Hi all.

I am in the process of writing a perl based server for a professor of mine ( non-homework ) and I need a little help with some of the design aspects. Please see below for details:

Homework server:

• Function: Allow students to use a perl client to connect to and submit assignments to the instructor remotely.
  
  
• Requirement: Each student must have a unique id / password combination and a personal folder for their assignments.
  
  

Here is the code so far:

# Perl client
#!/usr/bin/perl -w

use strict;
use IO::Socket::INET;

local $| = 1;
my $host = '127.0.0.1';
my $port = 8500;

my $client = new IO::Socket::INET(

   PeerAddr  => $host,
   PeerPort  => $port,
   Proto     => 'tcp',
   Type      => SOCK_STREAM,

   ) or die "Couldn't create client : $!\n";
[download]

#Perl server
#!/usr/bin/perl -w

use strict;
use IO::Socket::INET;

local $| = 1;
my $response;
my $port = 8500;
my $client;
my $server = new IO::Socket::INET(

             LocalPort => $port,
             Type      => SOCK_STREAM,
             Listen    => 5,
             Proto     => 'tcp',
             Reuse     => 1,


  ) or die "Couldn't construct server on port: $port : $!\n";

$client = $server->accept();
$response = <$client>;
chomp $response;
[download]

I don't have access to a database ( at work ) yet so I was considering hard coding the id / pw combinations as constants in the server.pl file. I could fortify this application if I were to write it as a CGI program ( setting maximum uploads, etc. ) in order to guard against DOS attacks.

Any help would be greatly appreciated,
I'll post the completed code ( both client and server ) when it has been completed.

Thanks,
-Katie.
