This post is about remote login using SSH and fetures of SSH. It also describes the methode to copy files from a remote machine using scp

The Secure Shell (SSH) and Secure Copy (SCP) make remotely performing system administration and copying files across secure links a painless operation. SSH and SCP use the same SSH protocol to protect network communications, but they rely on users knowing if they want a shell or to copy a file beforehand.

In a previous article, I went over some of the basic functions of ssh. In that article, I mentioned that simple remote shell access was not the most interesting thing you can do with ssh. I pointed out that remote command execution was more interesting than mundane remote shell access.

Use Secure Shell (SSH) to run commands on remote UNIX® systems and, with some simple scripts, put together a system that enables you to manage many systems simultaneously from one machine without having to log in directly to the machines themselves. Also examine the basics of a distributed management system and some scripts and solutions using the technique.

KontrolPack provides a large list of network related features such as : remote shell command execution, file transfer, network overview, etc... The objective of this project is to improve system interoperability by connecting remote computers, regardless of their operating system, and remotely executing shell commands over the network.

Learn how to restrict remote execution of commands over ssh.

To use scp to transfer files, the SSH service (usually the sshd server daemon) must be running on the remote system. Here are some examples of useful scp commands:

sitecopy is a tool for copying locally stored web sites to a remote web server (using FTP or WebDAV). It helps you to keep the remote site synchronized with your local copy by uploading modified local files and deleting remote files that have been deleted on the local computer.
