The hello command is used to obtain a greeting element from our server and may be used to keep your connection with our EPP server open.  Sending an EPP hello command every 59 minutes will keep your connection with our EPP server open.

A <greeting> element is sent by the server to the client and specifies the object services that the server provides, it is sent in response to a <hello> element and also on connection to the server.

An EPP <hello> element is an empty element with no child elements.

An EPP <greeting> from Nominet's EPP server contains the following elements

• An <svID> element containing the name of the server
• An <svDate> element containing the server's current date and time in UTC.
• An <svcMenu> element that identifies the services supported by the server. This contains the following sub elements
  
  • A <version> element with content 1.0 that identifies the protocol version supported by the server.
    
  • A <lang> element with content 'en' which gives the language known by the server, 'en'.
  • <objURI> elements that contain the namespace URIs for the objects that can be manipulated in the session.
  • An optional <svcExtension> element that identifies the service extensions supported by the server. This contains the following sub elements
    • <extURI> elements that contain the namespace extension URIs for objects that can be manipulated during the session.
• A <dcp> (data collection policy) element that contains child elements that describe the server's privacy policy for data collection and management. This contains the following sub-elements
  • An <access> element with a child element of <all/> to show that access is given to the client to all data.
  • A <statement> element with the following sub-elements:
    • A <purpose> sub-element with <admin/> and <prov/> child elements to define that we collect data for administrative and technical support of the provisioning system and to identify objects and inter-object relationships.
    • A <recipient> sub-element with a child element of <ours/> which declares that Nominet, the server operator, are the recipients of the collected data.
    • A <retention> sub element with an <indefinite/> child element which declares that we retain the data indefinitely.

RFC 5730 shows the full definition of the <greeting> element.
