Chrony for Debian ----------------- Notes about Debian-specific changes: - Default chrony’s configuration files are located in the /etc/chrony directory. It is filled by two important files: → chrony.conf (configuration of the chronyd daemon, see man 5 chrony.conf for further information) → chrony.keys (lists keys used for NTP packets authentication, see the “keyfile” directive in the chrony.conf(5) man page) - We also provide /etc/ppp/ip-up.d/chrony and /etc/ppp/ip-down.d/chrony to put chronyd online/offline depending on the PPP link status. - Since version 1.31.1-1, we create the _chrony system user to which chronyd will drop root privileges on initialisation. For users already allowing chronyd to drop root privileges in favor of the user configured by the "user" directive in chrony.conf, your configuration will remain unchanged and will still work as it did. However, if you don’t want to deviate from Debian’s default configuration, delete or comment out the "user" directive in chrony.conf and recursively change the owner of the /var/lib/chrony and /var/log/chrony directories. For example: # sed -i 's/^user/#user/' /etc/chrony/chrony.conf # chown -R _chrony:_chrony /var/l{ib,og}/chrony -- Vincent Blut <vincent.debian@free.fr> Fri, 01 Mar 2019 19:02:12 +0100
