Ntp
NTP is Network Time Protocol. It exists on both Solaris and Linux but is not started by default so it must be started using following procedure:
Solaris
1. login to clon01 as root
2. Create file /etc/inet/ntp.conf (see example)
3. svcadm enable network/ntp - starts the xntp daemon; check it:
4. svcs | grep ntp
online 16:29:30 svc:/network/ntp:default
5. ntpq -p

-
- chkconfig --add ntpd (normally linux has it already)
chkconfig --level 3 ntpd on chkconfig --level 4 ntpd on chkconfig --level 5 ntpd on chkconfig --list ntpd (last command prints: ntpd 0:off 1:off 2:off 3:on 4:on 5:on 6:off)
