CONFIGURATION

Kerio Control VPN Client for Linux supports only one VPN connection at a time. During the package installation, a configuration wizard is automatically started. The wizard will ask for the server name/address, username, password and it offers an automatic detection of the server’s certificate fingerprint (for server identity verification).

Alternatively, the server’s certificate fingerprint may be entered manually.

If you want to change the configuration later, run the wizard again by invoking the following command:

# dpkg-reconfigure kerio-control-vpnclient

Alternatively, it is possible to manually edit the configuration file:

/etc/kerio-kvc.conf

After any changes to this file, it is necessary to reload the configuration:

# /etc/init.d/kerio-kvc reload

HOW TO VERIFY THE SERVER’S CERTIFICATE FINGERPRINT?

To make sure that the detected server’s certificate fingerprint matches the desired server, take the following steps:

1. Open the Administration Console for particular Kerio Control server.
2. Go to the Configuration / Interfaces section.
3. Open the VPN Server properties.
4. Compare the content of the Fingerprint field with the automatically detected certificate fingerprint.

STARTING / STOPPING

Kerio Control VPN Client will be automatically started after installation and restarted after reconfiguration.

You can start/stop it manually by invoking the command:

# /etc/init.d/kerio-kvc {start|stop|restart}

UNINSTALLATION

To uninstall Kerio Control VPN Client, remove the installed package:

# apt-get remove kerio-control-vpnclient
