Installing K-Secure VPN™ Server On Linux

I. Prerequisites

  1. A Linux distribution with kernel 2.x or better (tested on 2.4.21) running on X86 Architecture;
  2. At least 10MB free disk space;
  3. At least 10MB free memory;

II. Installation

  1. Download the latest release from http://k-secure.com/download.php;
  2. Extract all contents from the archive into a directory;
  3. chdir into the directory where all files are extracted;
  4. Carefully examine the sample INI file (KsVpnSvr.ini), make changes to the [Options] section;
  5. You may add more groups, rules or users into the INI file by following the samples in the INI file;
  6. Type the following command in your shell to import the INI file:
        ./KsVpnSvr --import=KsVpnSvr.ini
  7. To export a configuration for a particular user, see section III below.
  8. Type the following command in your shell
        ./KsVpnSvr
    or
        ./KsVpnSvr &
    to start the server.

III. Export Configurations

Type the following command in your shell to export configuration file for a user:
    ./KsVpnSvr --ExportConfig=Username
where Username is the username of the user that you defined in the INI file. Note Username is case sensitive.

For example, if you are to export the configurations for John, type
    ./KsVpnSvr --ExportConfig=John
This command will generate John.kvr in the current directory. You can redistribute this file to John so he can import this file in the client machine.

IV. Testing

Please see http://k-secure.com/ksvpnsvr/webhelp/QuickTutorial.php for a step-by-step tutorial on how to get the server up and running. This tutorial is written for Windows users, however the concept and test steps are virtually the same for Linux servers.

V. Database Transferring

You may follow the tutorial to set up your server on Windows platform and then transfer the resulted KsVpnSvr.db to your Linux installation directory. Just remember that in "Step 1: Verify External IP and Port," the "External IP" shall be defined as the IP of your Linux box and not that of the Windows machine. On Windows XP and earlier Windows, KsVpnSvr.db resides in
    C:\Documents and Settings\All Users\Application Data\K-Secure
On Windows Vista and Windows 7, KsVpnSvr.db resides in
    C:\ProgramData\K-Secure
If your Windows OS is installed on a different hard disk, say drive D:, then replace "C:" with "D:" in the previous paths.

VI. Sample Runs
