Changing Sensor Operation Without Web Console Access

Note

This applies to on-premise systems only.

Symptom

You are unable to access the Web Console, but need to de-activate Network Sensors in your environment.

Cause

There are many reasons this may occur, for example:

  • Blockage of HTTPS traffic by Genians or another security system
  • Failure of the Web Console to properly load

Resolution

Control Sensors through the Policy Server CLI

  • Use SSH on the Policy Sever as shown below, and access the shell:
genian> en

genian# @shell

Genians$
  • To STOP sensors, use command centerd -dfS [Sensor]
  • To stop one sensor, use the command referencing a single sensor IP: centerd -dfS 10.10.10.100
  • To stop multiple sensors, use the command referencing a multiple sensor IPs(up to 32) separated by comma: centerd -dfS 10.10.10.100,10.10.20.100
  • To stop all sensors, use the command referencing all sensors: centerd -dfS all
  • To START sensors, use command centerd -dfR [Sensor]
  • To start one sensor, use the command referencing a single sensor IP: centerd -dfR 10.10.10.100
  • To start multiple sensors, use the command referencing a multiple sensor IPs(up to 32) separated by comma: centerd -dfR 10.10.10.100,10.10.20.100
  • To start all sensors, use the command referencing all sensors: centerd -dfR all

Check Sensors Status through the Policy Server CLI

  • Type exit to exit the shell mode and re-authenticate.
  • To show sensors, use command show sensor [option]
  • Use the available options to filter results by sensor status: all, active, passive, unknown
