It's been rumoured that ‘PuTTY’ is the antonym of ‘getty’, or that it's the stuff that makes your Windows useful, or that it's a kind of plutonium Teletype. Any other meaning is in the eye of the beholder. If you have a Linux server running OpenSSH, connecting to it through SSH from a remote system can come in very handy for administration purposes.Mac and Linux come with SSH clients that can help connecting to remote servers while Windows users are left in the dark.
the name of a popular SSH and Telnet client. This post describes how to install PuTTY on Windows systems. Usually used for SSH Tunneling Pageant an SSH authentication agent for PuTTY, PSCP and Plink PuTTYgen an RSA, DSA, ECDSA and EdDSA key generation utility pterm (Unix version only) an X11 client which supports the same terminal emulation as PuTTY See also general file transfer sessions much like FTP PuTTYtel a Telnet-only client Plink a command-line interface to the PuTTY back ends. Can also use SFTP to perform transfers PSFTP an SFTP client, i.e.
PuTTY the Telnet, rlogin, and SSH client itself, which can also connect to a serial port PSCP an SCP client, i.e. PuTTY development began late in 1998, and was a usable SSH-2 client by October 2000. PuTTY does not support session tabs directly, but many wrappers are available that do. PuTTY comes bundled with command-line SCP and SFTP clients, called "pscp" and "psftp" respectively, and plink, a command-line connection tool, used for non-interactive sessions. It can also be used with local serial port connections. The network communication layer supports IPv6, and the SSH protocol supports the delayed compression scheme. It also can emulate control sequences from xterm, VT220, VT102 or ECMA-48 terminal emulation, and allows local, remote, or dynamic port forwarding with SSH (including X11 forwarding). PuTTY supports SSO through GSSAPI, including user provided GSSAPI DLLs. PuTTY uses its own format of key files – PPK (protected by Message Authentication Code). Some terminal control sequences like the Linux console sequences which are unsupported by xterm are supported by PuTTY.PuTTY supports many variations on the secure remote terminal, and provides user control over the SSH encryption key and protocol version, alternate ciphers such as AES, 3DES, RC4, Blowfish, DES, and Public-key authentication. Many variations on the secure remote terminal are supported by PuTTY. It has an easy-to-use graphical user interface. It is also more persistent in comparison to others, as a remote session can be resumed as soon the connection is restored after an interruption. It is easier to configure and is more stable. PuTTY provides some distinct advantages, especially when working remotely. With regards to cut and paste features, PuTTY can be customized to act similarly to xterm. For reducing the unpredictability of random data, PuTTY makes use of a random number seed file which is usually stored in PUTTY.RND file. The main window of PuTTY has the session which runs on the remote computer and through which one can send the commands directly to the remote computer. Most features like port forwarding and public keys are available through the command line options. It even specifies its terminal type as xterm to the server although this can be reconfigured. It can be considered like an xterm terminal for most purposes.
The primary goal of PuTTY is to become a multi-platform application capable of executing in most operating systems.
