All TRITON solutions

Before installing any TRITON solution, make sure that you have completed all of the preparations noted below:

Windows-specific considerations

Make sure all Microsoft updates have been applied. There should be no pending updates, especially any requiring a restart of the system.

In addition to the space required by the installer itself, roughly 2 GB of disk space is required on the Windows installation drive (typically C) to accommodate temporary files extracted as part of the installation process.

For information on disk space requirements, see Hardware requirements.

The TRITON Unified Installer requires .NET Framework v3.5 and 4.5.

For Windows server 2008 R2 SP1, you can add .NET 3.5 from Server Manager\Features. Usually this feature is On by default. You must download .NET 4.5 from the Microsoft site, https://msdn.microsoft.com/en-us/library/5a4x27ek%28v=vs.110%29.aspx?f=255&MSPPError=-2147217396.

For Windows server 2012/2012 R2, you can add both .NET 3.5 and .NET 4.5 from Server Manager\Features. Usually v3.5 is Off by default and v4.5 is On by default. Turn them both on.

Getting the software installers

The TRITON Unified Installer is used to install or upgrade the TRITON management server, web and data protection solutions, email protection management and reporting components, and SQL Server 2008 R2 Express on supported Windows servers.

There are separate installers for installing web protection components on supported Linux servers.

Download the Windows and Linux installers from the My Account section of forcepoint.com.

The (Windows-only) TRITON Unified Installer executable is named TRITON83xSetup.exe. Double-click it to start the installation process.

If you have previously run the installer on a machine, and you selected the Keep installation files option, you can restart the installer without extracting all of the files a second time.

Windows Server 2012: Go to the Start screen and click the Websense TRITON Setup icon.

Windows Server 2008 R2 SP1: Go to Start > All Programs > Websense > Websense TRITON Setup.

Note that the files occupy approximately 5 GB of disk space.

The web protection Linux installer is Web83xSetup_Lnx.tar.gz.

The Content Gateway Linux installer is ContentGateway83xSetup_Lnx.tar.gz.

Domain Admin privileges

TRITON components are typically distributed across multiple machines. Additionally, some components access network directory services or database servers. To perform the installation, it is a best practice to log in to the machine as a user with domain admin privileges. Otherwise, components may not be able to properly access remote components or services.


	Important If you plan to install SQL Server 2008 R2 Express and will use it to store and maintain data for your web protection solution, log in as a domain user to run the TRITON Unified Installer.

Synchronizing clocks

If you are distributing components across different machines in your network, synchronize the clocks on all machines where a TRITON component is installed. It is a good practice to point the machines to the same Network Time Protocol server.


	Note If you are installing components that will work with a TRITON appliance, you must synchronize the machine's system time to the appliance's system time.

Antivirus

Disable any antivirus on the machine prior to installing TRITON components. Be sure to re-enable antivirus after installation. Certain files should be excluded from antivirus scans to avoid performance issues; see Excluding Forcepoint files from antivirus scans.

No underscores in FQDN

Do not install TRITON components on a machine whose fully-qualified domain name (FQDN) contains an underscore. The use of an underscore character in an FQDN is inconsistent with Internet Engineering Task Force (IETF) standards.


	Note Further details of this limitation can be found in the IETF specifications RFC-952 and RFC-1123.

Disable UAC and DEP

Before beginning the installation process, disable User Account Control (UAC) and Data Execution Prevention (DEP) settings, and make sure that no Software Restriction Policies will block the installation.

TRITON Manager

In addition to the other general preparation actions described in this section:

Do not install the TRITON Manager on a domain controller machine.

If you want to run Microsoft SQL Server on the TRITON management server, use the TRITON installer to install SQL Server 2008 R2 Express.

If you are using a remote installation of SQL Server, you can use any of the supported versions (see System requirements for this version).

SQL Server 2008 R2 Express

The following third-party components are required to install Microsoft SQL Server 2008 R2 Express. Although the TRITON installer will install these components automatically if they are not found, it is a best practice to install the components first, before running the TRITON installer.

.NET Framework 3.5 SP1

Because the installer also requires .NET 4.5, both .NET 4.5 and .NET 3.5 SP1 are required if you are installing SQL Server Express.

Windows Installer 4.5

Windows PowerShell 1.0

PowerShell is available from Microsoft (www.microsoft.com).

If you will use SQL Server 2008 R2 Express to store and maintain data for your web protection solutions, log in to the machine as a domain user to run the TRITON installer. This ensures that Service Broker, installed as part of SQL Server 2008 R2 Express, can authenticate itself against a domain (required).

Web protection components

In addition to the general preparation actions (above), TRITON AP-WEB and Web Filter & Security components have the following additional requirements.

Filtering Service Internet access

To download the Master Database and enable policy enforcement, each machine running Filtering Service must be able to access the download servers at:

download.websense.com

Make sure that these addresses are permitted by all firewalls, proxy servers, routers, or host files that control the URLs that Filtering Service can access.

Firewall

Disable any firewall on the machine prior to installation. Be sure to disable it before starting the installer, and then re-enable it after installation. Open ports as required by the components you have installed.


	Note The TRITON installer adds two inbound rules to the public profile of Windows Firewall. Ports 9443 and 19448 are opened for TRITON Infrastructure. These ports must be open to allow browsers to connect to the TRITON Manager. Also, additional rules may be added to Windows Firewall when installing TRITON AP-DATA components.

See Default ports for on-premises TRITON solutions for more port-related information.

Computer Browser Service

To run User Service or DC Agent on a supported Windows server, the Computer Browser Service must be running.

On most machines, the service is disabled by default.

If the service is stopped, the installer will attempt to enable and start it. If this fails, the component installs and starts, but users are not identified until you enable and start the Computer Browser service.

Network Agent

If you are installing Network Agent, ensure that the Network Agent machine is positioned to be able to monitor and respond to client Internet requests.

In standalone installations (which do not include Content Gateway or a third-party integration product), if you install Network Agent on a machine that cannot monitor client requests, basic policy enforcement and features such as protocol management and Bandwidth Optimizer cannot work properly.


	Important Do not install Network Agent on a machine running a firewall. Network Agent uses packet capturing that may conflict with the firewall software.

The network interface card (NIC) that you designate for use by Network Agent during installation must support promiscuous mode. Promiscuous mode allows a NIC to listen to IP addresses other than its own. If the NIC supports promiscuous mode, it is set to that mode during installation. Contact your network administrator or the manufacturer of your NIC to see if the card supports promiscuous mode.

On Linux, do not choose a NIC without an IP address (stealth mode) for Network Agent communications.


	Note If you install Network Agent on a machine with multiple NICs, after installation you can configure Network Agent to use more than one NIC. See the Network Agent Quick Start for more information.

Network Agent using multiple NICs on Linux

If Network Agent is installed on a Linux machine, using one network interface card (NIC) for blocking and another NIC for monitoring, make sure that either:

The blocking NIC and monitoring NIC have IP addresses in different network segments (subnets).

You delete the routing table entry for the monitoring NIC.

If both the blocking and monitoring NIC on a Linux machine are assigned to the same subnet, the Linux operating system may attempt to send the block via the monitoring NIC. If this happens, the requested page or protocol is not blocked, and the user is able to access the site.

Installing on Linux

Most web protection components can be installed on Linux. If you are installing on Linux complete the instructions below.

SELinux

Before installing, if SELinux is enabled, disable it or set it to permissive.

Linux firewall

If web protection software is being installed on a Linux machine on which a firewall is active, shut down the firewall before running the installation.

Open a command prompt.

Enter service iptables status to determine if the firewall is running.

If the firewall is running, enter service iptables stop.

After installation, restart the firewall. In the firewall, be sure to open the ports used by components installed on this machine. See Default ports for on-premises TRITON solutions.


	Important Do not install Network Agent on a machine running a firewall. Network Agent uses packet capturing that may conflict with the firewall software. See Network Agent.

Hostname

If, during the installation, you receive an error regarding the /etc/hosts file, use the following information to correct the problem.

When installing to a Linux machine, the hosts file (by default, in /etc) should contain a hostname entry for the machine, in addition to the loopback address. (Note: you can check whether a hostname has been specified in the hosts file by using the hostname -f command.)

To configure hostname:

Set the hostname:

hostname <host>

Here, <host> is the name you are assigning this machine.

Also update the HOSTNAME entry in the /etc/sysconfig/network file:

HOSTNAME=<host>

In the /etc/hosts file, specify the IP address to associate with the hostname. This should be static, and not served by DHCP. Do not delete the second line in the file, the one that begins with 127.0.0.1 (the IPv4 loopback address). And do not delete the third line in the file, the on that begins ::1 (the IPv6 loopback address). Also, do not add the hostname to the second or third line.

<IP address> <FQDN> <host>
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

Here, <FQDN> is the fully-qualified domain name of this machine (i.e., <host>.<subdomains>.<top-level domain>)—for example, myhost.example.com—and <host> is the name assigned to the machine.


	Important The hostname entry you create in the hosts file must be the first entry in the file.

TCP/IP only

Web protection software supports only TCP/IP-based networks. If your network uses both TCP/IP- and non-IP-based network protocols, only user requests in the TCP/IP portion of the network are managed.

TRITON AP-DATA

See below for information about preparing to install TRITON AP-DATA components.

Do not install TRITON AP-DATA Server on a DC

Do not install TRITON AP-DATA Server on a domain controller (DC) machine.

Domain considerations

The servers running the TRITON AP-DATA software can be set as part of a domain or as a separate workgroup. If you have multiple servers or want to perform run commands on file servers in response to discovery, we recommend you make the server or servers part of a domain.

However, strict GPOs may interfere and affect system performance, and even cause the system to halt. Hence, when putting TRITON AP-DATA servers into a domain, it is advised to make them part of organizational units that don't enforce strict GPOs.

Also, certain real-time antivirus scanning can downgrade system efficiency, but that can be relieved by excluding some directories from that scanning (see Excluding Forcepoint files from antivirus scans). Please contact Technical Support for more information on enhancing performance.
