INADDR_ANY opposite

Hello, is there some way to obtain system's IP adresses to bind socket to every of them separately instead od INADDR_ANY? OR If there is some way to get server's IP to which client has connected, for example: server_app - bind to listen on INADDR_ANY, gets connected client to 1.2.3.4,...

UDP server socket inaddr_any - How to get the real IP

Hello ! I seem to have the same problem as in https://www.unix.com/ip-networking/91203-inaddr_any-opposite.html#post302262417 But I can't find a solution. I have a UDP server socket bound to 0.0.0.0. The server hosts the addresses IP1, IP2 and IP3. I get an incoming request to IP1. I use...

ncaport.conf

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.
