did you try what the previous post said, i.e. the $! which gives the system message?

you should also have
Code:
my $sock = new IO::Socket::INET(
   'PeerAddr' => 'xx.xx.xx.xx',
   'PeerPort' => 26637,
   'Proto' => 'tcp',
   reuse => 1,
);

here's why...
Code:
What exactly does SO_REUSEADDR do? 
  This socket option tells the kernel that even if this port is busy (in
  the TIME_WAIT state), go ahead and reuse it anyway.  If it is busy,
  but with another state, you will still get an address already in use
  error.  It is useful if your server has been shut down, and then
  restarted right away while sockets are still active on its port.  You
  should be aware that if any unexpected data comes in, it may confuse
  your server, but while this is possible, it is not likely.

also, you don't need the quotes on the LHS of a
Code:
=>

because
Code:
x=>y

is shorthand for
Code:
"x", y

LDAP_CONNECT(3) 							 1							   LDAP_CONNECT(3)

ldap_connect - Connect to an LDAP server

SYNOPSIS

       resource ldap_connect NULL ([string  $hostname], [int  $port = 389])

DESCRIPTION

	Establishes a connection to a LDAP server on a specified $hostname and $port.

PARAMETERS

	      o $hostname
		- If you are using OpenLDAP 2.x.x you can specify a URL instead of the hostname. To use LDAP with SSL, compile OpenLDAP 2.x.x with
		SSL support, configure PHP with SSL, and set this parameter as ldaps://hostname/.

	      o $port
		- The port to connect to. Not used when using URLs.

RETURN VALUES

	Returns a positive LDAP link identifier on success, or FALSE on error. When OpenLDAP 2.x.x is used, ldap_connect(3) will always  return  a
       resource  as it does not actually connect but just initializes the connecting parameters. The actual connect happens with the next calls to
       ldap_* funcs, usually with ldap_bind(3).

	If no arguments are specified then the link identifier of the already opened link will be returned.

EXAMPLES

       Example #1

	      Example of connecting to LDAP server.

	      <?php

	      // LDAP variables
	      $ldaphost = "ldap.example.com";  // your ldap servers
	      $ldapport = 389;		       // your ldap server's port number

	      // Connecting to LDAP
	      $ldapconn = ldap_connect($ldaphost, $ldapport)
			or die("Could not connect to $ldaphost");

	      ?>

       Example #2

	      Example of connecting securely to LDAP server.

	      <?php

	      // make sure your host is the correct one
	      // that you issued your secure certificate to
	      $ldaphost = "ldaps://ldap.example.com/";

	      // Connecting to LDAP
	      $ldapconn = ldap_connect($ldaphost)
			or die("Could not connect to {$ldaphost}");

	      ?>
