Come on. Let's keep this civil. While I agree that one should check ones OWN ISPs servers, your example has you pulling from ISPs furthest from you NOT closest to you. Basically you are pulling from an ISP you're not paying for. Also I've looked at my ISPs ntp servers. The reason I won't use them is that they are not properly configured. I say this because they only have 2 sources when I do "ntpq -pn my.isp.server". You should mention what is a "good" server is (which is a whole article in itself). 4 servers is the bare minimum. I keep 9 active servers in my ntp.conf. Brad had a whole discussion posted somewhere on this. Step 3 is where you get into trouble. You're telling people that it's ok to use ANY server that someone else is using. The problem with this is that some require you to contact them first. You're basically saying, "Don't worry about the cost that the server provider incurs." Not cool, IMO. There's an underlying issue that I what to get to. Why do people need to be a st2 server? I used to think that to run a pool server that I HAD to connect to st1 servers. It's the same mindset that is causing st1 servers to go offline. If a person REALLY needs to connect to a st1 then it's worth their expense of running an st1 themselves. If not, being an st3/4 server is fine. Just pick the 9 servers with the lowest delay with offset and jitter <10-15. Finally you CAN have more servers without actually impacting them or yourself much. server ip noselect maxpoll 12 minpoll 7 noselct prevent your ntp from choosing it as a server. Prevents unstable ntp. maxpoll you know lengthens the poll max. minpoll lengthens the poll min. Also a nice thing to do for servers that you want to "monitor". _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
