Subject: chrony 1.1 sysV startup script for notebooks


Dear Richard,

I installed chrony on my notebook, running RedHat 5.1 Linux.
It looks like it works.  No problems.

Thank you!

I like to donate my sysV startup script, appended below.

Special feature:  the `online' command scans the config file to
selectively turn some servers online, depending on the pcmcia SCHEME.

booting:                 /etc/rc.d/init.d/chrony start
/etc/ppp/ip-up:          /etc/rc.d/init.d/chrony online
/etc/ppp/ip-down:        /etc/rc.d/init.d/chrony offline
logrotate cron:          /etc/rc.d/init.d/chrony cyclelogs
a user:                  /etc/rc.d/init.d/chrony status
a sysadmin:              /etc/rc.d/init.d/chrony restart
shutdown:                /etc/rc.d/init.d/chrony stop

Best regards
Stephan

# For PCMCIA users:
# In /etc/chrony.conf, precede the server commands for each SCHEME 
# with a comment line that contains the word SCHEME and the name of
# the scheme(s) that should use the servers, up to the next line that
# contains the word SCHEME.  The servers must be `offline' and 
# specified by their IP address.  The hostname will not do.
#
# Like:
#
#	# SCHEME nevisppp nevislan
#	#       stephanpc.nevis.columbia.edu
#	server  192.12.82.222   offline
#
#	# SCHEME desyppp desylan
#
#	#       dsygw2.desy.de
#	server  131.169.30.15   offline
#	#       dscomsa.desy.de
#	server  131.169.197.35  offline
