Please pay attention!!
Nobody understands why you need to use the loopback interface. Nobody
understands how you could believe that the loopback interface could
possibly work with ntp!
This is at least the third time I have seen essentially the same
request. I believe (I didn't check) that all of them came from you.
If you want to use your unsynchronized local clock as a server, doing so
has nothing to do with the loopback interface. Include the following in
your ntp.conf, restart ntpd, and you are done!
# Declare the local clock to be the clock of last resort.
# It will be used to serve time in the absence of any other.
server 127.127.1.0 # Local clock, unit 0
fudge 127.127.1.0 stratum 10
Note that 127.127.1.0 is not an IP address! The loopback interface is
If this does not answer your question, please explain in detail what it
is that you want to do and why you believe that it is a useful thing to
do. Your request, as you stated it, makes no sense to anyone here!!!!!!
