CONFIG_FOLDER="/hamachi"
DELAY_SEC="1" # used if there is connection problems
# There are two obstacles to running Hamachi reliably under Linux:
# 1) not using delays between commands (the Hamachi server does not respond in time, and the login fails)
# 2) not logging out of the Hamachi server properly before an OS reboot.
# So, if you encounter issues, try execute the command "hamachi logout" before rebooting.
# This script can be added to /etc/init.d/ (under SuSE) to automatically log in/out of Hamachi.
# Once you copy the file to /etc/init.d/ you have to activate it (make it run on startup/shutdown)
# - On SuSE, go into Administrator settings, then System..System Services (RunLevel).
# - On other Linux distributions, there is a command add the script to the startup/shutdown sequence.
#
# Usage:
# hamachi-daemon.sh config # adds this machine to the network (network must already exist)
# hamachi-daemon.sh start # starts services
# hamachi-daemon.sh stop # stops services
# hamachi-daemon.sh restart # restarts services (used if there is issues connecting)
# hamachi-daemon.sh list # lists machines on the network
# Carry out specific functions when asked to by the system
