Implement a 'keep1daemon' service script about funz-calculator

[yannrichet]

Still better : 66b203f
this bash script wait for a network "hi" to start daemons, for many users (and just sleep when none is needed).
the "hi" should be implemented before Funz run: echo "hi"| curl -m 1 telnet://mybigserver:19000
the final "bye" should be called when all runs are finished: echo "bye"| curl -m 1 telnet://mybigserver:19000
