[Forcepoint] Administrator Immediately Logged Out when Using SMC Web Access

Problem

On SMC 6.6 version, you can enable the SMC Web Access feature to start and run the Management Client in a web browser.

If this feature is enabled, some deployments may experience an issue where you are immediately logged out after logging into Web Access with the Linux platform administrator credentials.

Resolution

Web Access has Linux package dependencies, and the platform may be missing a required package, which causes this log in issue. This is more common on minimal CentOS installations.

Use the following commands to install the required packages. Perform these commands either as root or using sudo (RPM to use is xorg-x11-server-xvfb-x):

• CentOS and Red Hat Enterprise Linux:

yum install Xvfb libXrender libXtst libXext libXi gtk2

• Ubuntu:

apt-get install xvfb libxrender1 libxext6 libxtst6 libxi6 libgtk2.0-0

• SUSE Linux Enterprise:

zypper install xorg-x11-server-extra xorg-x11-libXrender xorg-x11-libXext

Note Suse Linux Enterprise does not provide xvfb-run script that starts the Xvfb binary, requiring this script to be manually copied from another distribution. The xvfb-run script attached to this article can be downloaded and placed into /usr/bin/.

Note TTF font packages dejavu-fonts-common and dejavu-sans-fonts might also need to installed. Lack of these packages may not cause login to fail, but may cause other random issues. To install these packages on CentOS server use below command:

yum -y install dejavu-fonts-common dejavu-sans-fonts
