using a Proxy Server will not prevent you from downloading.
--------------------------------------------------------------------------------------------------------------------
My IPS is AT&T/MSN/America Online (AOL)/CompuServe/Prodigy and I can not use proxy !

Web browsers provided by these Internet Service Providers may not work properly with the Proxy Server.
--------------------------------------------------------------------------------------------------------------------
I don't know what is the best anonymous proxy, level 1 or level 5 ?

Level 1 but the primary question here what you understand under truly anonymous proxy. Difference between proxy level 1 or 2 and the other proxies is that proxies level 1,2 are indistinguishable from a browser and the other proxies spills more and more variables. The most important thing is of the proxy spills the really ip or not. Generally proxy level does not matter if proxy not spills the real ip.
---------------------------------------------------------------------------------------------------------------------
Are IRC proxies only proxies for IRC?

No. IRC proxies are actually proxies that support connect method. All IRC proxies you can use to connect anonymously to the ftp servers, ICQ....

[erni07]

Maksudnya gimana sih?

[OIR]

Yg gimana itu yg mana mbak/mas?
Jangan semuanya gak jelas lho

[bgung]

proxy server kalo diibaratkan kepada manusia apa sama kek make topeng gitu ya?? jadi "wajah asli" gag dikenali oleh "administrator"

atau kah. misal gi mau bertandang ke tempat temen, cuman ortu dari temen tersebut gag ngebolehin ketemu. nah, trus minta tolong pembantu untuk manggilin temen qta tu n ketemuan di suatu tempat. pembantu lagi berperan jadi proxy

yang mana yang lebih tepat kira-2. bis dikasihkan pencerahan?? atau bisa diibaratkan keduanya??

[MAS]

ya gitu juga bisa deh ...

[KIN]

pada umumnya, berapa lama cache dalam proxy itu disimpan dan atau dihapus?

kalo susah jawabnya ya based on personal experience aja deh

[MAS]

ga ada patokan tuh ampe berapa lama,ada yg menit,jam hari bahkan minggu bulan dan tahun !!!

tergantung kebutuhan aja,walo secara default adl 72 jam pada rata2 server proxy yg ada

[KIN]

[Ndo..Q]

kalo di warnet nih...sebenernya butuh apa engga sih proxy? AFAIK dia mampu mengatur lalulintas network secara adil...

AFAIK di sma aku,,pas 1 kompie on dia dapet jatah hampir 100%..tapi pas ada 40 kompie yang on si proxy mengatur masing2 dapet 2.5%...jadi kan enak engga ada yang dirugikan meski client pake semacam accelerator buat browsing maupun download...cz pada umumnya warnet engga pake proxy n kalo ada 1 client yang buka berat / download dia bakal dapet bandwidth yang besar...laennya akan kecil.. maklum korban bandwidth kecil...

nanya dong.. di kantor gw banyak bgt web yang di block...
udah coba juga browse via anonymous proxy gratisan tapi kayaknya yang di block itu content categorynya (ato gimanalah ga terlalu ngerti) tapi ada message begini

you have rquested access to a website or content currently restricted
category : Anonymous Proxy...

Penasaran banget deh... tolong yah... gimana sih caranya...

Thx loh...

wah..proxy servernya udah dipinterin ama administratornya....mana anonymous proxy juga diblokir...ya udah engga bisa apa2 lagi deh....

[jeff rizuki]

ada bedanya ga proxy server ma proxy?

[MAS]

proxy server = penyedia hardware buat proxy nya.dan proxy nya itu sendiri adl aplikasi yg berjalan di server.

kira2 begitu kali yah

[jeff rizuki]

kalau ip2 yg bisa didapatin di internet secara bebas
itu juga proxy ya?

[MAS]

IP nya berformat bagaimana? ya utk bisa dikategorikan proxy kan kudu ada keterangan...di pake di port brp dlsbnya.

ga ngasal tentunya kan?

[jeff rizuki]

yg kayak diatas tu proxy ya?

[MAS]

[emmet24son]

Btw, ada yg pernah nemu nggak, software yang buat otomatis ganti proxy saban 10 menit (misalnya)? Rata-rata pan kita musti ganti manual tuh proxy-nya?

[andreya]

cara bikinya gemana
buat warnet bisa?

[mrbego]

[mrbego]

coba pake open proxy https://ninjacloak.com
