This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
Python currently boasts a wide variety of web application frameworks, such as Zope, Quixote, Webware, SkunkWeb, PSO, and Twisted Web -- to name just a few. This wide variety of choices can be a problem for new Python users, because generally speaking, their choice of web framework will limit their choice of usable web servers, and vice versa...
A port scanner is an application designed to probe a server or host for open ports.Such an application may be used by administrators to verify security policies of their networks and by attackers to identify network services running on a host and exploit vulnerabilities.
Each of these applications (web server, email server, FTP server) is called a network service. In this system, network services are identified using two components: a host address and a port number. There are 65536 distinct and usable port numbers per host. Most services use a limited range of numbers by default, and the default port number for ...
The Gunicorn "Green Unicorn" (pronounced jee-unicorn or gun-i-corn) [2] is a Python Web Server Gateway Interface (WSGI) HTTP server. It is a pre-fork worker model, ported from Ruby's Unicorn project. The Gunicorn server is broadly compatible with a number of web frameworks, simply implemented, light on server resources and fairly fast. [3]
The Network Information Service, or NIS (originally called Yellow Pages or YP), is a client–server directory service protocol for distributing system configuration data such as user and host names between computers on a computer network. Sun Microsystems developed the NIS; the technology is licensed to virtually all other Unix vendors.
This allows using Twisted as the network layer in graphical user interface (GUI) programs, using all of its libraries without adding a thread-per-socket overhead, as using Python's native library would. A full-fledged web server can be integrated in-process with a GUI program using this model, for example.
The following is a list of web service protocols. BEEP - Blocks Extensible Exchange Protocol; CTS - Canonical Text Services Protocol; E-Business XML; Hessian; Internet Open Trading Protocol; JSON-RPC; JSON-WSP; SOAP - outgrowth of XML-RPC, originally an acronym for Simple Object Access Protocol; Universal Description, Discovery, and Integration ...
