# 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
```

**Ou manuellement :**

edit :

```
nano /etc/chrony.conf
```

Commenter la pool ntp standard et ajouter le nouveau serveur : server ntp.dgnus.net iburst

```
systemctl restart chronyd ; chronyc sources
```
