Tentacle is a client/server file transfer protocol that is:

• Safe by design.
• Easy to use and integrate with other tools.
• Versatile and cross-platform.

Tentacle was created to replace more complex tools like SCP and FTP for simple file transfer/retrieval, and switch from less safe authentication systems like .netrc, as well as automated interactive logins with expect, and SSH keys, to start using a certification based on the standard X.509, using certificates.

The client and server are designed to be run from the command line or called from a shellscript. Since 2008, Tentacle is the default file transfer method for Pandora FMS, replacing SCP.

Tentacle is implemented in Perl and ANSI C (Windows platforms included).

You can download it and find more information at the official Sourceforge project website.
