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 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.
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 ...
TCP/IP stack fingerprinting is the remote detection of the characteristics of a TCP/IP stack implementation. The combination of parameters may then be used to infer the remote machine's operating system (aka, OS fingerprinting ), or incorporated into a device fingerprint .
The ØMQ message queueing library provides so-called sockets (a kind of generalization over the traditional IP and Unix sockets) which require indicating a messaging pattern to be used, and are optimized for each pattern. The basic ØMQ patterns are: [4] Request–reply connects a set of clients to a set of services.
Stream-oriented (TCP; data written through a socket requires formatting to preserve message boundaries) or more rarely message-oriented (UDP, SCTP). Most operating systems Unix domain socket: Similar to an internet socket, but all communication occurs within the kernel. Domain sockets use the file system as their address space.
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
Parallel connections also have congestion control operating independently of each other, rather than being able to pool information together and respond more promptly to observed network conditions; [108] TCP's aggressive initial sending patterns can cause congestion if multiple parallel connections are opened; and the per-connection fairness ...
