       ncaport.conf - ncaport configuration file


       The  ncaport.conf  file	is  used to configure the IP addresses and ports that the Solaris
       Network Cache and Acceleration (NCA) kernel module services. The file contains two fields,
       key  and value, in the format of ncaport=ipaddress/port. IPv4 addresses must be in the dot
       notation d.d.d.d. IPv6 addresses must be in one	of  the  three	conventional  forms  (see
       inet_pton(3SOCKET)).  If  an  asterisk (*) is used for an IP address, it is interpreted as
       INADDR_ANY, which matches any IP address.

       A web server uses the environment variable LD_PRELOAD and the  ncaport.conf  configuration
       file  to  convert an AF_INET socket to an AF_NCA socket. LD_PRELOAD enables the NCA socket
       utility library to be loaded before libsocket.so.1. See the ncad_addr(4) for details. When
       a  web server issues the bind(3SOCKET) system call, it is intercepted by the interposition
       library ncad_addr.so. If the bind address is in the ncaport.conf file, the AF_INET  socket
       is converted to a AF_NCA socket.

       Example 1 Sample ncaport.conf File

       The following is a sample ncaport.conf file:

	 # NCA Kernel Module Port Configuration File

       nca(1), bind(3SOCKET), inet_pton(3SOCKET), ncad_addr(4), attributes(5)

       For  those  web servers that use AF_NCA sockets, the NCA port configuration described here
       has no effect.

       NCA does not currently support IPv6. Any IPv6  addresses  in  the  file	ncaport.conf  are
