The Kermit protocol can operate over any computer-to-computer transport: direct serial, modem, or network (notably TCP/IP, including on connections secured by SSL, SSH, or Kerberos). OBject EXchange is a protocol for binary object wireless transfer via the Bluetooth standard. Bluetooth was conceived as a wireless replacement for RS-232.
Telnet consists of two components: (1) the protocol itself and (2) the service component. The telnet protocol is a client-server protocol, based on a reliable connection-oriented transport. [2] This protocol is used to establish a connection to Transmission Control Protocol (TCP) port number 23 or 2323, where a Telnet server application is ...
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.
They run Telnet or SSH on their client (PC) and attach to the terminal server, then connect to the serial device. In this application, terminal servers are also called console servers because they are used to connect to console ports which are found on products like routers, PBXes, switches and servers (Linux or Sun).
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
Socket: Data sent over a network interface, either to a different process on the same computer or to another computer on the network. 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
The first word, telnet, is the official name of the service. It is resolved using the system database to map port numbers and protocols to service names. In this case, /etc/services should contain: telnet 23/tcp The second and third words describe the type of socket and underlying protocol respectively. The /etc/protocols database is consulted
The TCP connection over which the TELNET protocol is layered provides a full-duplex connection, with no echo, across which data may be sent in either direction simultaneously. [11] Whereas the Network Virtual Terminal that the TELNET protocol itself incorporates is a half-duplex device with (by default) local echo.
