Any time you're looking at network protocols, the one obvious place to look is the RFCs. Just do a web search for 'rfc ntp' to find the relevant ones. In my case, the search results pulled up a couple of good-looking hits from ietf.org (the Internet Engineering Task Force - those guys are the authority on this sort of matter), plus the Wikipedia article for NTP, with a section "Relevant RFCs", which would make good reading. Enjoy! Networking's awesome fun. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
