Hello everyone, If anyone is interested, I have created a HOWTO on running a Motorola GPS receiver connected to a CentOS 7 box via serial port (com1), with 1PPS over DCD. The trick here is that CentOS 7 uses systemd and setup was a bit different. Anyway, everything works. The result is a highly accurate NTP server, Stratum 1. Here is the documentation. http://www.maximaphysics.com/Centos_7_GPS_Setup.html Let me know if something does not look right....

Our primary is a Datum/Symmetricom SSU2000 modular system with a cesium PRS, a rubidium stratum 2E secondary clock, and an OCXO stratum 3E tertiary clock. The cesium PRS is down at the moment, but the rubudium is close enough for current work. The CentOS box runs very well for this...

Hi, I have a server and ten clients in a Gigabit network. The server has 125mbps network bandwidth. I want that the server has 40Mbps bandwidth reserved for client 1 (IP 192.168.5.141), and the rest bandwidth is for all other clients. My script looks like this (I use IFB for incoming traffic): #!/bin/bash export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: htb default 30

One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services.? This begged a question about why every computer would not have a radio module to receive time.? Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system. When I was a student, such questions would have earned
