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.
