NTP server install on linux

I installed NTP server on Ubuntu Server 10.04 using:
[crayon-66226e12433e5493647092/]
The NTP daemon seems working and listening on the 123 port.

However, I was not able to get the time from another machine:

If you have ntpd installed on another machine, you can use your first server in the servers list of your ntp.conf file, or can synchronize one time with the -q option, as follows:
