You can configure the vCenter Hyperic agent to initiate all communications with the server. You configure unidirectional communications at first startup. Unidirectional communications are always via SSL.

As an alternative to this procedure, you can specify unidirectional communications via the agent prompt that appears at startup.


Stop the agent.


Remove the agent's \data directory.

If you remove the \data directory, at next startup, the agent checks its file for the startup settings that it requires to connect to the server. If the properties file does not contain the startup settings, it opens a shell to prompt for them.


In the file, set setagent.setup.unidirectional=yes, and start the agent.


In the user interface, on the Inventory tab of the platform, navigate to Type & Network Properties and click Edit.

The Agent Connection menu shows the currently selected port for bidirectional communications. For example,, where is the IP address of the platform, and 2144 is the bidirectional port number previously used.


Expand the menu and select the entry that shows the same IP address, and -1 as the port number.

For example,

The agent uses unidirectional communication with the server.
