Distributed file system (DFS), which centralizes the file system utilities
Network information services plus (NIS+) including NFS
Name service switch file
The Solaris 7 operating environment supports the network information service (NIS), the SunOS release 4 name service, and the network information services plus (NIS+), an enterprise-naming service of heterogenous distributed systems. See "NIS+" for the nature of NIS+ support available in the Solaris 7 operating environment.
NIS+ provides improved security, a more detailed model for objects in the name space, and faster updates than NIS.
The NIS+ programmer interfaces are documented in section 3N of the man Pages(3): Library Routines.
The nsswitch.conf file simplifies name service administration. Applications can use this file to select a name service. This information no longer needs to be hard-coded into the service. See the nsswitch.conf(4) man page for more information on the format of this file.
See pfmod(7M), bufmod(7M), and dlpi(7P)
Sockets are supported in the Solaris 7 operating environment. Unlike the SunOS release 4 software, sockets are no longer implemented completely in the kernel. They are now in a library, libsocket, implemented on STREAMS.
