The SCP is a network protocol, based on the BSD RCP protocol, [5] 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) files to a server ...
At the outset of the IETF Secure Shell File Transfer project, the Secsh group stated that its objective of SSH File Transfer Protocol was to provide a secure file transfer functionality over any reliable data stream, and to be the standard file transfer protocol for use with the SSH-2 protocol.
The advantage of FISH is that all it requires on the server-side is an SSH or RSH implementation, Unix shell, and a set of standard Unix utilities (like ls, cat or dd—unlike other methods of remote access to files via a remote shell, scp for example, which requires scp on the server side).
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
The Secure Shell protocols are used in several file transfer mechanisms. Secure copy (SCP), which evolved from RCP protocol over SSH; rsync, intended to be more efficient than SCP. Generally runs over an SSH connection. SSH File Transfer Protocol (SFTP), a secure alternative to FTP (not to be confused with FTP over SSH or FTPS)
The client interacts with the remote file system via the SSH File Transfer Protocol (SFTP), [4] a network protocol providing file access, file transfer, and file management functionality over any reliable data stream that was designed as an extension of the Secure Shell protocol (SSH) version 2.0.
An ongoing transfer of file data over the data connection can be aborted using an interrupt message sent over the control connection. FTP needs two ports (one for sending and one for receiving) because it was originally designed to operate on top of Network Control Protocol (NCP), which was a simplex protocol that utilized two port addresses ...
The term secure file transfer protocol or secure FTP may refer to: Network protocols. SSH File Transfer Protocol — a file transfer protocol specifically developed by the IETF to run over secure shell connections; FTP over SSH, also known as "secure FTP" — the practice of using SSH to tunnel the older, well-known File Transfer Protocol (FTP)
