nis State Engine

The nis state engine is used to define services that are NIS UDP sessions. The predefined service ypserv uses the nis state engine and is normally the only service definition that uses this state engine.

The discriminator for this state engine is the RPC program number of the service. Normally, this is always 100004, the RPC program number for NIS.

The nis state engine has the following parameters:

• Response timeout in seconds - Specifies the time to wait for NIS responses. -1 specifies the state engine will wait forever (default = 60 seconds).

• Number of expected responses per request - Typically 1, because an NIS server sends only a single response to a request (default = 1).

• Flag value - If this value is set to 2, then the system accepts NIS responses from a different port than the NIS request port. This case occurs when an NIS server is responding to name lookups that is mapping to DNS entries (default = 2).
