    [threat] Remote Authentication Dial In User Service (RADIUS) RADIUS, or Remote Authentication Dial-In User service, is a freely available distributed security system developed by Lucent Technologies InterNetworking Systems. Lucent has worked with the Internet Engineering Task Force (IETF) to define RADIUS as an interoperable method for distributed security on the Internet. RADIUS was designed based on a previous recommendation from the IETF's Network Access Server Working Requirements Group.

  • threat
    [threat] Remote Authentication Dial In User Service (RADIUS) RADIUS accounting consists of an accounting server and accounting clients (Lucent (formerly Livingston Enterprises)PortMaster products). RADIUS accounting starts automatically when the RADIUS server starts. On a UNIX host, the radiusd accounting daemon is a child process of the radiusd authentication daemon. The RADIUS accounting server uses the User Datagram Protocol (UDP), and listens for UDP packets at port 1646 by default.

About TCP/UDP ports

TCP port 1141 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user's data can be sent bi-directionally over the connection.
Attention! TCP guarantees delivery of data packets on port 1141 in the same order in which they were sent. Guaranteed communication over TCP port 1141 is the main difference between TCP and UDP. UDP port 1141 would not have guaranteed communication as TCP.
UDP on port 1141 provides an unreliable service and datagrams may arrive duplicated, out of order, or missing without notice. UDP on port 1141 thinks that error checking and correction is not necessary or performed in the application, avoiding the overhead of such processing at the network interface level.
UDP (User Datagram Protocol) is a minimal message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768).
Application examples that often use UDP: voice over IP (VoIP), streaming media and real-time multiplayer games. Many web applications use UDP, e.g. the Domain Name System (DNS), the Routing Information Protocol (RIP), the Dynamic Host Configuration Protocol (DHCP), the Simple Network Management Protocol (SNMP).
TCP vs UDP - TCP: reliable, ordered, heavyweight, streaming; UDP - unreliable, not ordered, lightweight, datagrams.
