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.
