# 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 :

|
|
|
||
|
|
or
|
||
|
|
