PVS Troubleshooting

PVS server does not appear to be operational

  • Verify in the SecurityCenter GUI that the PVS server appears as “Unable to Connect” under “Status”.
  • SSH to the remote PVS host to make sure the underlying operating system is operational.
  • Confirm that the PVS is running (Linux example below):

    # service pvs status

    PVS is stopped
    PVS Proxy (pid 3142) is running
    #

  • If the PVS service is not running, start the service:

    # service pvs start
    Starting PVS Proxy                                         [  OK  ]
    Starting PVS                                               [  OK  ]
    #

Cannnot add a PVS server

  • Confirm that the PVS proxy is listening on the same port as is configured in SecurityCenter (port 8835 by default):

    # ss -pan | grep 8835
    tcp        0      0 0.0.0.0:8835    0.0.0.0:*     LISTEN      406/pvs

  • Check connectivity by telnetting from the SecurityCenter console yum into the PVS server on port 8835 (the pvs listening port). If successful, the response will include: Escape character is '^]'.

No vulnerabilities are being received from the PVS server

  • Ensure that the PVS service is running on the PVS host.
  • Ensure that the PVS is listed in SecurityCenter under “Resources” and “Passive Scanners” and that the status of the PVS is listed as “Working”. Click “Edit” to ensure that the IP address or hostname, port, username, password, and selected repositories for the PVS are all correct. Edit any incorrect entries to their correct state and click “Submit” to attempt to reinitialize the PVS’ scanning interface.

PVS plugins fail to update

  • Manually test a plugin update under “Plugins” with “Update Plugins”. If successful, the line “Passive Plugins Last Updated” will update to the current date and time.
  • Ensure that the SecurityCenter host is allowed outbound HTTPS connectivity to the PVS Plugin Update Site.
  • For all other PVS plugin update issues, contact Tenable Support at support@tenable.com.
