Lanzado Putty 0.59 beta

PuTTY, el más famoso de los clientes SSH ha lanzado recientemente una nueva versión (0.59 beta).

Su popularidad se debe en gran medida a que permite la conexión a un servidor Linux desde cualquier maquina con Microsoft Windows, ademas PuTTY posee una excelente emulación de la terminal ANSI de Linux.

Se pueden descargar ejecutables para Windows y código fuente para Windows y Unix.

Tambien hay que destacar que el programa es gratuito y su código es abierto.

Estas son los cambios:

• PuTTY can now connect to local serial ports as well as making network
  connections.
• Windows PuTTY now supports "local proxying", where a network
  connection is replaced by a local command. (Unix PuTTY has supported
  this since it was first released in 0.54.) Also, Plink has gained a
  "-nc" mode where the primary channel is replaced by an
  SSH tunnel, which makes it particularly useful as the local command
  to run.
• Improved speed of SSH on Windows (particularly SSH-2 key exchange and
  public-key authentication).
• Improved SFTP throughput.
• Various cryptographic improvements in SSH-2, including SDCTR cipher
  modes, a workaround for a weakness in CBC cipher modes, and
  Diffie-Hellman group exchange with SHA-256.
• Support for the Arcfour cipher in SSH-2.

• Support for sending terminal modes in SSH.

• When Pageant is running and an SSH key is specified in the
  configuration, PuTTY will now only try Pageant authentication with
  that key. This gets round a problem where some servers would only
  allow a limited number of keys to be offered before disconnecting.
• Support for SSH-2 password expiry mechanisms, and various other
  improvements and bugfixes in authentication.
• A change to the SSH-2 password camouflage mechanism in 0.58 upset some
  Cisco servers, so we have reverted to the old method.
• The Windows version now comes with documentation in HTML Help
  format. (Windows Vista does not support the older WinHelp format.
  However, we still provide documentation in that format, since Win95
  does not support HTML Help.)
• On Windows, when pasting as RTF, attributes of the selection such as
  colours and formatting are also pasted.
• Ability to configure font quality on Windows (including antialiasing
  and ClearType).
• The terminal is now restored to a sensible state when reusing a window
  to restart a session.
• We now support an escape sequence invented by xterm which lets the
  server clear the scrollback (CSI 3 J). This is useful for applications
  such as terminal locking programs.

• Improvements to the Unix port:
  • now compiles cleanly with GCC 4
  • now has a configure script, and should be portable to
    more platforms
