Gentlemen, As always, the feedback here is outstanding. I forgot that ntp uses UDP and I wrote a rule using TCP! When I changed it to UDP, it all started working.
Thanks

26628 in this case is the pid. ntp always has an destination port of 123 so you can write your iptables rule with that.
Two other things to remember:
ntp uses UDP, not tcp. So your iptables rule should be something like iptables -A INPUT -p udp --destination-port 123 -s ip.of.hobbit.server -j ACCEPT
The ntp.conf on the host you want to check must be setup to allow queries by the Hobbit server.
