Frank4DD 's NTP server

After adding support to the reference clock driver and sucessfully compiling ntp, its time to verify it all works together. Before starting ntp, I had to create a symbolic link for the expected device file /dev/wwvb0 to the serial port device file were the receiver is connected to. Then the configuration file ntp.conf got the following lines:

server 127.127.34.0 prefer
fudge 127.127.34.0 stratum 0 flag1 1

plus some added lines for access control and all is ready. Combined with Solaris 9 operating system, I expect to be accurate down to one millisecond. A higher accuracy can be achieved with special kernels working at higher time precision, combined with switching on the PPS feature in the receiver. With my feedback to the NTP team, I am now maintainer for this reference clock, feel free to send me questions and I'd be happy to help. Good luck with your time! - End -
