Before Starting HP WBEM Services
For HP WBEM Services to work, these things must be present:
• Configured ports:
HP WBEM Services supports only ports 5988 (wbem_http) and 5989
(wbem_https). These two ports are specified by the Distributed
Management Task Force and are registered with IANA (Internet
Assigned Numbers Authority at http://www.iana.org).
NOTE Hewlett-Packard supports only these two port configurations: HTTP
on port 5988, and HTTPS on port 5989.
By default, HP WBEM Services HTTP server listens for SSL (Secure
Sockets Layer) encrypted communications on the HTTPS (secure)
port, 5989. If you are sure your environment is secure, you could set
the configuration so the server will listen at the HTTP (not SSL)
port, 5988. See Chapter 6, Security Considerations.
When HP WBEM Services receives an HTTP request over the
configured port, it checks user authentication, parses the request,
looks up the resource, and contacts the registered provider if
applicable. The provider sends a response to HP WBEM Services,
and HP WBEM Services sends it back to the client through this port.
• HP WBEM Services infrastructure:
See the Release Notes for specific information about installing your
version of HP WBEM Services. The release notes can be viewed or
printed from http://www.docs.hp.com -> Network and System
Management.
NOTE If you already have HP WBEM Services installed, check your release
notes before uninstalling it or re-installing it. You could remove all
the files associated with HP WBEM Services and make all your
providers unavailable.
