During latest leap second test activities, I was tinkering with my test NTP server and I encountered an error: "RAND_load_file /root/.rnd not found or empty"
There is not much help on internet. You just need to seed with the following command:
dd if=/dev/urandom of=/root/.rnd bs=512 count=1
And if you have an error: "crypto_setup: random seed file not found error:"
Add “crypto randfile /dev/urandom” entry to /etc/ntp.conf without the quotes.
