# This script perform a test of the time servers whose names
# can be found into the variables
# - $server1
# - $typedserver1
# - $server2

# The typed variables have precedence over the fixed, if they are not empty.
# This test  (ntpdate...) have a fixed timeout.
# If the test succeeds, it calls the script save_config.sh and then outputs 'ciao'
# else, it outputs 'server_not_responding'
