Some system administrators choose to change this port, mainly for security reasons. SCP port runs over TCP port 22 by default, which is also the same default port for SSH. SCP can also be used when a file transfers from one host to another. In this sense, a file can be transferred from one remote directory to another directory that is on the same server. SCP can also be used remotely if a remote host is specified as both the source and the destination. In the case of Windows, it could be helpful to install a transfer application such as PuTTy. It can be found by typing the “scp” command on the computer.
SCP is a native command in most operating systems, such as macOS, Windows, or Linux. The SCP client can upload files to the SSH server or request the download of files and directories for downloading.

How to use Secure Copy Protocol (SCP) to transfer files Now, we are going to get technical, but the process it’s pretty straightforward. In contrast, SCP runs on an SSH network, which makes it more secure but is limited to a single closed network and works for a single file transfer at a time. FTP establishes a dual-port connection, which allows it to be fast and convenient but lacks security. In other words, SCP servers help you transfer files to and from servers, computers, and other networking devices using a secure SSH tunnel.įile Transfer Protocol (FTP) and SCP protocol are both file transfer protocols but have some differences.
It is based on the Secure Shell (SSH) protocol.
In short, the Secure Copy Protocol (SCP) is a method for securely transferring computer files between a local host and a remote host, or between two remote hosts. The SCP port has proven to be a very useful tool for SysAdmins.
