SecurityCenter Troubleshooting

SecurityCenter 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 SecurityCenter 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 SecurityCenter host:

    # df

    Filesystem                         1K-blocks     Used       Available     Use%     Mounted on
    /dev/mapper/VolGroup00-LogVol00    8506784       8506784    0             100%     /
    /dev/sda1                          101086        24455      71412         26%      /boot
    tmpfs                              1037732       0          1037732       0%       /dev/shm

  4. If there is not enough drive space, recover sufficient space and restart the SecurityCenter service:

    # df

    Filesystem                         1K-blocks     Used       Available    Use%     Mounted on
    /dev/mapper/VolGroup00-LogVol00    8506784       6816420    1251276      85%      /
    /dev/sda1                          101086        24455      71412        26%      /boot
    tmpfs                              1037732       0          1037732      0%       /dev/shm

    # service SecurityCenter restart

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.
