[resolved] Can I force a TCP port to close

i have recently uninsalled openldap, and reinstalled it.

I noticed that I could not start slapd because it said it address already in use...

Code:

[root@box openldap]# netstat -a |grep ldap

tcp        0      0 *:ldap                      *:*                        LISTEN

tcp        0      0 *:ldaps                    *:*                        LISTEN

ldap is not running.... ps aux shows no sign of ldap or slapd.
neither does top..

why is this port still open, and can i close it without restarting...?

Add the -p flag to netstat to see what process is using that port.

ha... Thank you very much

Turns out our mail server (CommuniGate) is doing ldap... i dont really trust it to do that. I'll be disabling this...
