The motive behind murder was to surface and extend the information that was once universally provided by finger(1) through a modern interface. Building on this, murder has a plug-in infrastructure to add additional features, allowing it to become a full-fledged social-information platform that utilizes standard and open technologies.
This is a much updated version of Mike Shanzer's fingerd-1.3. It is almost completely rewritten, well-debugged (i.e., more secure), and quite configurable. It supports ACLs, a message-of-the-day file, the ability to run programs for given user-IDs, and a full set of command-line options that make it mostly compatible with modern BSD versions. It is portable, uses GNU Autoconf and GNU Automake for builds, and it comes with a ready-to-use BSD makefile too.
PFinger is a highly configurable, secure and portable finger deamon. It is started by inetd but does not run as root. The service may be disabled for individual users by the administrator or by the users themselves. It offers configurable special files (e.g. a users PGP-Key could be retrieved with 'finger john.pgpkey@host), no printing of users home directory or shell and it also provides a graphical frontend that allows users to easily alter the output that will be sent, when they are fingerd.
Fingerbob is a simple Finger daemon which displays formatted user information from an LDAP directory. It is useful when you're in a dark corner of the server room without a GUI and need to find a phone number. Almost every networked computer has a finger client, so Fingerbob provides a simple but universal network address book. It can also provide text documents and list all people in a specified branch of the LDAP directory.
