This post includes SCP examples. SCP or secure copy allows secure transferring of files between a local host and a remote host or between two remote hosts. It uses the same authentication and security as the Secure Shell (SSH) protocol from which it is based. SCP is loved for it’s simplicity, security and pre-installed availability.

Introduction The scp command is used to copy files and directories between one computer to another. What is valuable about this utility is the fact that it used ssh to tunnel the copying. This means that the data is encrypted because it rides on ssh’s secure features.

The SCP protocol 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 utilizes 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, optionally including their basic attributes (permissions, timestamps). Clients can also request files or directories from a server (download). SCP runs over TCP port 22 by default. Like RCP, there is no RFC that defines the specifics of the protocol.

SCP is an awesome tool. Learn it, Love it, Use it….

The most common way to get terminal access to a remote Linux machine is to use Secure Shell (SSH). To work, the Linux server needs to be running a SSH server (OpenSSH) and at the other end you need a SSH client, something like PuTTy in Windows or the ssh command line tool on Linux or other Unix-like operating systems such as FreeBSD.

The attraction of SSH is that the connection between the two machines is encrypted. This means that you can access the server from anywhere in the world safe in the knowledge that the connection is secure. However the real power of SSH is that the secure connection it provides can be used for more than just terminal access. Among its uses is the ability to copy files to and from a remote server.
