config ntp client et serveur

Le Serveur

Les sources c’est là :
http://www.serveur-de-temps.fr/

Pour le serveur on install ntp :

apt-get install ntp

Le fichier de configuration se trouve dans /etc/ntp.conf

# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

driftfile /var/lib/ntp/ntp.drift


# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable


# You do need to talk to an NTP server or two (or three).
server ntp.ubuntu.com
server ntp.univ-reims.fr


# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details.  The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
#
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.

# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery

# Local users may interrogate the ntp server more closely.
restrict 127.0.0.1
restrict ::1

# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
#restrict 192.168.123.0 mask 255.255.255.0 notrust


# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
#broadcast 192.168.123.255

# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines.  Please do this only if you trust everybody on the network!
#disable auth
#broadcastclient

J’ai ajouter le serveur de reims, car il est toujours bon d’avoir au moins 2 serveurs de temps

Le Client

Le paquet ntp est installé par default

Le fichier de config :
/etc/default/ntpdate

NTPDATE_USE_NTP_CONF=yes

par default ntp conf est à oui donc j’ai créé le fichier
/etc/ntp.conf

son contenu :

server ntp.ubuntu.com
server pool.ntp.org

Même sans le fichier /etc/ntp.conf, le système se met à jour
