This article needs additional citations for . verification (July 2011) PuTTY ( / / ) is a [2 ] free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection. The name "PuTTY" has no definitive meaning, though "tty" is the name for a terminal in the [3 ] 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 [4 ] and [5 ] Windows Mobile.
PuTTY was written and is maintained primarily by
Simon Tatham and is currently beta software. Features [edit ]
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 firstname.lastname@example.org delayed compression scheme (as of r9120 2011-03-05) History [edit ]
PuTTY's development dates back to late 1998,
and it has been a usable SSH-2 client since October 2000. [1 ] [6 ] [7 ] Components [edit ]
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 See also [edit ] References [edit ] External links [edit ]
