What is a proxy server?

A Proxy (proxy server) is a server that acts as mediator between the client (the computer of a user) and server (the computer on the other ends of network connection on which the information requested by the user appears for example web server site.) When clients request data from an Internet resource, traffic goes from your web browser/application first through the proxy before it reachs the requested sources and back through the proxy. Then the proxy will transmit the data (information) to you.

Why I need to use a proxy server?

1. Transfer speed improvement. If the file you requested was received before to your proxy server, then proxy server will interrupt this file request and you will receive the file directly from proxy. However need to know, you can got the “speed down” effect. This effect appears when your proxy has long answer time because there is slow connection between you and your proxy server.

2. Security and privacy. Anonymous proxies destroys information about your computer in the requests header. So you can safely surf the net and your information will never be used by hackers and spammers.

3. Sometimes you encounter some problems while accessing to web server (for example, web-chat). You have mistaken while working with some data and / or the server administrator restricted access from your IP. So you can use the anonymous proxy and try to access again.

How can I get fresh proxy server information?

Every proxy server is inclusive of an IP address and a proxy port that is listed next to the address. You can search “free proxy list” on google to get newest proxy servers. Here is a daily updated proxy list I recommend: http://www.aplusproxy.com/proxylist/index.php

How to configure IE 7.0 to use a proxy server?

3. Select the Connections tab and click the button for LAN Settings.

4. Click the radio button for Proxy Server. Type the IP number of the proxy In the Address box, and add the port number of the proxy in the Port box.

5. Click the OK button, then OK again.

Proxy servers are computers that offer a computer network service that allows its clients to connect indirectly to other network services. Proxies that are able to block the offensive web content are called web proxies. Another meaning of web proxies is reformatting the pages for other different operating systems. The internet providers might also set up proxies for preventing the occurrence of the computer viruses or any other hostile content such as spam that might affect your PC.

The special case of web proxies and the most frequently used are CGI proxies. For everybody to understand it is good to be explained that these CGI proxies are web pages that allow users to access other sites through them. These special sites are mostly used to gain access to blocked web sites. This thing is possible because the web proxy servers hide your IP address from any website and might also lead to faster browsing.

Many organizations such as schools or families use a proxy server to enforce acceptable network use policies or to provide security such as anti-virus, anti-malware or anti-spam services.

Anonymous proxy servers are most frequently used because these web servers do not share your IP address or any information about you or your computer. These anonymous proxy servers will protect you from different forms of malware such as viruses or spam.

Another advantage was proved when it comes to the anonymous web proxy server. It is known that these servers work with the help of a virtual database called cache. This memory is used to store the asked information and when that information is needed again there is no need for a new connection. The required information will be restored from the cache memory and this can not lead to anything but an increase of web surf quality and an increase of browsing speed.

These web proxy servers are indicated because it is known that if some sites get your IP and some minimum information about your operating system, hacking might be possible. Hacking will lead to an ongoing block and more than that it may lead to sharing the information from your hard drive and RAM.

More an inconvenience than a risk is the fact that proxy users may find themselves being blocked from certain web sites because numerous sites or forums block the IP addresses that are known to be spammed or trolled.

The good thing is that your IP is not vulnerable by using these web proxies.

Proxy sites are web pages that provide Internet users with the ability to browse web sites that may be blocked by a content filter of some type. By making use of the proxy site as the portal to the blocked site, it is possible to circumvent the work of whatever filter is in place. At the same time, the proxy site also helps to mask the visit to the site, so that there is less evidence that the content filter was not successful in preventing the visit.

How Does A Proxy Site Work?

Essentially, the proxy site will provide the same ability to browse the Internet as any other browser. What is a little different is that instead of being able to conduct general searches for content, a proxy site allows the user to key in a specific web address and be directed to that specific page in a window that resides on the proxy site. This accomplishes two things. First, the window is coded as part of the proxy site address and not the actual web site the user is visiting. Second, any information cached on in the temporary Internet files will appear to be information related to the proxy site, and not the blocked web site.

Why Use A Proxy Site?

One of the legitimate uses of a proxy site is to get around blocked content that may contain one or two words that the filter has identified as inappropriate for viewing. Many companies make use of filters to limit the ability of employees to spend time looking at web pages that are not related to job functions in some manner. This is usually accomplished with the use of key words that programmed into the filter, which in turn blocks any page or site with those words present. While this does block access to a number of sites that have nothing to do with work, they can also inhibit access to pages and glossaries that are designed to be helpful in many job positions.

When this is the case, an employee may choose to use a proxy site to get around the block and be able to get to a page that he or she legitimately needs to view in order to accomplish a work related task. Since using a proxy site does not take much longer than using a browser window, it is much faster than calling technical support and trying to get authorization to remove a given word from the filter list.

Another advantage of using the proxy site is that the IP address of the user is not logged. This can be a great way to get around the proliferation of adware and spyware that is all too often connected to a given web site. Using the proxy site means less cleanup for the virus protection software to handle, and thus less resources required to keep the workstation clear of problems.

Do you have or are you considering setting up a Craigslist proxy? If you have been forced down the road of setting up or looking for your own Craigslist proxy, then these tips may be of use and will help you select the best proxy to use.

Knowing that you need a proxy to post on Craigslist if you are outside of the USA and knowing what to look for in one are two very different things. If you are trying to select the right configuration for your proxy server, make sure it passes all of the below.

* Make sure it is 100% anonymous - Typically, proxy sellers will state in bold letters that their proxies are 100% anonymous. Many use this as nothing more than a tactic to draw in customers. The best way to find out if they are lying or not is by loading up http://www.whatismyipaddress.com and seeing what is displayed. If it shows anything like that you are using a proxy, it won’t work for Craigslist.

* Multiple IPs - You will need multiple IPs. One IP isn’t enough unless you are only posting 1 or 2 ads a day. Check that the proxy provider has no problem with multiple IPs.

* FAST - Typically, you will find yourself using proxies that are so slow, you feel like jumping out a window. So slow in fact that it would take years to do what you need. Check the speed of your proxy by web surfing around or using the “ping” command in the command window. You want a proxy that isn’t slow when web surfing or has around a 200 - 300ms ping time.

Having a proxy server is great and very useful to many people, but be sure to keep the above advice in mind the next time you go looking to setup your own server. If your proxy server doesn’t meet the above criteria, then it is most likely not suitable for posting ads on Craigslist with and should not be used.  You will be much better off by investing in your own Craigslist proxy to post ads with.

By simply looking up the words proxy server on your chosen search engine you might even end up overwhelmed with just how many sites there are. The even better thing about it is that these sites are free to access so you can easily click through them and see how they differ. But before you end up choosing the one you will download, list all of them first and then do some background check. 2. Read forums and reviews – The online crowd is perhaps the best first hand authorities who can tell you on the best proxy server to download. You would surely find it easy to search the web for topics discussing various feedbacks on the proxy server sites which most online users have used. Forums are usually free to access, although you might not get the chance to reply unless you are a registered user.

proxy?

Have you ever come across a problem like whenever you are trying to open a website it is getting blocked and the error message that is showing up is about some content filter which is not finding the contents of the website authentic and viewable?

This is when a proxy site comes into the picture. They allow you to go through the websites overcoming the blocks. Basically the proxy sites are the ones that ids meant for the convenience of the end users. The proxy servers can help you in various ways. They generally work on behalf of the particular allocated clients and also help the users.

Advantages of proxy

You must have heard about the firewalls which often come in between the end user and the source of connection. They filter the contents and then cater then to you. This is basically made to stop the hackers. The proxy server somewhat relates to the same purpose but they work on it in a slightly different way.

They follow the mechanism of storing and then forwarding. They terminate the source internet connection that is supposed to come to the users and creates a separate connection with the destination. The proxy servers are capable of serving a number of users at the same time.

Using a proxy server you can surf the internet without getting in touch with the internet connection directly. This is the reason you can maintain your privacy with the proxy servers. There are many big service providers like VSNL and AOL which employs the proxy servers to serve their customers who opt for the dial-up plans.

Types of proxy

There are various types of proxy servers. Some of the proxy services fall under the firewall services and some of them work independently. Generally there are three types of proxy servers- Generic proxy, Circuit proxy and SOCKS. The generic proxy always comes with the firewall packages and they provide you with a facility of having a local address even if you are in a remote destination.

Their service is often independent of the situations and applications. The circuit proxies can be considered as a particular type of generic proxy. But they are very helpful when you need too interact with multiple clients virtually and access the client’s connection.

The last one SOCKS was launched in the year of 1991. Though this server comes with the facility of various client libraries but there are certain demerits of this proxy.

e you use the Internet, you’re being tracked by both your server and the servers you access. Your ISP keeps logs of your MAC address (your network adapter card’s number) and your private IP address; the rest of cyberspace sees your public IP address assigned by your ISP. Yes, no matter what you do and where you go, your computer trail leads right to your doorstep. Scary thought? Disturbing? No doubt. How Your IP Address Invades Your Privacy Whether or not you’re engaged in illegal or immoral activity, there’s reason to be worried about this lack of privacy on the Internet. Even people who do nothing strictly unlawful deserve privacy. You may be sending an anonymous mail, or having an illicit affair, or visiting websites that your family and friends would be offended by. You may have moved away and parted with friends and just want to check on their blogs without being identified. Perhaps you share an e-mail account with another person and you want to answer mail for them without giving away the fact you are someone/somewhere else. There are all kinds of reasons why being anonymous is important, and they are not all illegal. Unfortunately, you can’t be anonymous without a proxy server that hides your tracks for you. The websites, forums and web mail services you use all log your visits. Even social networking sites do. If you use your office’s network, the administrator keeps records of who uses it and when. Your public IP address may be changeable and have limited details only, but whoever gets past that and sees your private IP address (behind your ISP router) and worse, your Mac address, will be able to identify you. This lack of anonymity not only affects your privacy; it can also be a security threat. Through such details about your computer, it’s possible for a hacker to build a profile of you and gather such critical info as usernames, passwords, phone numbers and credit card numbers. How to Hide Your IP Address with Proxy Servers An anonymous proxy server can protect you from such tracking. There are two kinds of annoymizing proxies. Disgused proxy and elite proxy. A disguised proxy is identifiable as a proxy server by the website you visit, but it still hides your real IP. An elite proxy is cleverly masked to look like a genuine IP address, and it also hides your original IP. The elite proxy is better because it makes you less “suspicious.” How to Use a Proxy Server with Internet Explorer First go to Internet Options – Connections – LAN Settings In the Proxy Server area, check on “Use proxy server for LAN” box. Enter the proxy server in the address field. Enter the port number also in the port box. Click OK to close LAN box and Internet Options box. You’re ready to surf anonymously!

Have you heard the words proxy server or proxy site? If you have, but you do not know what it means you will want to read on. I confess to being a little ignorant in the world of online websites and proxy sites. You see I may be handy at finding things, but that doesn’t mean I understand how it all works. So first of all to understand what a proxy site is you need to know what they are.

A proxy site or server allows you to surf the Internet with a buffer. In other words the proxy server will hide your IP address while providing you with information. Often a proxy server will help you download pages quicker or files with more speed. This is helpful if you like to download music, movies, or other files to your computer and want to remain safe.

Proxy sites are often where you can locate these proxy servers. If you are interested in finding a proxy site you just need to search for them with a search engine. Google or even Yahoo! can point you towards proxy sites. The proxy sites allow you to find a proxy server that will help you remain anonymous online while you are downloading your files.

The benefit of course is the faster speed you can get your downloads. When you spend hours online finding music to download to your phone or MP3 player you want to know that your files are being downloaded as fast as possible. Other reasons or benefits for using proxy sites is the hidden IP address. You can search online while making it difficult for hackers to infiltrate you computer with viruses or other damaging things. Proxy sites have been created to protect you and make downloads move at a better pace. You probably didn’t even know you where using a proxy site when you downloaded music and it gives you two or three places to download from.

he line of defense against spam, email worms and unauthorized emails? SMTP servers employ a mechanism by which those would not get into the system. They use SMTP Proxies. SMTP proxy is basically another server that sits between the mail sender and the recipient. SMTP is a protocol that stands for Simple Mail Transfer Protocol. This defines the rules for sending and receiving messages. The SMTP proxy does a number of useful things, like filtering and load balancing, and has a number of advantages. The SMTP proxy provides connection management. This server can impose a rule on the number of active connections given to clients. As a client, you can probably have one active connection at a time. This means that you can only send a message one at a time. This kind of rule solves the threat of the DoS, or the denial-of-service, attack. A virus that is capable of DoS will request more than the required number of connections, and eventually use up all the connection resources of that particular server. With all the resources gone, no more clients can access that server. The proxy will limit the number of requested connections thereby making the virus as less likely of a threat. In the end, the system will still have enough resources for other clients. The SMTP proxy provides bandwidth throttling. This mechanism limits the amount of data traffic at a particular time. This prevents server crashes. You probably heard of systems that crash because of so many users. That will be a similar case for messages. Too many incoming messages can put down a server. Spammers usually send an enormous amount of emails in an instant. With this throttling, senders will have to wait until they can send again. Legitimate users wait, while spammers give up. The SMTP proxy provides load balancing. In a small message system that receives few messages, one email server will be sufficient. But in today’s world, where billions of people interact using emails, one will not be enough. With the proxy, the system can have multiple mail servers, and each server can have a particular load assigned to them at a given time. The proxy’s job is basically to manage and assign the load to each server. The SMTP proxy also provides interoperability. This server works on any mail server. This means that you can change mail servers and still use the same proxy. An internet service provider may switch their incoming and outgoing mail servers, and leave the proxy untouched. The SMTP proxy is an invaluable tool in today’s world. It can help make mail servers efficient and robust by protecting them from different threats posed by spammers, email worms, and unauthorized email senders.

A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server, then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache. In some cases, the proxy may alter the client’s request or the server’s response for various purposes.

Web proxy servers are generally classified into four groups: Transparent, Anonymous, Distorting, and High Anonymity. Transparent proxies identify themselves as a proxy server and also makes the original IP address available through the http headers. Anonymous proxies identify themselves as a proxy server but does not disclose the original IP address. Distorting proxies identify themselves as a proxy server, but make an incorrect original IP address available through the http headers. High Anonymity proxies do not identify themselves are proxy servers and do not reveal the original IP address.

When it comes to security the bottom line is to be wary when using proxy servers, and only use proxy servers of known integrity (e.g., the owner is known and trusted, has a clear privacy policy, etc.), and never use proxy servers of unknown integrity. If there is no choice but to use unknown proxy servers, do not pass any private information (unless it is properly encrypted) through the proxy.

If you are in the habit of using proxy servers and are unsure of their type you can visit whatismyipaddress.com and try the proxy tester to see if your proxy server is detectable.
