The
Socks is a circuit-level gateway that Davidkoblas developed in the 1990. Since then, it has been used as an open standard in Internet RFCs. The socks runs on the TCP layer of the protocol stack. Unlike Winsock, SOCKS does not require applications to follow specific operating system platforms, such as Windows Winsock. Unlike the application-tier proxy and the HTTP-layer proxy, the Socks agent simply passes packets without concern for the application protocol (such as FTP, HTTP, and NNTP requests). So the SOCKS proxy server is much faster than the application tier proxy server. It is because of the SOCKS proxy server that we can connect to the Internet through it. (Sockscap is such a client software)
Common to have SOCKS4 and SOCKS5 two versions socks, where the SOCKS4 agent supports only TCP protocols, the SOCKS5 Agent supports TCP and UDP protocols, and various authentication mechanisms are supported, Server-side domain name resolution, and so on. SOCKS4 capable SOCKS5 can do, the reverse is not, such as ICQ can only use SOCKS5 agent, and FTP can use SOCKS4 and SOCKS5. SOCKSCAP32 is a tool developed by NEC to enable all Winsock applications to use SOCKS proxies. It adds a "hat" to the Winsock system call Library, and all Winsock calls that are generated in sockscap environments are intercepted by Sockcap, and when you set SOCKCAP32 correctly, Such invocation requests are automatically converted to requests to a specific socks agent, so that your original application that does not support socks agents can also be socks agents. SOCKCAP32 supports SOCKS4 and SOCKS5 proxies, the SOCKS4 proxy only supports TCP applications, while the SOCKS5 agent can support TCP and UDP, but because the SOCKS5 agent has a dedicated user identification operation, and the SOCKS4 agent does not, Therefore, generally open to the socks agent is SOCKS4 agent, so, UDP applications are often not supported, such as various network telephony software.
