Installation serveur NTP
Définir si réellement on a besoin d'un serveur de NTP (Network Time Protocol) local
Pour voir la liste des servers (document):
ntpq -p
L'installation du serveur NTP sur NUC est deja fait dans l'installation avec
apt-get install --no-install-recommends ntp -y
Pour reference, la configuration argos1 donne (/etc/ntp.conf (sans les commentaires):
driftfile /var/lib/ntp/drift restrict default kod nomodify notrap nopeer noquery restrict -6 default kod nomodify notrap nopeer noquery restrict 127.0.0.1 restrict -6 ::1 restrict 10.10.132.0 mask 255.255.255.128 nomodify notrap server hq-000-ds01.hq.eso.org server hq-000-ds02.hq.eso.org server sg5tim.ls.eso.org server tymeserve.ls.eso.org peer 10.10.132.82 maxpoll 6 includefile /etc/ntp/crypto/pw (rem ce fichier est pure commentaires) keys /etc/ntp/keys (rem ce fichier est pure commentaires)

Sur les LCUs, la config est:
glstreg (SL5.5):
restrict 10.10.132.0 mask 255.255.255.128 nomodify notrap peer glstser maxpoll 6 peer glstopt maxpoll 6il faut supprimer argos* et au moins mettre un serveur standard (ntp.ubuntu.com) dans /etc/ntpd.conf driftfile /var/lib/ntp/drift keys /etc/ntp/keys server argos1 maxpoll 6 server argos2 maxpoll 6
glsserv (SL6.7):
restrict 10.10.132.0 mask 255.255.255.128 nomodify notrap driftfile /var/lib/ntp/drift keys /etc/ntp/keys ntptrace server argos1 maxpoll 6 server argos2 maxpoll 6 server 134.171.104.25 server 134.171.81.175
glspc20 (SL5.5):

Sur les LCU (en test à geneve ou local)
On a mis:
lcu01: SL6.7
restrict 10.10.133.0 mask 255.255.255.128 nomodify notrap driftfile /var/lib/ntp/drift keys /etc/ntp/keys server 134.171.104.25 server 134.171.81.175 server ntp.ubuntu.com
lcu02: SL5.5 (Attention bug avec 132 au lieu de 133)
restrict 10.10.132.0 mask 255.255.255.128 nomodify notrap driftfile /var/lib/ntp/drift keys /etc/ntp/keys server 134.171.104.25 server 134.171.81.175 server ntp.ubuntu.com
