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:
1) 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
2) The ntp.conf on the host you want to check must be setup to allow
queries by the Hobbit server.

Henrik
