A bit of a status update on Scooby. It really only works reliably under 5.6.1 of Perl. There turned out to be too many module dependencies/breakages when Perl got updated, and I've not had the time to work out what has to happen to Scooby and its 3rd party modules to fix things - I have tried Scooby with a bunch of the latest Perls, but it breaks in a number of places (mainly the 3rd party modules break or cause Scooby to break). In summary, Scooby was created to test the assumption that a debugger-type interface could be used to access a programs "state" prior to relocation. The project showed that this was the case. For my part, I actually think the Agent Perl technology offers a better platform to build on (that's why I put it in my first book - I was hoping it would draw attention to the technology and help it catch on).

Ok - swallows hard - here goes. I've spent the last little while working on a new mobile agent system for Perl. Called "Scooby", it provides for reliable and secure (authenticated and encrypted) transportation of "strongish" mobile agents from computer to computer. For more details, please visit the Scooby website at: http://glasnost.itcarlow.ie/~scooby/ and read the Installation/Configuration instructions, in addition to "The Scooby Guide", which is a programmers guide for mobile agent writers (available as a PDF). The software can also be downloaded from here (it will be added to CPAN soon). Note that Scooby has some heavy module requirements (mainly brought about by the use of the Crypt::RSA module, which has LOADS of prereqs). You will also need to have MySQL running to support the Key Server. At the moment, it ONLY works with 5.6.1 of Perl, as anything else has given me problems. (My 5.8.0 installation of Perl has problems with Crypt::RSA, unfortunately). At the moment, I'd classify the maturity of this code as "beta". Have fun! And, of course, let me know what you think.

I also think I don't have the time to tackle that on short notice. But I've some ideas on an agent framework that's written in Perl,e.g. itinerary, transport and the agent object by itself. Although you should separate the agent from the transport over which it has been transported, I would like to experiment with jabber as a possible transport medium ... Maybe I'lll brew something myself, but I'm afraid it won't be standards compliant ...

But it's true - I'd like to see the ball rolling and would be willing to help, though my time is limited ATM. Anyways, there has been talk of new initiatives, but as of yet, none are under way... I've had some interesting chats with Ben Evans sporadically over the past few months where we'd talked about a new framework, in particular trust mechanisms, and Perl modules for OWL & DAML/OIL, which in turn would require a namespace-aware RDF framework... I'd also had some conversations a while back with Matt Lawrence about modelling a new framework on the work done by FIPA (www.fipa.org - which contains more ideas than you could shake a stick at... :), and with Tim Finin on the evolution of KQML/KIF to OWL. (All of this was sparked by Paul's interest, so thanks Paul!) If a new initiative is going to happen, I'd suggest it start by: 1. Reviewing the current system, picking out good & bad points. 2. Talking about what's going on in the world of agents, and making proposals about what a perl agent system should be/do. 3. Decide & agree on what to build. 4. Build it.

I see the server not really giving a rats ass about anything higher than the transport layer. So it wouldn't know about the ACL/OWL/perl/english/etc. messages that it let agents send. That way seperate API's could be written for ACL/OWL and release on CPAN... Of course, to go with the spirit of ACL & collaborating agents, you'd have to write some standard agents that know about ACL/OWL, and act accordingly (like getting an 'ask-all' ACL message, and actually asking all its contacts. or getting a 'host-me-pls' PERL kinda message, and hosting a mobile agent). So maybe writing a set of example agents would be the third task that glues it all together. +-- Steve Purkis <spurkis@epn.nu> http://www.nntp.perl.org/group/perl.agents/2002/08/msg4.html Thu, 15 Aug 2002 04:13:50 +0000 Is anybody out there? by Paul Barry Hi! I used to be on the 'old' list some time ago, and Steve Purkis has just directed me to this one which I guess is now the "official list" ( ... now I know why things were so quiet). In February last, Wiley Computer Publishing published my book, "Programming the Network with Perl", which includes a chapter on using Agent Perl (v3.20) to write mobile agents. After describing the development of a set of programs that can form the basis of a mobile agent system, I use the system to write the 'classic' mobile agent distributed 'who' as well as a more involved mobile agent network management application. (The previous chapter in the book covers using Perl to program SNMP). I'd be interested in hearing from others on this list who have read the book. I'm particluarly keen to hear from other Agent Perl programmers. Find out more about the book here: http://glasnost.itcarlow.ie/~pnb/index.html Thanks.
