A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
Sockstress is a user-land TCP socket stress framework that can complete arbitrary numbers of open sockets without incurring the typical overhead of tracking state. Once the socket is established, it is capable of sending TCP attacks targeting specific types of kernel and system resources such as Counters, Timers, and Memory Pools.
A TCP connection is managed by an operating system through a resource that represents the local end-point for communications, the Internet socket. During the lifetime of a TCP connection, the local end-point undergoes a series of state changes: [ 31 ]
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.
The user-level solution is to avoid write–write–read sequences on sockets. Write–read–write–read is fine. Write–write–write is fine. But write–write–read is a killer. So, if you can, buffer up your little writes to TCP and send them all at once. Using the standard UNIX I/O package and flushing write before each read usually works.
listen() is used on the server side, and causes a bound TCP socket to enter listening state. connect() is used on the client side, and assigns a free local port number to a socket. In case of a TCP socket, it causes an attempt to establish a new TCP connection. accept() is used on the server side. It accepts a received incoming attempt to ...
tun2socks, an open source tool that creates virtual TCP TUN adapters from a SOCKS proxy, capable of UDP if supported on another end. Works on Linux and Windows, [ 22 ] has a macOS port and reimplementation in Golang . [ 23 ]
When data segments arrive in the wrong order, TCP buffers the out-of-order data until all data can be properly re-ordered and delivered to the application. Heavyweight – TCP requires three packets to set up a socket connection before any user data can be sent. TCP handles reliability and congestion control.
