Henrik,
  How did you get the VMIO test to work? I added it to the clientlaunch 
just like all the others but all I get is a green dot on the display 
with no data. gat any ideas?


Regards

Kevin

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.
