PuTTY

PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator.SSH, Telnet and Rlogin are three ways of doing the same thing: logging in to a multi-user computer from another computer, over a network. Multi-user operating systems, such as Unix and VMS, usually present a command-line interface to the user, much like the `Command Prompt or `MS-DOS Prompt in Windows. The system prints a prompt, and you type commands which the system will obey.
Using this type of interface, there is no need for you to be sitting at the same machine you are typing commands to. The commands, and responses, can be sent over a network, so you can sit at one computer and give commands to another one, or even to more than one.

After you log in to the server, what happens next is up to the server! Most servers will print some sort of login message and then present a prompt, at which you can type commands which the server will carry out. Some servers will offer you on-line help; others might not. If you are in doubt about what to do next, consult your system administrator.

When you have finished your session, you should log out by typing the servers own logout command. This might vary between servers; if in doubt, try `logout or `exit, or consult a manual or your system administrator. When the server processes your logout command, the PuTTY window should close itself automatically.

This software contains following tools:
>PuTTY (the Telnet and SSH client itself)
>PSCP (an SCP client, i.e. command-line secure file copy)
>PSFTP (an SFTP client, i.e. general file transfer sessions much like FTP)
>PuTTYtel (a Telnet-only client)
>Plink (a command-line interface to the PuTTY back ends)
>Pageant (an SSH authentication agent for PuTTY, PSCP and Plink)
>PuTTYgen (an RSA and DSA key generation utility).

PuTTY commands are:
ls - to list files in a directory
cd - change directory
cp - copy a file
mv - move a file (also used to rename files)
rm - remove a file
mkdir - make directory
pwd - show your current location
whoami - find out which user you are
date - display date and time
and more.
