Installing the crawler agent

The crawler is the name of the discovery and fingerprinting agent. It is selected by default when you install the Data Security Management Server or supplemental Data Security servers.

You can deploy additional crawlers in your network if you desire. When you set up a fingerprint task, you indicate which crawler should perform the scan. Websense recommends that you use the crawler that is located closest to the data you are scanning.

You can view the status of your crawlers in the TRITON - Data Security user interface. Go to Settings > Deployment > System Modules, select the crawler and click Edit.

Operating system support

Supplemental Data Security servers must be running on one of the following operating system environments:

Windows Server 2003 (32-bit) Standard or Enterprise R2 SP2

Windows Server 2008 (64-bit) Standard or Enterprise R2

Installing the crawler agent

Download the Websense installer (WebsenseTRITON77Setup.exe) from mywebsense.com.

Launch the installer.

Accept the license agreement.

Select Custom.

Click the Install link for Data Security.

On the Welcome screen, click Next to begin the installation.

In the Destination Folder screen, specify the folder into which to install the agent.

The default destination is C:\Program Files or Program Files (x86)\Websense\Data Security. If you have a larger drive, it is used instead. Large removable drives may be detected by the system as a local drive and used as the default. Do not install on removable media.


	Important The full installation path must use only ASCII characters. Do not use extended ASCII or double-byte characters.


	Note Regardless of what drive you specify, you must have a minimum of 0.5 GB of free disk space on the C: drive. This is because Data Security installs components into the Windows "inetpub" folder on C:.

On the Select Components screen, select Crawler agent and then Entire feature will be installed on local hard drive. If this is a stand-alone installation, deselect all other options, including Data Security Server.

In the Server Access screen, select the IP address to identify this machine to other Websense components.

The following message may appear:

Data Security Discovery Agent works with a specific version of WinPcap.
The installation has detected that your WinPcap version is <version>
In order to proceed with this installation, WinPcap version 4.0.0.1040 needs to be installed and will replace yours.
Click Yes to proceed or Click No to preserve your WinPcap version and deselect the Discovery Agent Feature to continue with the installation.

"Discovery Agent" refers to the crawler agent. The particular version of WinPcap mentioned in this message must be in place to install Crawler Agent. Note that after installation of the crawler agent you can install a different version of WinPcap. The crawler agent should continue to work properly.

10.

In the Register with the Data Security Server screen specify the path and log on credentials for the Data Security server to which this agent will connect. This could be the TRITON management server or a secondary Data Security server.

FQDN is the fully-qualified domain name of a machine.

11.

In the Local Administrator screen, enter a user name and password as instructed on-screen. The server/host name portion of the user name cannot exceed 15 characters. If you are installing Data Security v7.7.0, this password cannot exceed 19 characters. If you are installing version 7.7.2 or beyond, password length doesn't matter.

If you installed a Lotus Notes client on this machine so you can perform fingerprinting and discovery on a Lotus Domino server, the Lotus Domino Connections screen appears.

If you plan to perform fingerprinting or discovery on your Domino server, complete the information on this page.

Important

Before you complete the information on this screen, make sure that you:

Create at least one user account with administrator privileges for the Domino environment. (Read permissions are not sufficient.)

Be sure that the Lotus Notes installation is done for "Anyone who uses this computer."

Connect to the Lotus Domino server from the Lotus Notes client.

On the Lotus Domino Connections page, select the check box labeled Use this machine to scan Lotus Domino servers.

In the User ID file field, browse to one of the authorized administrator users, then navigate to the user's user.id file.


	Note Select a user that has permission to access all folders and Notes Storage Format (NSF) files of interest, otherwise certain items may not be scanned.

In the Password field, enter the password for the authorized administrator user.
