Bell Labs/Lucent Technologies Not-So-Bad Distribution

From Higher Intellect Vintage Wiki
Jump to navigation Jump to search

An open, WWW-based authenticating software distribution system. Enhances simple Web downloads by authenticating maintainers of packages with digital signatures. It checks for updates to the packages and then downloads and installs them. This "automated pull" style of distribution has the same effect as the "push" style, with more control to the user. A direct "push" style is also supported; it is not used as frequently, but is appropriate for situations where there are multiple contributors to a shared server. NSBD uses "Pretty Good Privacy" (PGP) for authentication. Its focus is on security, leaving as much control as practical in the users' hands. Handles the operations done by both maintainers of packages and users of packages. This is free software, released under the terms of the GNU General Public License. Binaries are available for a variety of UNIX platforms, including Sunos4 and Solaris, and the source code is also available. It is written in TCL/TK and C. It is portable to most UNIX platforms.
