Overview

Many Kerio Control features (user authentication, logs, statistics, etc.) require the correct setting of the date, time, and time zone on the firewall. Kerio Control allows manual settings or synchronization with an NTP server (Network Time Protocol) as the best-practice recommendation. This article describes the process to follow in order to configure date, time, time zone, and server name for Kerio Control.

Solution

Configuring Date and Time

Many Kerio Control features (user authentication, logs, statistics, etc.) require the correct setting of the date, time, and time zone on the firewall. Kerio Control allows manual settings or synchronization with an NTP server (recommended).

1. In the Administration interface, navigate to Advanced Options > System Configuration.
   
2. Select the option Keep synchronized with NTP server. Date and time can be set manually but it is better to use an NTP server that provides information about the current time and allows automatic management of the firewall's system time. Kerio Technologies offers the following free NTP servers for this purpose:
   • 0.kerio.pool.ntp.org,
   • 1.kerio.pool.ntp.org,
   • 2.kerio.pool.ntp.org.
   • 3.kerio.pool.ntp.org.
3. Click on Apply.

Configuring Time Zone

1. In the Administration interface, navigate to Advanced Options > System Configuration.
2. Select a time zone from the Server time zone list.
3. Click on Apply. The current date and time will be changed according to the new time zone.

Configuring the Server Name

The default Kerio Control hostname is control. To change the hostname, connect to a directory service or change the web interface URL in the Advanced Options > Web Interface tab > Use specified hostname field.

In addition to this, the hostname needs to be changed in a configuration file using the below steps:

1. Log in to Kerio Control via SSH.
2. Edit the winroute.cfg file using the command nano /opt/kerio/winroute/winroute.cfg.
3. Find the Misc table. The entry looks like <table name="Misc">.
4. Edit the value of the Hostname variable as per your requirement. As per the above screenshot, it will be changed to <variable name="Hostname">control.local</variable>
5. Save your changes and exit the editor.
