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
