In computer networking, xinetd (Extended Internet Service Daemon) is an open-source super-server daemon which runs on many Unix-like systems, and manages Internet-based connectivity. [ 3 ] It offers a more secure alternative to the older inetd ("the Internet daemon"), which most modern Linux distributions have deprecated.
NetBIOS over TCP/IP (NBT, or sometimes NetBT) is a networking protocol that allows legacy computer applications relying on the NetBIOS API to be used on modern TCP/IP networks. NetBIOS was developed in the early 1980s, targeting very small networks (about a dozen computers).
Because both TCP and UDP run over the same network, in the mid-2000s a few businesses found that an increase in UDP traffic from these real-time applications slightly hindered the performance of applications using TCP such as point of sale, accounting, and database systems (when TCP detects packet loss, it will throttle back its data rate usage).
There are Linux-compatible NBD implementations for FreeBSD and other operating systems. The term 'network block device' is sometimes also used generically. Technically, a network block device is realized by three components: the server part, the client part, and the network between them.
Operating systems of the 1980s (DOS and Novell Netware primarily) ran NetBIOS over IEEE 802.2 and IPX/SPX using the NetBIOS Frames (NBF) and NetBIOS over IPX/SPX (NBX) protocols, respectively. In modern networks, NetBIOS normally runs over TCP/IP via the NetBIOS over TCP/IP (NBT) protocol. NetBIOS is also used for identifying system names in ...
Such short-lived ports are allocated automatically within a predefined range of port numbers by the IP stack software of a computer operating system. The Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Stream Control Transmission Protocol (SCTP) typically use an ephemeral port for the client -end of a client ...
Some operating systems, such as Linux and HP-UX, [citation needed] implement a half-duplex close sequence. If the host actively closes a connection, while still having unread incoming data available, the host sends the signal RST (losing any received data) instead of FIN.
netcat (often abbreviated to nc) is a computer networking utility for reading from and writing to network connections using TCP or UDP.The command is designed to be a dependable back-end that can be used directly or easily driven by other programs and scripts.
