"SCP" commonly refers to both the Secure Copy Protocol and the program itself. It is based on the Secure Shell (SSH) protocol. 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. The IETF Internet Draft states that, even though this protocol is described in the context of the SSH-2 protocol, it could be used in a number of different applications, such as secure file transfer over Transport Layer Security (TLS) and transfer of management information in VPN applications It was designed by the Internet Engineering Task Force (IETF) as an extension of the Secure Shell protocol (SSH) version 2.0 to provide secure file transfer capabilities. SSH File Transfer Protocol (also Secure File Transfer Protocol, or SFTP) is a network protocol that provides file access, file transfer, and file management over any reliable data stream. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP).įTPS is an extension to the commonly used File Transfer Protocol that adds support for the Transport Layer Security and, formerly, the Secure Sockets Layer cryptographic protocols. FTP users may authenticate themselves with a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. It may also be beneficial to get assistance from someone that has technical experience with troubleshooting software or connectivity issues.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. You may also want to close/disable any other software or firewalls that are running to eliminate any possible conflicts with the FTP program. There are many available and are easy to use. If you are using Internet Explorer as an FTP program and having issues, it is recommended to download a standalone FTP client.
