Oracle^® SuperCluster M8 and SuperCluster M7 Security Guide

Enable Sendmail and NTP Services

The sendmail service must be running, otherwise important system mail to root is not delivered.

1. Log in to one of the compute servers and access the host console as superuser.

   See Log into a Compute Server.

2. Enable sendmail.

   # svcadm enable smtp:sendmail
   

3. If needed, install the NTP service.

   The ntp service must be installed on all systems where security and compliance is desired.

   # pkg install service/network/ntp
   

4. Configure the NTP service as a client and enable the service.

   The Network Time Protocol daemon must be enabled and properly configured as a client. The /etc/inet/ntp.conf file must include at least one server definition. The file must also contain the line restrict default ignore to prevent the client from also acting as a server.

   # vi /etc/inet/ntp.conf
   . . .
   server server_IP_address iburst
   restrict default ignore ...
   # svcadm enable ntp
