Are you aware that Windows XP (SP2 at least) enables NTP by default...
yeah, windows enables it, I believe macos enables it, and I presume most linux distros do too[1]. If it's so prevalent then why don't we see 123/udp from all IP's then? Why do we only see things like port 80 + port 53 traffic on some IP's? Surely they should also be doing NTP?
The installed base of machines that are not running any flavour of XP, never mind XPSP2, is pretty significant. There are still 'net-connected computers out there running Win95! Prior to XP, Windows didn't come with an NTP app at all, AFAIK, and even the XP and (IIRC) XPSP1 shipped with it disabled by default. Most users don't care if their clock is out of sync, unless it's so far out that they actually notice. -- Matthew Poole "Don't use force. Get a bigger hammer."
