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

# # dscomsa.desy.de
