Hm, I don't think so. The connection is made by a so called XMLSocket in Flash, it's a socket that sends and receives string data (XML mainly, but any string is fine, as long as you don't let Flash parse it, but here it is automated because the request gets out before you actually use your socket connection).

So, what I have is

Code:

open POLICYFILE, "<$filePath" or die "Can't open '$filePath': $!\n";
$content = <POLICYFILE>;
close POLICYFILE;
...
print CONNSOCK $content;
print CONNSOCK $NULLBYTE;
close CONNSOCK;

in the standalone script versus

Code:

open POLICYFILE, "<$filePath" or die "Can't open '$filePath': $!\n";
$content = <POLICYFILE>;
close POLICYFILE;
...
print STDOUT $content;

in the xinetd script.

I guess that xinetd is supposed to push the output into the socket and add the terminating NULL byte. I don't know how xinetd works, but I've read that you just have to give your output into STDOUT when you're doing a xinetd service, so I guess this is the way to do it.

However what xinetd does after that is beyond me.

     cate the error.

ERRORS

     The call succeeds unless:

     [EBADF]		Socket is not a valid descriptor.

     [EINVAL]		The how argument is invalid.

     [ENOTCONN] 	The specified socket is not connected.

     [ENOTSOCK] 	Socket is a file, not a socket.
