Client NTP

Almalinux Linux 8/9 - Rocky Linux 8/9 - Centos 8

Coté client :

dnf install chrony ; systemctl enable chronyd

On remplace le serveur NTP standard par celui de Behostings / Diogenius.

Pool NTP standard : pool 2.almalinux.pool.ntp.org iburst

NTP Behostings : server ntp.dgnus.net iburst

sed -i -e '/ iburst/d' /etc/chrony.conf

echo "# server ntp Behostings - Diogenius" >> /etc/chrony.conf
echo "server ntp.dgnus.net iburst" >> /etc/chrony.conf

systemctl restart chronyd ; chronyc sources ; chronyc sourcestats -v ; chronyc activity

[root@test]# systemctl restart chronyd ; chronyc sources
