Bonjour,
 
Le serveur ntp local répond correctement aux demandes (serveurs, client, demande "manuelle" )
Malgré cela, j'ai des serveurs qui ne sont pas à l'heure (décalage progressif) malgré la présente d'un daemon ntp qui semble correctement effectué :
 
Code :
 - # /etc/ntp.conf, configuration for ntpd
 - driftfile /var/lib/ntp/ntp.drift
 - 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 <notre_serveur_ntp_local>
 - # 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
