What is Proxy Server & What is SOCKS Proxy Server

A proxy server is a server that retrieves Web pages for you, providing only its own identity to the sites it visits. Requesting data comes first to the proxy, and through the requested proxy, the data is transmitted to you.

Anonymous proxy server hide your IP address and hide information about you and your interests. Besides that, anonymous proxy server can help in the cases when, for example, the owners of the Internet resource force some limitation on users from certain countries, cities, geographic regions or even restrictions on some IP address ranges.

SOCKS is a protocol for handling traffic through a proxy server. It can be used with virtually any TCP/UDP application, including Web browsers and FTP clients. It provides a simple firewall because it checks incoming and outgoing packets and hides the IP addresses of client applications. Using Socks proxy is a good solution for internet anonymity and security.

There are two types of Socks proxy protocols: Socks 4 and Socks 5. Socks 4 proxy will allow working with TCP protocols only, like HTTP (web browsing via IE, Opera, Firefox, Safari), NNTP newsgroup access, IRC. Socks 5 proxy is more advanced, allowing to anonymize UDP protocols as well (ICQ for example) Many popular applications support SOCKS proxies: Firefox, Google Chrome, Thunderbird, Safari.

SOCKS proxies can be tunneled easily with a tool such as Proxychains(Linux) and Proxifier(Windows).

What is new in this release:

• This release was upgraded with the NiX Proxy Checker PRO engine, which contains various internal fixes, optimizations, and bug fixes.
• The new included SG loaders fix segfaults when using PHP 5.3.x.
• Built-in, up-to-date proxy country detection was added.
• This is the last update to the free version, which is now considered stable.

What is new in version 1.5.1:

• The "Client cannot resolve the hostname" SOCKS5 feature was reverted, because a majority of public SOCKS5 proxies are unreliable.
• The program should now give significantly more proxies.
• Hostnames are now only resolved once.
• Transparent proxy support has been added.

What is new in version 1.5.0:

• Fixed occasionally occurring timeout issue on HTTP proxy checks.
• The program should now give more HTTP proxies.

What is new in version 1.4.3:

• Threading was improved, so the program should be less CPU intensive. A bug was fixed, so at the end of a check, "Waiting for the running threads" now works as intended. As a new feature, proxies are now formatted to suitable format for the upcoming tool called NiX - Brute Force

What is new in version 1.4.2:

• A bug fix: Previous versions of NiX did not give any HTTP proxies results if the user used AZ Environment variables as Proxy Judge. This issue has now been fixed.

What is new in version 1.4.1:

• Bug fixes:
• - This release respects the following settings whether those are set or not: Bad_Dns, Bad_Ip and Bad_Port
• - If a user edited proxychk.conf with windows editor; Convert the file back to Unix format automatically
• A user requested feature:
• - Epoch timestamp will be added to proxies.txt for "checked ago" purposes. Needless to say, this will require a script that parses proxies.txt and either adds the results to the database or generates HTML page with the provided info.

What is new in version 1.4.0:

• Added features:
• Estimated Time Remaining feature added so you can see how much time is left on your current check
• Proxy List results are formatted to both simple and detailed outputs
• Configurable option will allow NiX to autocheck for updates upon starting
• Bug fixes:
• Proxy delay information has been fixed.
• Respects now "RDelay" setting
• A timeout issue has been fixed in protocol auto-detection logic
• Freeware version limitation: Threads are locked to 12

What is new in version 1.3.3:

• A bug fix: There was a flaw in an array subsitution that caused non-existent pids in an array that keeps track of forked child processess. A hung task routine might have killed wrong processes. I am really sorry and apologize for the inconvenience this may have caused.
• Due to the above fix:
• NiX can now be ran as root, previous versions did not allow this
• There should also be about 10% speed improvance compared to earlier versions while using the same amount of threads.
• A bug fix: Respects now GeoIP and Debug settings
• Freeware version limitations: Threads are locked to 12 and only 1024 proxies.

What is new in version 1.3.2:

• Now both Socks 4/5 proxies get checked against defined site (Proxy Judge)
• Fake proxy detection has been improved
