# dasscm_remote_check is intended for systems
# where a local dasscm installation is not possible
# but ssh and rsync is available.
# Use dasscm_remote_update to update the configuration files,
# and the corresponding dasscm_remote_check to perform the
# related nagios check.
# Use only, if a local dasscm installation is not possbile!
