[WEB4LIB] CGI Script Question

Fri Jan 29 16:44:52 EST 1999

Using PERL the example shows the following:

Client-Side Sockets

use IO::Socket;
$sock = new IO::Socket::INET (PeerAddr => 'www.ora.com',
                              PeerPort => 80,
                              Proto    => 'tcp');
die "$!" unless $sock;

Server-Side Sockets

use IO::Socket;
$sock = new IO::Socket::INET (LocalAddr => 'maude.ora.com',
                              LocalPort => 8888,
                              Proto     => 'tcp',
                              Listen    =>5);

The client side example attempts to connect to PeerAddr over PeerPort using tcp.
The server side example provides a wrapper for creating the server socket.  The
parameters for the new socket object determine whether it is a server or client
socket.  Local provides the address and port to bind to the socket.  The Listen can
wait for an accept.  When the server receives a client request, it calls the accept
methon on the socket object.

This creates a new socket on which the rest of the communication can take place:
$new_sock = $sock->accept():

When communication is finished on both client and server sockets, they should be
destroyed with "close" other wise the socket will remain in use.

The command "send" writes data to a file handle so you could probably do something
like add in the line:

  $logonauth = "###-###-###";
  $authpass  = "XXXX";
  send($sock, $logonauth);
  send ($sock, $authpass);

I don't know if that will work but you may want to try it.  This is from a short
section in PERL IN A NUTSHELL book (about 10 pages) on sockets.  If you haven't used
perl with forms there are some very basic examples at

http://intelnt.library.appstate.edu/cs3490/

I know this is not a complete answer but maybe it well help with direction.
