I am currently pen-testing a remote website (its mine)

I would like to know if its possible to test if the web-server is running LDAP server. I tried Nmap with no luck(it lists every port from 1 to 65389). e.g

PORT      STATE    SERVICE
1/tcp     open     tcpmux
3/tcp     open     compressnet
4/tcp     open     unknown
6/tcp     open     unknown
7/tcp     open     echo
9/tcp     open     discard
13/tcp    open     daytime
17/tcp    open     qotd
19/tcp    open     chargen
20/tcp    open     ftp-data
21/tcp    open     ftp
22/tcp    filtered ssh
23/tcp    open     telnet

    I'm confused as to why all of these services are showing as open. – Polynomial Mar 13 at 14:29

If it's your server, you will know just by looking at the running services. When you are there, run netstat and probably you will see LDAP listening only on localhost.

Remotely, if the server is listening on localhost, you cannot know just by running nmap, the port will not answer for the public interface. You cannot access it even if it's running.

What you can do is use the NMAP FTP Bounce to scan the internal network.

PS: if this is your server, why would you run chargen, daytime and so? I haven't seen any legit use of those services since last century...

PPS: The last possible TCP port is 65535, not 65389...
