Pre-installation requirements

Before installing the Forcepoint DLP Protector software, you have to ensure the requirements are met.

• Forcepoint DLP Protector software package is supported on CentOS 7.6 or CentOS 7.9, or on RHEL 7.5, RHEL 7.6, RHEL 7.7, RHEL 7.8, or RHEL 7.9.
• For software package deployment, verify that the outputs of the two commands match:

  "hostname -f": --fqdn, --long long host name (FQDN)

  "hostname -s": --short short host name

  If the outputs match, you can continue the installation.

  If the outputs do not match, the fully-qualified domain name (FQDN) (long) should be changed to match the short hostname. To change the FQDN you must open the hosts file located in /etc/hosts as root and add the following entry to the hosts file:

  <Protector IP address> <New Hostname> (match to the short hostname, hostname -s)

  

• At least two network interface cards are required.
• For hardware requirements, see Protector Hardware Requirements.
• The file system where /opt directory resides must have a minimum of 45GB disk space.
• SELinux must be disabled before the software protector installation.
• The installation will check whether firewall or NetworkManager are running and disable them if they are running.
