Firewalls and Ports

Firewalls and Ports

All of the ports used by the Chef server are TCP ports. Refer to the operating system’s manual or site systems administrators for instructions on how to enable changes to ports, if necessary.

All services must be listening on the appropriate ports. Most monitoring systems provide a means of testing whether a given port is accepting connections and service-specific tools may also be available. In addition, the generic system tool Telnet can also be used to initiate the connection:

$ telnet HOST_NAME PORT

Note

An “external” port is external from the perspective of a workstation (such as knife), a machine (the chef-client), or any other user that accesses the Chef server via the Chef server API.
