HOBLink VPN Gateway Introducing HOBLink VPN Gateway
Security Solutions by HOB 9
1.4 Components of HOBLink VPN Gateway
HOBLink VPN Gateway is a complete software solution that is delivered in a
modular form. These modules, both core modules and configuration modules, are
installed together and work together to provide the functionality you require.
1.4.1 Core Modules
There are two core modules that provide the required functionality of HOBLink VPN
Gateway. These are the:

Process Modules

Library Modules
Process Modules
The basic functionality of HOBLink VPN Gateway is provided by the process
hobvpn2
(main process). An important process,
hobsr
, provides
hobvpn2
with
added system resources and therefore needs special root permissions.
Another process,
sendsig
, sends two signals to the
hobvpn2
process. These
signals provide the following tasks:

sendsig
(sent without any parameter) - this signal indicates to the
hobvpn2
process that the configuration has been changed while the VPN is still running.
The
hobvpn2
process then reads the configuration file again and updates its in-
ternal processes accordingly, while it continues running.

sendsig hobvpn2
- this forces the
hobvpn2
process to stop running
Library Modules
Some libraries are needed for a proper connection:

libgcc_s.so.1

libhobxcw3.so

libhvpnintf32.so

+.so.6.0.14 (this has a link called +.so.6).
1.4.2 Configuration Modules
The configuration modules are the files that contain the necessary data needed by
HOBLink VPN Gateway to fulfill the tasks required of it.

vpnconfig.xml
– this file contains the configuration data that
HOBLink VPN Gateway needs to establish IKE/IPsec connections. It is located
in the installation folder
/HOB/HOBLinkVPN
of the application. For configuration
purposes, this file may either be edited directly or via a browser (either locally or
remotely), in which case the configuration server must be correctly configured.
