Secure copy protocol (SCP) is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. [1] "SCP" commonly refers to both the Secure Copy Protocol and the program itself. [2]
Its main function is secure file transfer between a local computer and a remote server. [6] Beyond this, WinSCP offers basic file manager and file synchronization functionality. For secure transfers, it uses the Secure Shell protocol (SSH) and supports the SCP protocol in addition to SFTP. [7] Development of WinSCP started around March 2000 and ...
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).
For example, if the command rsync local-file user@remote-host:remote-file is run, rsync will use SSH to connect as user to remote-host. [14] Once connected, it will invoke the remote host's rsync and then the two programs will determine what parts of the local file need to be transferred so that the remote file matches the local one.
Compared to the SCP protocol, which only allows file transfers, the SFTP protocol allows for a range of operations on remote files which make it more like a remote file system protocol. An SFTP client's extra capabilities include resuming interrupted transfers, directory listings, and remote file removal. [2]
rcp can copy a file or directory from the local system to a remote system, from a remote system to the local system, or from one remote system to another. [16] The command line arguments of cp and rcp are similar, but in rcp remote files are prefixed with the name of the remote system:
The stub represents a remote object or service on a local system. It acts as a proxy for the remote service and allows the client program to make method calls on the remote object as if it were local. The process of generating stubs involves creating a client-side proxy object that provides the same interface as the remote service, but routes ...
Once defined, the remotes are referenced by other rclone commands interchangeably with the local drive. Remote names are followed by a colon to distinguish them from local drives. For example, a remote example_remote containing a folder, or pseudofolder, myfolder is referred to within a command as a path example_remote:/myfolder. [36]
