PuTTY user manual (copy from 2022)

PuTTY (

rlogin, and raw socket connection. It can also connect to a serial port. The name "PuTTY" has no official meaning.[5]

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 macOS, and unofficial ports have been contributed to platforms such as Symbian,[6][7] Windows Mobile and Windows Phone.

PuTTY was written and is maintained primarily by Simon Tatham, a British programmer.

Features

PuTTY supports many variations on the secure remote terminal, and provides user control over the

X11 forwarding). The network communication layer supports IPv6
, and the SSH protocol supports the [email protected] delayed compression scheme. It can also be used with local serial port connections.

PuTTY comes bundled with command-line

SFTP clients, called "pscp" and "psftp" respectively, and plink, a command-line connection tool, used for non-interactive sessions.[9]

PuTTY does not support

session tabs directly,[10] but many wrappers are available that do.[11]

History

PuTTY development began late in 1998,[1] and was a usable SSH-2 client by October 2000.[12][13]
