PuTTY is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including [SCP], SSH, [Telnet] and [rlogin]. The name "PuTTY" has no definitive meaning,[1] though "tty" is the name for a terminal in the [Unix] tradition, usually held to be short for [Teletype].

PuTTY was originally written for [Microsoft Windows], but it has been ported to various other operating systems. Official ports are available for some [Unix-like] platforms, with work-in-progress ports to Classic [Mac OS] and [Mac OS X], and unofficial ports have been contributed to platforms such as [Symbian][2][3] and [Windows Mobile].

PuTTY was written and is maintained primarily by Simon Tatham and is currently beta software.

Features

Some features of PuTTY are:

  • The storing of hosts and preferences for later use.
  • Control over the [SSH] encryption key and protocol version.
  • Command-line [SCP] and [SFTP] clients, called "pscp" and "psftp" respectively.
  • Control over port forwarding with SSH (local, remote or dynamic port forwarding), including built-in handling of [X11] forwarding.
  • Emulates most [xterm], [VT102] control sequences, as well as much of [ECMA-48] terminal emulation.
  • [IPv6] support.
  • Supports [3DES], [AES], [Arcfour], [Blowfish], [DES].
  • [Public-key] authentication support (no certificate support).
  • Support for local serial port connections.
  • Self-contained executable requires no installation.
  • Supports the zlib@openssh.com delayed compression scheme (As of r9120 2011-03-05).

Version history

PuTTY's development dates back to late 1998,[4] and it has been a usable SSH-2 client since October 2000.[5][6]

Components

PuTTY consists of several components:

  • 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
  • pterm: a standalone terminal emulator

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. We couldn't possibly comment on such allegations."
