The Secure Shell, or SSH, provides a way of running command line and
|
|
graphical applications, and transferring files, over an encrypted
|
|
connection. SSH uses up to 2,048-bit encryption with a variety of
|
|
cryptographic schemes to make sure that if a cracker intercepts your
|
|
connection, all they can see is useless gibberish. It is both a
|
|
protocol and a suite of small command line applications which can be
|
|
used for various functions.

SSH replaces the old Telnet application, and can be used for secure
|
|
remote administration of machines across the Internet. However, it
|
|
has more features.

SSH increases the ease of running applications remotely by setting up
|
|
permissions automatically. If you can log into a machine, it allows you
|
|
to run a graphical application on it, unlike Telnet, which requires users
|
|
to type lots of geeky xhost and xauth commands. SSH also has inbuild
|
|
compression, which allows your graphic applications to run much faster
|
|
over the network.

SCP (Secure Copy) and SFTP (Secure FTP) allow transfer of files over the
|
|
remote link, either via SSH's own command line utilities or graphical tools
|
|
like Gnome's GFTP. Like Telnet, SSH is cross-platform. You can find SSH
|
|
servers and clients for Linux, Unix, all flavours of Windows, BeOS, PalmOS,
|
|
Java and Embedded OSes used in routers.

Encrypted remote shell sessions are available through SSH

|
(http://www.ssh.fi/sshprotocols2/index.html

|
|
allowing secure remote administration.
