Proxy Services

Free proxy surfing- essential in our days

Today more and more people use the Internet, because all we need to know is just a click away. The Internet is a very efficient and quick way of finding information about almost everything. However, there is also a bad side to the Internet and that is that you are exposed to hackers and your every step on the net can be monitored.

Because privacy, Internet crime, hacking were becoming more and more of an issue and many people were afraid to use the Internet because of the consequences, free proxy surfing sounded like a dream, something that had to be done. If software was designed to insure the privacy, the anonymity of the people using the Internet, then all of these problems would find their ending. With free proxy surfing, people did not have to worry anymore about somebody spying their every move or finding out their address or even their social security numbers.

Free proxy surfing is like a buffer between you and the web sites that you want to visit. It allows you to view as many information as you want on the Internet without the concern of being tracked. There are two ways that this can be accomplished: by using a program that can insure your anonymity or by using free proxy sites.

Free proxy surfing with the help of programs is a little more complicated and may not always work. On the other hand free proxy sites are very easy to use and can guarantee a very good result. Nowadays more and more people are using free proxy sites to surf the net. All one has to do in this cases is visit the free proxy site that assures your anonymity and enter the web site address, URL, of the page that you want to visit and remain anonymous at the same time.

How does this work? Well, when using a free proxy site to surf the net and remain anonymous at the same time, the proxy retrieves all the web sites before they are actually delivered to the person. This way, the other server will not see your IP address or other information, but it will see the anonymous proxy’ s adress.

However, there are also some bad news when talking about free proxy surfing. Although, using free proxy sites sounds like a dream, there are also some downs that you should know about. When free proxy surfing, your browsing speed will slow down a little bit. Another thing is that there are many ads on these free proxy sites, that may drive you a little crazy at times. Moreover, there is always the chance that the actual proxy server record your data and a malicious server can find out everything about your machine. This can be avoided if using a free proxy server that is highly rated and also has a very specific privacy policy.

Enhance Employee Productivity with a Dual-Core Proxy Server

Sharing a single Internet connection among multiple users has never been simpler and UserGate also lets untrained people (not System Administrators) limit the Internet connectivity of their employees.

With a single external Internet connection and multiple users you simply decide on your priorities. If you are managing an office or a corporate network, security and employee productivity take precedence.

One factor that is not commonly recognized is that unlimited Internet connectivity can harm employee performance. When it comes to business networks ‘fast’ and ‘unlimited’ do not optimize productivity. The Internet is rife with spyware and viruses that can significantly threaten your corporate security and productivity. It only takes one virus getting through your security defenses to corrupt or even destroy the information on all of your networked computers, costing you days and weeks of recovery time. Spyware routinely steals sensitive information such as passwords and private documents. Spyware dramatically decreases computer performance and it displays annoying pop-up windows that distract and have to be closed off. Viruses and spyware have effectively paralyzed even the most technologically sophisticated corporations and you can now benefit from what they learned with the safeguards built into UserGate.

Expensive productivity threats are not always as covert as viruses or spyware. The Internet holds many distractions to your employees’ attention. It has become common for employees to use their office computers and their work time to play online Flash games aptly called ‘office killers’. Online chats and instant messengers are a close second to computer games in wasting employee time. If you pay for Internet traffic, an employee using your Internet connection to download music, games or even movies will cost you directly. If your organization uses VoIP to save on long distance bills, it is vital that no employee can use your Internet connection’s entire bandwidth. Otherwise your calls will not go through, and you can easily lose a client because of a missed call or because the conversation quality is embarrassingly poor.

Even though these various threats are real and are severe, some very highly trained engineers put together a simple solution that minimizes them and increases your employee productivity. UserGate proxy server produced by Entensys (http://www.entensys.com/) provides Internet connectivity to your entire organization while eliminating the usual threats and performance bottlenecks caused by Internet Connection Sharing. UserGate blocks viruses and spyware with its advanced dual-core anti-virus*. UserGate limits your employees to their work assignments instead of socializing over the Internet or wasting time, and it saves on your Internet bills by monitoring, limiting and optimizing the bandwidth used by each employee.

*Dual-core anti-virus is very real and very powerful. When Intel released its first dual-core processor, the benefits of increased performance and smoother multitasking became obvious to even the most conservative users. With two anti-virus cores-Panda and Kaspersky-and real-time online updates, UserGate provides tighter security and higher reliability than any single anti-virus solution. Being a proxy server, UserGate prevents spyware and viruses from getting onto your employee computers by scanning all external Internet traffic.

Once installed, UserGate becomes the only connection between your employees and the Internet. Workers cannot access anything beyond your corporate network and external influences cannot affect your computers. This approach allows for extremely effective control over how and when your employees can use your Internet connections. You can prohibit access to specific file types, sites, resources or protocols making it impossible for employees to chat, download personal-use files or play online games during their work time. VoIP connections can be prioritized over end-user traffic, allowing for crystal clear phone calls over the Internet. Additionally, thanks to extensive journal support, you will always be able to see exactly what has been accessed by each employee and the bandwidths they consumed.

VegaStream - VoIP Security

These security concerns are being addressed by service providers and equipment manufacturers to make VoIP calls secure and to give buyers peace of mind. Furthermore, as the broader issue of security on and over the Internet is being addressed by the industry, global standards bodies and governments, so we can expect positive impact in the issue of secure VoIP. Meanwhile, and even after these security enhancements become commonplace, businesses must take steps to secure their VoIP network, as they should secure any point of access to the business, its intellectual property and its data……

Simple Steps For Network Security

VoIP networks are vulnerable to exactly the same security risks as traditional IP data networks and VoIP security needs to be at the same level. This is a relatively straightforward exercise for businesses that already operate secure IP networks.

Protecting VoIP Systems

Organizations should adopt a multi layer comprehensive security strategy. The network can be segmented into secure zones protected by a firewall, intrusion prevention should be added, as well as other layers of security. Although there is no such thing as totally secure IP network, a company can secure the voice network by putting in place layers of security to protect telephones, conversations, computers, and servers. A competent IT department, together with support from the VoIP service provider or solution reseller should be able to implement Authentication, control access (passwords and firewalls), encryption, an audit trail of calls and, where necessary, recording those calls.

Don’t forget internal Security

Protection should of course also be put in place for internal traffic flowing over a VoIP system. An increasing number of workers use VoIP to communicate with company staff from wireless phones or soft phones. It is a sensible precaution to encrypt VoIP traffic moving internally over a corporate network to prevent attacks from insiders. The use of desktop-based soft phones to make and receive VoIP-based telephone calls can create a hole in firewall security. The best way to address this problem is to restrict access to the network. In addition, all inbound VoIP traffic that flows through a firewall should be routed through a proxy server, thus eliminating a direct connection to the Internet. Again, these are relatively simple and low cost steps to secure the network.

Peace of Mind With VoIP System

Many corporate users are discouraged from using VoIP systems as they feel they are not secure however, this is like saying it is not safe to use a computer on the internet. Securing VoIP systems is like securing any IP network. Just as you would look to set up protection on your PC including virus software, firewalls etc, so to do you need to protect a VoIP system in a similar fashion. VoIP can and is secure, providing certain security steps are taken. Security is not a server issue, it is a network issue.

5 Tips To Increase PPC Earnings

The following are my top 5 tips on how to increase your google adsense earnings. These methods are not guaranteed to work, but if followed correctly they will give you a great starting point. Also the effectiveness of these tips depends on the type of site being run, they will be more effective on a movie review site then a proxy or flash arcade site. So let’s get started.

5) Revenue Sharing Forums.

This is not a very effective way of increasing earnings, but every penny helps at this stage of the game. So check the forums that you frequent, view the user options and if available add your google adsense user i.d. Now when you post in these forums and an ad is clicked you will receive a portion of the profits.

4) Create Channels.

Make sure you create unique channels for each set of ads, this way you know which ad groups perform best and which ad groups you need to alter. The most effective way to use channels is to have a single channel created for each ad space. If you have ads beneath your header, name the channel header, it’s that simple. From this point on page views, clicks etc will be viewed under this channel.

3) Blending your Ads.

This may be the most important part of increasing your earnings. The optimal look on your site is to have the adsense links blend with your site links and the adsense description blend with the content on your site. You may also want to blend the background and border with the background on your page. Black ads on a white site are just begging for a 0.00% ctr.

2) Choose the Correct Ad Sizes.

This step is quite obvious but for the sake of the article and new adsense users I will indulge anyhow. You DO NOT want to bombard your users with massive ads, adsense or not. For the most part larger ads do work better, as long as they fit well into the layout of your site.

1) Choose the Correct Placement for Your Ads.

This completely depends on the type of site that you run. The majority of the time you will be adding your Google Adsense Ads above the fold (the bottom of the screen when opening a new page), and inside the content or menu. This will ensure your ads will be viewed while your content is being read or site being navigated.

Now while doing this you want to avoid making it look like you are trying to trick the user into clicking on your ads, if you do try to trick them it may result in one of two things. One, your users may feel deceived and not revisit your site, thus diminishing any opportunity of clicks next time. Two, you may violate google adsense terms of service and be banned from adsense for good.

The best of luck to everyone.

Anti-Spam Filters: How to Find the Right Software for Your System

Some people actually like spicy meat in a can. But nobody likes email spam. That’s why anti-spam filters are a good thing. Most email programs come with built-in filters. Add-on filters are also available that function as email proxies. The spam filter lives on your computer like a local email server, acting as a proxy between your ISP’s mail server and your email client, such as Eudora or Outlook. Once it’s installed, the add-on filter checks your mail, filters out all the spam it can identify, and then sorts or deletes it according to your preferences.

Spam Filters for Windows Users

Add-on spam filters, like other software, are designed to operate with specific configurations. Windows users will find the widest selection and easiest access to programs. You can search and download a program that’s compatible with any version of Windows on the vendor’s websites.

For users with POP3 or IMAP accounts or folks who use other email services such as AOL, Yahoo!, or Hotmail, an add-on spam program for Windows might still work. Many of these accounts can be filtered via your Outlook or Outlook Express applications and are therefore compatible with Windows software.

In fact, some of the newer filters offer plug-ins that filter messages on your handheld email device. Anti-spam on the go!

Spam Filters for Mac and Other Users

A quick web search should result in several anti-spam options for Mac users. Most are compatible with Mail or Eudora email clients. Some Mac-friendly filters are even capable of filtering mail in POP3, IMAP, and Exchange accounts.

For users employing other operating systems, such as a Linux box, add-on anti-spam options do exist. Try searching the Mac compatible programs to find versatile software.

Spam Filters for the Computer Challenged

If downloading software and following an endless series of setup box instructions isn’t your favorite way to spend the afternoon, fear not. Spam filters maintained at an offsite server could work for you.

If you have very little memory left on your hard drive or you just don’t like configuring software, try one of the subscription services available online. For a small monthly fee, your messages will be routed through their filters before arriving in your inbox relatively spam-free.

A Life Without Spam

Most users find that adding on an anti-spam program is well worth the small cost and minimal time investment. To choose the right software for your computer, be sure you know your system requirements and make a list of the features that are important to you. You could be headed for a spam-free future.

SIP Server

The design is such that SIP clients use TCP and UDP port 5060 to connect the SIP servers and others SIP endpoints. The sole purpose of SIP uses are setting up and tearing down voice or video calls. Where session initiation is required, however, SIP is used as well. These include Event Subscription and Notification, Terminal mobility and so on. A lot of SIP-related RFCs actually define behaviour for such solutions. All voice/video communications are done over separate session protocols, like RTP.

SIP was tasked to provide a signaling and call setup protocol for IP-based communications that can support a superset of the call processing functions and features present in the Public Switched Telephone Network (PSTN). The SIP Protocol by itself, defines the focus of the call-setup and signaling. However, it has been designed to enable the building of these featured network elements called Proxy Servers and User Agents. As such, these are features that permit familiar telephone-like operations: dialing, ringing, hearing ring tones or busy signals. The implementation might be different but the behaviour is similar.

SIP enabled telephony networks can also implement many of the more advanced call processing features present in SS7 (Signaling System 7), though the two protocols themselves are different. SIP is a peer-to-peer protocol, characterized by highly complex central network architecture and dumb endpoints; therefore it requires only a very simple core network with intelligence distributed to the network edge, embedded. The features of SIP are implemented as compared to traditional SS7 features, which are implemented in the network.

SIP is characterized by its proponents as having roots in the IP community rather than the telecom industry although many other VoIP signaling protocols exist. While the H. 323 VoIP protocol has been traditionally more associated with the ITU, SIP has been standardized and governed primarily by the IETF. The two organizations have endorsed both protocols in some fashion.

SIP is like HTTP and shares some of its design principles as well. Things like readable by humans and request-response structured. Codes like ‘404 not found’ are used as well. SIP is much simpler than H. 323. However, some would counter that while SIP has a goal for simplicity, its current state is as complex as H. 323. It is a stateless control, that some might point out, hence making it possible to fail like other difficult protocols as well. SIP and H. 323 are not limited to voice communication but can mediate any kind of communication session from voice to video, maybe even unrealized applications in future.

Secured Web Conferencing - The Cost Effective Way

In due course, web conferencing has proved its worth over traditional audio or video conferencing. In those situations, where the basic meeting format is that of back and forth information flows, web conferencing is just second to face to face meeting.

However, security has always been a major concern with web conferencing. Mere SSL or AES encryption protocol cannot guarantee you complete access security though they are well known as industry standards. Corporate houses cannot ignore this viable communication media and at the same time cannot entirely depend on it for this very reason.

There are so many other problems in traditional web conferencing. The attendees who needed to deal with 3D CAD design, flash graphic design, and other similar collaborations of image based applications, had to fight hard to make the meeting effective up to the minimum level.

Another big problem with traditional web conferencing had been that the attendees had to download and install meeting client software. That is not all. The attendees needed to download Java, flash installations and others to support the client software. The whole process was tedious, time consuming and expensive (in some cases you need to pay monthly usage charges for your meeting client software).

Even after ignoring all these problems, you can not be sure that your meeting is held in a 100% secured atmosphere.

What next?

Here comes “on premise web conferencing appliances”, a secured and easy to use conferencing tool for corporate communication. Just install the appliance and you are ready to start the conference - round the clock.

With these appliances you do not need to pay any monthly fee or you do not need constant IT support. To add to this there is no way that a firewall, proxy server or anti virus can block it. And thus you get a hustle free and smooth conference.

This appliance is supported by all the platforms like Mac, UNIX, Linux or Windows. To add to this, you can attend the conference using your iPhone too - thus you can stay connected even while you are on the move.

The best thing about “on premise web conferencing appliances” is that you can use your firewall to protect access security of web conferencing attendees. Alongside, with some of these appliances, you get the facility to Remotely Access your computer.

To sum up, “on premise web conferencing appliance for web meeting” provides you a simple, easy to use, cost effective and secured conferencing tool for internal and external meetings.

Advantages Of Cheap Virtual Dedicated Server

Most webmasters started off using single domain hosting or shared web-hosting services. Shared web hosting means you share a server with dozens of other webmasters. Typically, shared web hosting plans allows you to have more than 1 domain per shared web hosting account with a predetermined hard disk space and bandwidth. The cost is usually pretty low. You only need to pay around 3-10 dollars per month.

Although it is cheap to host your website on single or shared web hosting accounts, there are many disadvantages you should be aware of.

By the nature of shared hosting, the server resources are shared among many websites, therefore it is very easy for resources such as CPU and memory to be used up quickly. Certain types of websites such as proxy sites are known to generate high CPU utilization, therefore if your website is on the same server, be advised there is a possibility of your website going down. Spam complaints against other sites on the same server will also affect your website. Any form of denial of service attack against someone else hosting can impact on the uptime of your website.

Also some web hosting companies over packed too many hosting accounts on one server causing the server to be slow and sluggish. The end result is your website is up but takes too long to load and display properly.

How can you do to avoid this issue?

Years ago, the only solution is to get a dedicated server. However, nowadays you can get a cheap virtual dedicated server for less than 30 dollars a month.

A cheap dedicated virtual server or VPS allows you to run your sites as if you own the server virtually. In reality, the dedicated server is spilt into multiple virtual dedicated servers. The main advantage is that each virtual dedicated server has control over it’s own resources such as CPU, RAM etc. So each virtual dedicated server is totally isolated from other virtual servers and will not be affected if other webmasters bring their servers down.

Some web-hosting providers also have unmetered bandwidth, which is a plus.

So Are There Any Disadvantages in having a virtual dedicated server?

There are not many major disadvantages except for cost. It will cost a little bit more on hosting. The other disadvantage is you need to be technically proficient in administering the server. However, some web-hosting providers also can provide managed virtual dedicated server. It means they will help you to manage the server. Examples are routine server maintenance, security patches etc.

With increased speed and reliability from using cheap virtual dedicated server, you will rest easy that your websites are always up while you are sleeping.

Network Security - Methods For Controlling Threats

Since firewalls are so commonly used it is worth exploring them in greater depth. Corporations often set up rules for managing their Web connections using firewalls. A firewall enables a company to designate how all end users can use their network and decide what information is passed through Web servers and other servers.

There are several methods a firewall uses to control traffic that comes into and goes out of the network. One way firewalls do this is through packet filtering. During this process a firewall analyzes small packets of information against pre-designated filters. All data is sent via small packets of information through filters. Safe information is passed through and unsafe information is generally removed.

Another way firewalls mitigate traffic is through proxy service. This means the firewall retrieved information from the Web and sends it to the requesting computer. Still another method of traffic control used by firewall is stateful inspection. This technique allows the firewall to compare certain parts of the data packet to information gathered from trusted sources. Information going to the firewall from the Internet is monitored to determine whether it contains key characteristics that suggest the information is safe rather than harmful. Information designated as safe passes through freely and other information is blocked.

The methods a company selects will depend on a number of factors including personal preferences. Regardless of the method a firewall uses however a company or network administrator can customize the firewall to filter information based on a pre-established set of criteria.

Internet Connection Sharing Made Simple

Connect Your Entire LAN to the Internet with a Single IP Address Simply and Securely.

If you want to connect a local area network (LAN) in your office to the Internet today, you have a number of options to choose from. The simplest is to buy a small stand-alone router or gateway. These devices are inexpensive, reliable and mostly plug-and-play. If you know what you’re doing, you can configure a router and network in less than an hour. However, this might not be your best choice.

There are significant reasons why a router is not the best solution. How secure does your data need to be? Do you need (or would like) to know exactly how much Internet traffic each of your PCs consumes? Do you have priority traffic that must get through? Do you have employees that might be using the Internet for purposes other than work?

A simple hardware gateway will not satisfy these conditions. You could invest a small fortune for a sophisticated device that would satisfy some of these and still not have the optimum solution.

An alternative to expensive hardware is setting up a dedicated computer to control Internet access and connectivity. In this case, your choice is economically limited to one of two platforms: *nix or Windows. While *nix (Unix, Linux, FreeBSD, etc) is technically terrific for the task, it is not as cost effective in a typical company with a multitude of Windows PCs. A *nix system bears a very important drawback: you will either have to hire a system administrator to manage it, or be unable to fine-tune Internet access and constantly risk network failure.

Using a dedicated Windows PC to control how your LAN users access the Internet is the only remaining choice. While Windows itself provides a limited set of basic connectivity features, you will need to purchase and set up dedicated gateway server software to use advanced features. UserGate 4.1 by Entensys is a proxy server for Windows that is not only the simplest gateway server to configure and use, but also has all the advanced features your company may require.

There are two ways UserGate can share an Internet connection among your LAN users. One way is to configure it as a gateway, very similar to stand-alone hardware routers. UserGate supports NAT and port mapping in order to share a single IP address between multiple LAN users. Using NAT requires no additional configuration on client computers, and is the fastest way to set up Internet access.

If you want more advanced features such as caching your Internet connections, you can set up a User Gate Proxy Server. The proxy server automatically caches the web resources your LAN users access most often, saving significant Internet bandwidth and seriously increasing access speeds. There is no way for your LAN users to bypass UserGate to access the Internet, so you can create powerful rules to control user access to certain resources or protocols.

You can also set up content filtering to block unwanted Web sites, resources, or specific file extensions (such as MP3 music).

Your LAN is always protected from external attacks by UserGate’s built-in firewall. The built-in anti-virus quickly scans all Internet traffic to protect your network from spyware, viruses and malicious software.

If you have different kinds of traffic, such as VoIP, you can easily limit the maximum bandwidth for every user in order to ensure that time-sensitive clients get the necessary bandwidth. You can also limit the connection speed for any network user and can control the maximum load of your Internet connection.

UserGate keeps complete statistics on every LAN user, including the list of visited URLs and their online time.

Its built-in billing makes UserGate a perfect solution for splitting a single Internet connection between several users.

The latest version adds VPN support, providing the same connection sharing and statistics features for private and public networks. Support of VPN and transparent proxy makes UserGate a perfect solution for safe and secure Internet connection sharing.
