NAME
     ncaport.conf - ncaport configuration file

SYNOPSIS
     /etc/nca/ncaport.conf

DESCRIPTION
     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.

EXAMPLES
     Example 1: Sample ncaport.conf File

     The following is a sample ncaport.conf file:

     #
     # NCA Kernel Module Port Configuration File
     #
     ncaport=1080:0:0:0:8:800:200C:417A/100
     ncaport=192.168.84.71/80
     ncaport=*/9000

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

NOTES
     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 ignored.
