Agent and Device Ports

Although custom ports can be set in the agent's configuration files, the following are the default and recommended ports:

Change Tracker Console​

  • Port: 443 OR Custom
  • HTTPS Communication to the Change Tracker Console is by default HTTPS onport 443. This can be adjusted within IIS if other ports are deemed more suitable.

Change Tracker Agents – Windows & Linux​

  • Port: 443 OR Custom
  • HTTPS Communication between Change Tracker and the agent is controlled by the agent's HUBURL, defined during installation. The HUBURL will resemble https://MY_CT_SERVER/api/. The communication is one-way and will always be initiated by the agent.

Change Tracker - Agentless Linux​

  • Port: 22
  • TCP/SSH One-way communication is initiated from the Change Tracker Proxy Agent (The proxy agent is collocated with Change Tracker but can be installed on a separate system).

Change Tracker - Agentless Windows​

  • Port: 445
  • One-way communication is initiated from the Change Tracker Proxy Agent (The proxy agent is collocated with Change Tracker but can be installed on a separate system) to the Remote Registry Service on the Windows devices.
