from dc i can ping the centos server. but from the centos server i cant ping the dc1.devlab.local. but i can ping the dc1 ip address? seem my centos can resolve the dns name?

the netstat -t command is on the dc1.devlab.local right? or is it on the centos terminal? when i type netstat nothing happen in centos? the netstat -t work on the dc1 but not the "i grep : 389" part

in my lab env i have a workstation also I downloaded putty to telnet to the dc1 . I get a error msg: Network error: Connection refused. from cmd using windows telnet: from pc1w7x64 telnet dc1.devlab.local 398 I get a blinking _ When i press enter i resume to c:\users\usr01>

I can telnet from Centos terminal too the DC fine. : telnet dc1.devlab.local 389 The script im using is this. <?php // using ldap bind $ldaphost = 'dc1.devlab.local'; $ldaprdn = 'uid=ldap,OU=testOU,DC=devlab,DC=local'; $ldappass = '123456ABCabc'; $ldapport = '389'; // connect to ldap server $ldapconn = ldap_connect($ldaphost, $ldapport) or die("Could not connect to LDAP server."); if ($ldapconn) { // binding to ldap server $ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass); // verify binding if ($ldapbind) { echo "LDAP bind successful..."; } else { echo "LDAP bind failed..."; } } ?>
