NAME
ncad_addr - name of the Solaris Network Cache and Accelerator (NCA) socket utility library SYNOPSIS
/usr/lib/ncad_addr.so DESCRIPTION
ncad_addr.so is the Solaris Network Cache and Accelerator (NCA) socket utility library. Use this library with a web server to avoid support for the PF_NCA family type socket. The web server can take advantage of NCA functionality. Interpose the ncad_addr interfaces before the interfaces in libsocket by setting the environment variable LD_PRELOAD to ncad_addr.so so that it is preloaded before libsocket.so.1. The ncad_addr.so interfaces will be interposed only if NCA is enabled. See ncakmod(1). EXAMPLES
Example 1: Interposing ncad_addr Using Bourne shell syntax as an example, set LD_PRELOAD as shown below to interpose the ncad_addr socket utility libary: LD_PRELOAD=/usr/lib/ncad_addr.so /usr/bin/httpd FILES

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. SunOS 5.10 30 Jul 2001 ncaport.conf(4)
