Hello all,
I would like to synchronize several computers to a NTP server in a LAN
not connected to the internet. My NTP server uses its own clock and the
NTP clients do not known server's IP. Therefore I need to use broadcast
or multicast synchronization.
In the server machine, I run xntpd daemon using the following
/etc/ntp.conf file:
server 127.127.1.0 # local clock
fudge 127.127.1.0 stratum 10
driftfile /etc/ntp/drift
broadcast 192.67.79.255
broadcastdelay 0.008
authenticate no
disable auth
# Keys file. If you want to diddle your server at run time, make a
# keys file (mode 600 for sure) and define the key number to be
# used for making requests.
# PLEASE DO NOT USE THE DEFAULT VALUES HERE. Pick your own, or
remote
# systems might be able to reset your clock at will.
#
#keys /etc/ntp/keys
#trustedkey 65535
In every client machine, xntpd is running with following /etc/ntp.conf
file:
driftfile /etc/ntp/drift
broadcastclient yes
broadcastclient 192.67.79.255 # listen on default 192.67.79.255
broadcastdelay 0.008
authenticate no
disable auth
# Keys file. If you want to diddle your server at run time, make a
# keys file (mode 600 for sure) and define the key number to be
# used for making requests.
# PLEASE DO NOT USE THE DEFAULT VALUES HERE. Pick your own, or
remote
# systems might be able to reset your clock at will.
#
#keys /etc/ntp/keys
#trustedkey 65535
And then the problem is that the computers clients don't synchronize
with the computer server.
Best regards. Thanks.
