v. t. e. The Secure Shell Protocol ( SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. [1] Its most notable applications are remote login and command-line execution. SSH was designed on Unix-like operating systems, as a replacement for Telnet and for unsecured remote Unix shell protocols ...
Secure Shell tunneling. A Secure Shell (SSH) tunnel consists of an encrypted tunnel created through an SSH protocol connection. Users may set up SSH tunnels to transfer unencrypted traffic over a network through an encrypted channel. It is a software-based approach to network security and the result is transparent encryption.
Secure Shell (SSH) OSI layer. Application layer (7) Port (s) 22/TCP. In computing, the SSH File Transfer Protocol (also known as Secure File Transfer Protocol or SFTP) is a network protocol that provides file access, file transfer, and file management over any reliable data stream. It was designed by the Internet Engineering Task Force (IETF ...
Secure Copy Protocol. The SCP is a network protocol, based on the BSD RCP protocol, which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and uses the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit. A client can send (upload ...
OpenSSH or OpenBSD Secure Shell. OpenSSH (also known as OpenBSD Secure Shell [a]) is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture. [4] [5]
The File Transfer Protocol ( FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. [1] FTP users may authenticate themselves with a plain ...
ssh-agent. Secure Shell (SSH) is a protocol allowing secure remote login to a computer on a network using public-key cryptography. SSH client programs (such as ssh from OpenSSH) typically run for the duration of a remote login session and are configured to look for the user's private key in a file in the user's home directory (e.g., .ssh/id_rsa ).
remote shell (rsh) The remote shell ( rsh) is a command-line computer program that can execute shell commands as another user, and on another computer across a computer network . The remote system to which rsh connects runs the rsh daemon (rshd). The daemon typically uses the well-known Transmission Control Protocol (TCP) port number 513.
