SecurityCenter Troubleshooting

SecurityCenter does not appear to be operational

  • Close and reopen the web browser if a login page does not appear.
  • 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

  • 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

  • If drive space has become exhausted for any reason, sufficient space must be recovered and the SecurityCenter service must be restarted for SecurityCenter to become operational:

    # 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

    Shutting down SecurityCenter services:                     [  OK  ]
    Starting SecurityCenter services:                          [  OK  ]
    #

Invalid license error

  • If you receive an invalid license error while attempting to log in as a Security Manager or lower, an administrator 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. Licenses are obtained from Tenable and copied to the daemons directory as the “tns” user.

Reporting does not work

  • Check your Java version. Only OpenJDK and Oracle JRE are supported. The existence of another type of Java on the system will likely break reporting.
