Questions tagged [raw-sockets]

An internet socket that allows direct sending and receiving of raw network packets that contain all headers. They differ from protocols like TCP/IP or UDP.

Raw sockets differ from standard sockets where the payload is encapsulated according to the transport layer protocol (TCP, UDP, HTTP, ..). Raw sockets can be used to implement completely new transport-layer protocols or to send messages through some less common protocol like ICMP.

Most socket APIs, especially those based on Berkeley sockets, support raw sockets. Support under Windows XP is intentionally limited due security concerns.
