ntpd is the ntp server. it runs as a local service to keep time
synchronized, and can provide this function to other clients e.g.
running ntpdate. It runs on port 123.
The problem arises when ntpd is running and you try to run ntpdate, as
ntpdate attempts to use port 123 also. Basically, you cannot run both at
the same time.
run `netstat -lnup' as root and attach the output.
