Configuring ETKMSs
EncrypTight User Guide 51
8 At the command line, restart the ETKMS service by typing service etkms restart and press
Enter.
Verify the IP address and hostname changes (see “Verify the IP Address and Hostname Changes” on
page 49).
NOTE
● Make a note of the eth0 IP address and the hostname. You will need this information in order to add
the ETKMS in ETEMS.
● It is strongly recommended that you set a static IP address and turn off DHCP. Do not use DHCP to
obtain an IP address.
● If you are configuring a backup ETKMS, you must use the same type of IP address for the backup as
you used for the primary. For example, if the primary ETKMS was assigned an IPv6 address, you must
assign an IPv6 address to the backup.
● When you add the ETKMS in ETEMS, use the short hostname. For example, if the full hostname is
etkms1.mycompany.com, the ETKMS name is etkms1. In addition, the ETKMS name is case sensitive.

Configure Time and Date Properties
All EncrypTight components, including the ETKMS, should be synchronized with a time server,
preferably the same time server. Configure the time and date properties and then check the status of the
connection with the time source. You must be logged into the ETKMS as root to make these changes.
TIP
Before you configure the NTP service, you might want to use the Linux date command to set the system
clock. If there is a large difference between the hardware clock and the NTP server, it can take
significantly longer for the clock to synchronize with the server. You can learn about the Linux date
command from many online sources.
To set the time zone:
1 Edit the file
/etc/sysconfig/clock
2For the Zone value, specify the appropriate filename. Zone files are located in:
/usr/share/zoneinfo
Include the parent directory in the entry (for example, America/New_York).
3 Save and close the file.
To set up time synchronization:
1 Edit the file:
/etc/ntp.conf
