Some historical context on NTP monlist: it's an old debugging interface from the days of the Friendly Internet, when services were more open and people were much less worried about this kind of security. NTP daemons give up a whole lot of information if you ask them; see also the "peers" and "sysinfo" commands, for instance.
Back in 1999 I used these monitoring commands to spider the NTP network, surveying some 175,000 hosts from a desktop workstation. Lots of fun! This kind of survey is much harder to do now because so many systems are locked down. http://alumni.media.mit.edu/~nelson/research/ntp-survey99/ http://alumni.media.mit.edu/~nelson/research/ntp-survey99/
