Service ping-pong

This service is a brain-dead application. It is only to a pedagogic end.

The purpose is only to communicate with an application once, the application sends a message and the service answer with the same message.

How it works

  • S: service
  • A: application
  1. S creates the named pipe /tmp/pingpong, then listens
  2. S opens the named pipes in & out
  3. A talks with the test program pingpong.sh
  4. S closes the test program named pipes
  5. S removes the named pipe /tmp/pingpong after 10 served applications

pingpong.sh

The script pingpong.sh lets you test the service.

Usage :

pingpong.sh [NB]
# NB is the number of exchanged messages

or

pingpong.sh clean
# it is to clean the /tmp/ipc/ directory
