PowerPoint Presentation: SOCKS proxy PowerPoint Presentation: A SOCKS proxy is usually located between a local network and the Internet channel. PowerPoint Presentation:  A proxy server is a computer that acts as an intermediary between your computer and the internet. Any traffic routed through a proxy server will appear to come from its IP address, not your computers. Unlike VPN servers, proxy servers do not have to devote resources to encrypting all traffic that passes through them, and therefore can accept simultaneous connections from a great many more users.  Proxy usually servers communicate with the internet using one of 2 different protocols; HTTP or SOCKS. PowerPoint Presentation: What is SOCKS proxy server and what is HTTP proxy server? PowerPoint Presentation: Actually SOCKS proxy and HTTP proxy severs, both behave in the same way. They are forwarding your requests to the destination host (address). With help of SOCKS or HTTP proxy servers you could bypass any firewall restriction and access any web site like: facebook.com, myspace.com, bebo.com, youtube.com and etc. PowerPoint Presentation: HTTP proxy server - The HTTP proxy server was originally designed to be used only with HTTP protocol. To say it even simpler, if you need to open any http:// or https:// like web address HTTP proxy servers are the best solution in 90% cases. There are almost no difference between SOCKS and HTTP proxy servers if they are used for HTTP protocol PowerPoint Presentation: SOCKS proxy servers - The SOCKS buy proxy servers are more flexible and do not seize you. While HTTP proxy servers could hide your IP only when you are browsing a web page, SOCKS proxy servers could help you keep your information private (your IP) even when you are using such programs like ICQ, Skype, MSN or even email clients like Outlook, TheBat, Thhunderbird. PowerPoint Presentation: Can HTTP proxy server used in the same way like SOCKS proxy server? PowerPoint Presentation: It is said here Bust the myth: SOCKS better than HTTP proxy server that if you will use CONNECT method of HTTP proxy server then HTTP proxy server could be used for any protocol, the same like SOCKS proxy server. That definition is right but with one exception: in 90% cases HTTP proxy server limits protocols for which CONNECT method could be used. Basically CONNECT method is allowed only for HTTP protocol over SSL or https:// like web addresses. That is because HTTP proxy server filter/updates client's each request. They need to change header information before they will forward it to the destination host (address), while SOCKS proxy servers work more like an open relay. SOCKS proxy server tunnels data directly to the destination host (address) as it comes from the client, without changing anything in the source. PowerPoint Presentation: So that is why SOCKS servers are so useful and cannot be replaced with simple HTTP proxy servers. Also there are other advantages of SOCKS proxy servers over HTTP proxy servers! If you are interested, please keep reading... also if you are software developer we will also provide you with self-coded implementation of SOCKS4 and SOCKS5 in PHP scripts. So later you can easily use not only regular HTTP proxy servers but also SOCKS4 and SOCKS5 in your scripts with anonymous proxy . If you need a hand how to implement usage of SOCKS4 and SOCKS5 into your scripts, don't hesitate to contact us. We are here to help you! PowerPoint Presentation: What are the differences between SOCKS4 and SOCKS5? PowerPoint Presentation: The number 4 and 5 refers to the version of SOCKS protocol. These two versions are the most popular and became wide spread all over the world. The following new features were implemented in 5th version: various authentication mechanisms, support of UDP protocol and IPv6. We do not think that you will ever use directly UDP protocol but there is a high chance that the program, for which you need to use proxy server, will use it. In that case nor HTTP private proxy neither SOCKS4 will work, the only solution to keep your IP hidden is to use SOCKS5. Another advantage of SOCSK5 is various authentication mechanisms. Without authentication your SOCKS proxy server is publicly available, even if you do not want it to be a public one. As soon as you will setup SOCKS4 proxy server, any person can use it without your permissions, he/she just needs to know IP and the port of SOCKS proxy server. PowerPoint Presentation: What are the advantages of SOCKS proxy server? PowerPoint Presentation: The main advantage of SOCKS4 and SOCKS5 proxy servers over HTTP proxy servers is that they use only secure connection between client and the private proxy server . That means nobody; including your internet provider or administrator of local area network cann’t see what you are actually sending or receiving. That is why SOCKS servers are so popular! They guarantee that your private information is secure and kept private. PowerPoint Presentation: As we already said, all SOCKS proxy servers work as open relay. That means there are no limitations for which protocols SOCKS proxy server will be used. Such no limitations allows us to use SOCKS proxy servers for creating ‘proxy chains’. If you ever heard term ‘proxy chain’ then SOCKS is that type of proxy servers which are used to create them. Here is the principle how it works, one proxy establishes connection to another one, that proxy in turn establishes connection to the next one and so on... so you could have several proxy servers chained: Source client » SOCKS1 » SOCKS2 » SOCKS3 » SOCKS4 » Destination host PowerPoint Presentation: As more SOCKS SSL private proxy servers are involved in proxy chain as higher the security and privacy level. Just imagine, if someone will somehow manage to get client’s IP by checking last SOCKS4’s log file (if such exist) it will points to the IP of SOCKS3 proxy servers instead of your IP ;) SOCKS3’s log file will point to the IP of SOCKS2 and so on... PowerPoint Presentation: Also SOCKS proxy servers could create reverse connections. In some cases your local administrator could block all outgoing connections for security reasons. At the same time incoming connections could be kept open. In that case instead of establishing connection from your PC to SOCKS proxy server, you can ask SOCKS proxy server to establish connection with your PC. After that, communication between client and SOCKS proxy server will remain the same as if use establishes connection by his/her own. PowerPoint Presentation: Thanking you!!!
