I don't think I can tell you anything you don't already know, but let's review the situation.

You want a client/server architecture: a server accepts incoming connections from the clients, and stores the information they submit when they connect. The server can be a simple program which merely accepts incoming connections, reads whatever the clients submit, and stores it to a file, then disconnects. Similarly, the clients can simply open a connection, dump a report, and disconnect.

The sample code you find in the perlipc manual page can do this, but if you have performance demands, it might not be enough. Then it's probably better to go look for a server architecture which is designed for heavy concurrency. Apache has a good reputation in this regard, although you can look for others, too. You'll just need to figure out a way to make it do what you want. A simple CGI script is a good way to make Apache do something different than just serve up static web pages.

Are you following so far? So my suggestions at this point would be to test the "simple forking server" you find in man perlipc and measure whether it performs well enough. If it doesn't, see if you can make Apache suit your needs.

tcp-env

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME

       tcp-env - set up TCP-related environment variables

SYNOPSIS

       tcp-env [ -rR ] [ -ttimeout ] program [ arg ...  ]

DESCRIPTION

       The  input  for  tcp-env  must be a TCP connection.  tcp-env finds out information about that connection, puts the information into several
       environment variables as described in tcp-environ(5), and runs program with the given arguments.

       Usually tcp-env is run from inetd.  It might instead be run from another server that already sets up the right  environment  variables;  if
       PROTO  is  set  to  TCP  when  tcp-env  is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
       whether the input is a TCP connection.

OPTIONS

       -r     (Default.)  Attempt to obtain TCPREMOTEINFO from the remote host.

       -R     Do not attempt to obtain TCPREMOTEINFO from the remote host.

       -ttimeout
              Give up on the TCPREMOTEINFO connection attempt after timeout seconds.  Default: 30.

SEE ALSO

       tcp-environ(5), inetd(8)

                                                                                                                                        tcp-env(1)
