Unable to get secure key from agent

Control Compliance Suite Standards Server Control Compliance Suite


Our CCS installation (12.5.2) has issues fetching the secure key from agents.




This has been found to be caused by a firewall, such as a local firewall on a Unix asset. 

For example, iptables or nftables running on a Linux server.


Create a rule on the firewall(s) to allow the communication with the agent to go through. 

Ports used by the Agents

5601 - Windows Agents
5600 - Unix Agents
5599 - Used for APU/ACU jobs to update the Agents.

Additional Information

For Agent based troubleshooting take note of what will get logged in the Agent log file, when an incoming connection is made outside of CCS.
