---MD5 Keyfile Configuration

When you have entered all of the keys that you need, enter zero at the next
prompt for a key number.
MD5 keys may contain from 1 to 31 ASCII characters. They may not contain
SPACE, TAB, LF, NULL, or # characters!

Enter the key (1-31 ASCII characters): EndRun_Technologies_LLC

---NTP Authentication Configuration
Do you want authentication enabled using some or all of the keys in
the ntp.keys file? ([y]es, [n]o) y
You will be prompted for key numbers (1 - 65534), that you want NTP to
“trust”. The key numbers you enter must exist in your ntp.keys file. If you
do not want to use some of the keys in your ntp.keys file, do not enter them
here. NTP will treat those keys as “untrusted”.
Clients that use any of the “trusted” keys in their NTP polling packets will
receive authenticated replies from the Tempus LX GPS. When you have entered
all of the “trusted keys” that you need, enter zero at the next prompt for a
key number.
Enter a trusted key number (1-65534) or 0 to quit: 1

broadcast mode, this address is the all 1’s address on the sub-net.
