Open Ports on Agent Host
The agent process listens for commands on two ports 127.0.0.1:2144 and 127.0.0.1:32000 that are
congurable. These ports might be arbitrarily assigned, and so, the exact port number might vary. The agent
does not open ports on external interfaces.
Table 3‑3. Minimum Required Ports
Port Protocol Direction Comments
443 TCP Outgoing Used by the agent for outgoing connections over HTTP, TCP, or ICMP.
2144 TCP Listening Internal Only. Congurable. Used for inter-process communication between
the agent and the command line that loads and congures it. The agent process
listens on this port.
N The port number is assigned arbitrarily and might dier.
32000 TCP Listening Internal Only. Congurable. Used for inter-process communication between
the agent and the command line that loads and congures it. The agent process
listens on this port.
N The port number is assigned arbitrarily and might dier.
Revoking an Agent
If for any reason you need to revoke an agent, for example when a system with a running agent is
compromised, you can delete the agent resource from the system. Any subsequent request will fail
verication.
Use the vRealize Operations Manager user interface to revoke the agent certicate by removing the agent
resource. For more information, see “Removing the Agent Resource,” on page 38.
When the system is secured again, you can reinstate the agent. For more information, see “Reinstate an
Agent Resource,” on page 38.
