Synchronizing times with Linux

Synchronizing times with the Linux/Solaris operating system

You can synchronize the system time with the Linux operating system as well. For this, please apply the procedure outlined below.

Before you set up the service you should test the ipNTP connection with a ping.

For Linux systems, please type the command "ping –s 32 IP-Address" in the
command shell.

For Solaris systems, please type the command "ping –s IP-Address 32" in the
command shell.

With the command

/usr/sbin/ntpdate "Server IP or Server Name"

the system time is synchronised with the server once. If you want your system time to be regulary synchronized with the NTP server, there are several possibilities, for example, you
can perform a registered cronjob at the crontab. If you want to synchronize your
system time at 3:30 on a daily basis, please enter the command:

30 3 * * * /usr/sbin/ntpdate "Server-IP or Server Name"


For further information, please read the "man" pages:

man ntpdate
man crontab
man ntpd
man xntpd
