After providing an introduction to the Perl programming language, this helpful guide teaches computer networking using Perl. Topics discussed include ethernet network analysis, programming standard Internet protocols, and exploring mobile agent programming.
* Each chapter provides a general discussion of the technologies under consideration, the support for programming the technologies as provided by Perl, and implementations of working examples
* Covers Mobile Agent Technology, which is set to become one of the "next big things" on the Internet
* Further information is supplied, including a listing of Web and print resources, programming exercises, and tips to expand the reader's understanding of the material

Paul Barry is formally educated and trained in Computer Science and holds a Masters Degree in Computing Science. He has been programming professionally, on and off, for close to 20 years. Paul already has two textbooks to his name, and is also a Contributing Editor to Linux Journal magazine. His day job is with the Institute of Technology, Carlow in Ireland where he has spent over a decade preparing Ireland's next generation of computing folk to be productive in the workforce. His role as a lecturer affords him the opportunity to explore, learn and teach the very latest programming technologies and practices, which is something that he enjoys even though he knows this makes him a bonafide geek . Paul lives just outside the town of Carlow in Ireland with his wife, two sons, daughter, dog and cat. There's a bunch of computers and a growing collection of music instruments in the house, too (and like a lot of the Head First family, Paul is a struggling guitarist trapped inside a geek's body). He has so far resisted any suggestion that the family acquire a hamster ... or a set of drums.
