Hi


I'm trying to set up a NTP server on Fedora for my local network, but it
doesn't seem to work.  I edited /etc/ntp.conf and added a 'restrict' line
for my local subnet.  I then restarted ntpd.  ntpd is now running - I
can see it with a 'ps aux|grep ntpd'.  There are no obvious error messages
appearing in /var/log/messages, just diagnostic messages as it starts up.
However, I can't connect to the server from any other machine.  Running
nmap against the machine would seem to indicate that the port 123 is not
open.


When I run 'lsof -i TCP' there is no mention of 'ntpd' or port 123
anywhere.  This would seem to indicate that ntpd has not opened the port.
However, if I try to deliberately start a second copy of ntpd manually an
error message appears in /var/log/messages for each interface saying that
ntpd cannot bind to port 123 because the port is already in use.


Can anyone explain what is going on and how to fix it?


Thanks,
Peter
