I've borrowed the code below from the Perl cookbook (Chap 17).

Started with TCP sockets (see links), but really want Unix domain (##URL REMOVED##) (as the clients/server will be on the same machine).

The INET version works fine, but converting the socket to Unix as shown means no input seems to arrive at the server.

Server (##URL REMOVED##)

use POSIX;
use IO::Socket;
use IO::Select;
use Socket;
use Fcntl;
use Tie::RefHash;
                                                                      
+          
$port = N;               # change this at will
                                                                      
+          
# Listen to port.
#$server = IO::Socket::INET->new(LocalPort => $port,
#                                Listen    => 10 )
#  or die "Can't make server socket: $@\n";
                                                                      
+          
unlink "/tmp/mysock";
$server = IO::Socket::UNIX->new(Local => "/tmp/mysock",
                                Type      => SOCK_STREAM,
                                Listen    => 5 )
    or die "Failed to make socket: $!";

Obviously I've obscured the actual machine ip/port.
