This page contain information about Generic Security Service (GSS), a free implementation of RFC 2743/2744.
If you do not know what GSS is, I suggest to read the following resources.
GSS itself is licensed under GPLv3+, and the manual is licensed under GFDLv1.3+.
Refer to the GSS Manual web page for links to the manual in all formats; however, quick links to the most popular formats:
GSS has received some real-world testing and should be considered beta quality.
The source code framework is in place, an outline of the documentation is ready, and there are some simple self tests. The Kerberos 5 mechanism (RFC 1964 and RFC 4121) supports mutual authentication, channel bindings and the standard DES cipher. The non-standard 3DES cipher is also implemented, but unfortunately there are no specifications for AES. GNU SASL can use GSS to connect to GNU Mailutils and Cyrus IMAP servers that use the GSS implementations from MIT Kerberos or Heimdal. GNU MailUtils can also use GSS to serve GSSAPI clients. A SSH client and server with GSS authentication is provided by LSH with some patches.
GSS is developed for the GNU/Linux system, but runs on over 20 platforms including most major Unix platforms and Windows, and many kind of devices including iPAQ handhelds and S/390 mainframes.
GSS uses GNU Shishi to implement the Kerberos V5 mechanism.
Projects using GSS include:
A mailing list where GSS users may help each other exists, and you can reach it by sending e-mail to email@example.com. Archives of the mailing list discussions, and an interface to manage subscriptions, is available through the World Wide Web at http://lists.gnu.org/mailman/listinfo/help-gss.
If you find GSS useful, please consider making a donation. No amount is too small!
The releases are distributed from ftp://ftp.gnu.org/gnu/gss/.
git clone git://git.savannah.gnu.org/gss.git
The online git interface is available.
See the file README-alpha on how to bootstrap and build the package from version controlled sources.
