pmap_nis State Engine

The pmap_nis state engine is used for the portmap protocol used by NIS services. It monitors NIS portmap requests and responses and builds a table of host/port to NIS service mappings. The ypserv service is typically the only service definition that uses the pmap_nis state engine.

The discriminator for the pmap_nis state engine is the RPC program number of the service. This is always 100004, which is the RPC program number for NIS.

The pmap_nis state engine has the following parameters:

• Response timeout in seconds - Specifies the time to wait for NIS portmap responses (default = 60 seconds)

• Lifetime of NIS portmap mapping entries in seconds - -1 specifies an infinite lifetime. Because NIS clients cache portmap information indefinitely at boot time, this value is normally set to -1 (default = -1).
