NTP attack message

Hi, all, 
 
I am developing a Nessus client based on NTP.  The attack message I used
looks like this: 
 
"CLIENT <|> NEW_ATTACK <|> 123.41.57.67, 123.41.57.107, congare.cs.edu
<|> CLIENT"
 
I think the format of my list of targets is correct. But the server can
only test the first target and ignore the rest.
 
Any idea?
 
Thanks,
