Preparing the network environment

The network environment involves the network infrastructure including ports, email administration, and replay server.

About this task

Before you deploy HCL Discover, verify that your network infrastructure is configured to send data to the HCL Discover Network Capture Application in a method that is suitable for capture.

Preparing the network environment involves opening ports, configuring email requirements and configuring the replay service.

To prepare the network environment:

Procedure

  1. Configure firewall openings for bidirectional communication.

    See Opening Ports for a description of the ports to open.

    Table 1. Opening Ports
    Port 2 way? Origination Destination Change port? Description
    22 Y

    HCL Discover server or administrator's desktop

    		HCL Discover Network Capture Application N

    Remote Secure Shell
    25 Y

    HCL Discover Server

    		SMTP Mail system N

    Sends mail via SMTP from components of HCL Discover to the mail server
    80 or 443 Y

    Portal thin client (Browser)

    		Portal Server (HCL Discover server) N

    Thin Client Note: To enable effective replay, the Replay Server might require access to static content stored on the origin server. Typically, this access occurs over ports 80 or 443. .
    1433 Y

    Report Server

    		 Remote SQL Server Y

    Needed only if Reporting DB is MSSQL and Report Server is on a platform other than MSSQL server
    1966 Y

    Capture Filters (Native and DNCA)

    		 HCL Discover server Y

    Captured data stream
    5597 Y

    Report Server

    		 Canister Y

    Communications between Portal and ctree session database on Canister.
    8080 or 8443 Y

    HCL Discover server or administrator's desktop

    		DNCA Y

    DNCA Status and configuration program
    19000 Y

    Search Server

    		 HCL Discover Server N

    Searches and retrieves sessions via TCP/IP
    20000 Y

    Portal Server, HCL Discover Management System (on all servers except DNCA server)

    		HCL Discover Management System (on all servers except DNCA server) N

    Communication for retrieving and sending configurations of HCL Discover servers, components, and databases
    23000 Y

    Portal

    		HCL Discover databases N

    HCL Discover Data Service
    38000

    For advanced configuration of your replay server, contact your account representative or Professional Services.
  2. Configure email requirements.

    Most organizations configure email systems to accept email at a particular machine, such as smtp.company.com or mail1.company.com.

    To support HCL Discover email requirements:

    1. Configure the SMTP receiving computer to accept mail for the HCL Discover server.
    2. Verify that the HCL Discover server can resolve the SMTP server name and that the SMTP server can be pinged from the HCL Discover server.

      The SMTP port between the HCL Discover server and the SMTP server must be opened through any intervening firewalls.

      Note: It is recommended that you identify a HCL Discover administrator with a valid, reachable email address before you begin the installation process.
  3. Configure the replay service

    The replay server manages replay of sessions.

    You can configure the replay server to access replay of sessions or disable interactive services detection.

    1. Enable Replay server access to the web application
    2. Disable Interactive Services Detection

      When the WebKit/Chrome renderer is enabled for the Replay Server, it conflicts with the Interactive Services Detection service on the hosting machine. This service must be disabled.

      The Replay Server is a HCL Discover component used to render sessions for replay through Browser Based Replay. It is typically hosted on the Portal Server.

      The WebKit/Chrome renderer is used to render for replay sessions initiated from mobile devices.

      Note: The Interactive Services Detection service is automatically disabled by the HCL Discover Installer or Upgrader during normal operations. Afterward, the service can be disabled through the Windows Services control panel on the server hosting the Replay Server.
      Note: If your environment utilizes multiple Replay Servers, this service must be disabled on each Replay Server in your environment.

      Alternatively, you may disable this mobile-based renderer for individual groups through the Portal Management page.
