Daemons are time honored technique to implement services on Unix platforms.
Some distributed systems administration functions can be more effectively
implemented using daemons rather than rsh/ssh. Developing a new daemon each
time one is desired is a barrier to their use, since it's can be a
significant development task to implement one in a way that includes
advanced features like non-blocking I/O operations and handling multiple
clients concurrently.
Perl's IO::Socket and IO::Select modules are a great foundation for
building daemons. GPD uses these modules to implement a generic daemon that
can jumpstart application specific daemon development. In it's current
implementation just grab the GPD code and customize the IntCmd & ExtCmd
hashes to define your own functions or external commands.
Developed and tested w/ Perl 5.00503.
Specification.
General Purpose Daemons, is intended to be configurable to perform any type
of daemond/server functionality.
See 'gpd -h'.
Errors.
Just Beta for now.
This needs to become a Perl Library or Module so it's easier to distinguish
between the gpd package and the site implementation/customizations.
