General Tenable Security Center Troubleshooting

Tenable Security Center does not appear to be operational

  1. If a login page does not appear, close and reopen the web browser.

  2. Ensure that the remote httpd service is running on the Tenable Security Center host:

    # ps ax | grep httpd

    1990 ?        Ss     0:01 /opt/sc/support/bin/httpd -k start

  3. Ensure that sufficient drive space exists on the Tenable Security Center host:

    # df

    /dev/mapper/VolGroup00-LogVol00    8506784       8506784    0             100%     /
    /dev/sda1                          101086        24455      71412         26%      /boot
    tmpfs                              1037732       0          1037732       0%       /dev/shm

Invalid license error

If you receive an invalid license error while attempting to log in as a security manager or lower organizational user, an administrator user must log in and upload a new valid license key. A user with access to the host OS and valid permissions can also check that an up-to-date license exists in /opt/sc/daemons. Obtain a license from Tenable and copy it to the daemons directory as the tns user.

Reporting does not work

Check your Java version. The system only supports OpenJDK and Oracle JRE. The existence of another type of Java on the system will likely break reporting.
