In this case, installation is a two-part process:
|1.||Install Websense software.|
On the designated machine or machines, install Websense components. See theÂ Installation GuideÂ for instructions.Websense Filtering Service must be installed on its machine before installing theÂ Websense Squid plug-in on the Squid machine. Filtering Service must be installed as integrated with Squid Web Proxy Cache.Install Websense Network Agent to filter non-HTTP(S)/FTP traffic (e.g., instantÂ messaging, streaming media, peer-to-peer, and so forth) which is not handled by Squid Web Proxy Cache. If Network Agent is installed on a separate machine, it must be connected to a bi-directional span port on a network switch (see theÂ Deployment GuideÂ for Websense Web Security Solutions for information about where to place Network Agent in your network). If Network Agent is installed on the Squid machine, connecting to a span port is not necessary.
|2.||Install the Websense Squid plug-in on the Squid machine.|
Run the Websense installer on the Squid machine and choose to install the plug-inÂ only. SeeInstalling the Squid plug-in, below.Installing the Squid plug-inThe Squid plug-in is installed on the Squid machine to allow Websense FilteringÂ Service and Squid software to communicate.
|NoteÂ The Squid plug-in is supported only on Linux.|
If Filtering Service is installed on a separate machine from the Squid machine, it mustÂ be installed before you install the Squid plug-in. When it is installed, Filtering Service must be installed as integrated with Squid Web Proxy Cache. You must specify the location of Filtering Service when installing the Squid plug-in, otherwise the installer will not proceed.When installing the Squid plug-in, the installer checks for Squid Web Proxy Cache onÂ the installation machine. If Squid Web Proxy Cache is detected, the installer continues.If Squid Web Proxy Cache is not detected, installation of the Squid plug-in cannotÂ proceed.
|NoteÂ The following instructions are a supplement to the fullÂ instructions in theÂ Installation Guide. These instructions cover only those installer screens involved in installing the Websense Squid plug-in. Refer to theÂ Installation GuideÂ for full instructions on using the installer. TheIInstallationÂ GuideÂ refers you to this guide for instructions specific to integration with Squid Web Proxy Cache.|
The Websense installer is used to install the Websense Squid plug-in on the SquidÂ machine. The following procedure is performed on the Squid machine.
|NoteÂ Websense Filtering Service must be installed on itsÂ machine before installing the Squid plug-in on this machine.|
|ImportantÂ Make sureÂ visible_hostnameÂ is set in the squid.conf fileÂ beforeinstalling the Squid plug-in. See your Squid documentation for instructions.|
|1.||Download or copy the Websense installer to this machine.|
See theÂ Installation GuideÂ for instructions on downloading the installer.
|2.||Close all applications and stop any antivirus software.|
|3.||Start the Websense installer.|
See theÂ Installation GuideÂ for instructions on starting the installer.
|NotesThese instructions refer to GUI installer screens. There areÂ GUI and command-line versions of the Websense installer for Linux. In the command-line version, prompts are displayed that correspond to each GUI screen. Instructions for a screen also apply to the corresponding command-line prompt. The main difference is how options are selected. Rather than clicking items in a screen, you will enter menu-item numbers or characters.To cancel the command-line installer, press Ctrl-C.Â However, doÂ notcancel the installer, after theÂ Pre-Installation SummaryÂ screen, as it is installing components. In this case allow the installation to complete and then uninstall the components you did not want to install.|
|4.||On theÂ IntroductionÂ screen, clickÂ Next.|
|5.||On theÂ Subscription AgreementÂ screen, choose to accept the terms of the agreement and then clickÂ Next.|
|6.||On theÂ Installation TypeÂ screen, selectÂ CustomÂ and then clickÂ Next.|
|7.||On theÂ Custom InstallationÂ screen, selectÂ Filtering Plug-inÂ and then click Next.|
|8.||On theÂ Filtering Service CommunicationÂ screen, enter the IP address of the machine on which Filtering Service is installed and the port Filtering Service uses to communicate with integration products and Network Agent (default is 15868). Then clickÂ Next.|
The port used by Filtering Service to communicate with integration products andÂ Network Agent must be in the range 1024-65535. Filtering Service may have been automatically configured to use a port other than the default 15868. When Filtering Service was installed, if the installation program found the default port to be in use, it was automatically incremented until a free port is found. To determine what port is used by Filtering Service, check theÂ eimserver.iniÂ fileâ€”located inÂ C:\Program Files\Websense\binÂ (Windows) orÂ /opt/Websense/binÂ (Linux)â€”on the Filtering Service machine. In this file, look for theÂ WebsenseServerPortÂ value.
|ImportantÂ Do not modify theÂ eimserver.iniÂ file.|
|9.||On theÂ Select IntegrationÂ screen, selectÂ Squid Web Proxy Cache.|
|10.||On theÂ Squid ConfigurationÂ screen, enter paths to the squid.conf and squid executable files, and then clickÂ Next.|
The installation program will verify the path to squid.conf. A default path isÂ automatically entered. Enter a different path if necessary or clickÂ BrowseÂ to navigate to the location. This path must be verified for the installation to continue. (Note: the path must include the file name.)Additionally, you must provide the path to the Squid executable so the installationÂ program can shut it down to continue the installation.
|NoteÂ The installer will automatically start Squid Web ProxyÂ Cache once installation is complete. Verify it is running after installation is complete (Step 15 below).|
|11.||On theÂ Installation DirectoryÂ screen, accept the default installation path, or clickÂ ChooseÂ to specify another path, and then click Next.|
|12.||On theÂ Pre-Installation SummaryÂ screen, verify the information shown.|
Filtering Plug-inÂ should be listed as the only component to be installed.
|13.||ClickÂ NextÂ to start the installation. AnÂ InstallingÂ progress screen is displayed. Wait for the installation to complete.|
|14.||On theÂ Installation CompleteÂ screen, clickÂ Done.|
|15.||Start Squid Web Proxy Cache if necessary.|
The installer attempts to start Squid Web Proxy Cache once installation isÂ complete. In some cases, it must be manually started:
|a.||Verify Squid Web Proxy Cache is running, for example, by using theÂ commandÂ ps -ef | grep squid.|
|b.||If it is not running, start it.|
See Squid documentation or support resources for the start commandÂ appropriate to your installation of Squid Web Proxy Cache.
|16.||If you stopped antivirus software on this machine, restart it now.|
