NCAPORT.CONF(4) File Formats and Configurations NCAPORT.CONF(4)


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(3C)). 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(3C), 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.
