Network Time Protocol (NTP) at UGA

On campus, we use the Network Time Protocol (NTP) to synchronize the clocks on computers.

WSG provides executable code for NTP daemons for the platforms we support which can be found on the anonymous ftp server at ftp.uga.edu/pub/unix/packages/xntp.uga. Note also that most modern Unix-like OS'es comes with a NTP package already. If so, we highly recommend using that package as your default NTP client.

The Time Servers are:

• time1.uga.edu
• time2.uga.edu
• time4.uga.edu

Here's a simple ntp.conf for a recent version of the ntp.org ntp reference implementation:

# General Policy
restrict default ignore
restrict 127.0.0.1 

# Policy for Time Servers
restrict 128.192.1.9 mask 255.255.255.255 nomodify notrap noquery

restrict 128.192.1.19 mask 255.255.255.255 nomodify notrap noquery
server 128.192.1.19

# Make the system clock be a "clock of last resort"
