Just wanted to say thanks and that it works fine here using ubuntu 6.06 so debian users shouldn't have issues either. Only thing I had to install was grace using `apt-get install grace`
Couple notes for us ubuntu / debian users. The peerstats files are kept in /var/logs/ntpstats. On here it keeps the last 10 days with the last 8 days gzip'd. So when you modify the scripts you will have to use gunzip -c on those files. Also the default $work_dir doesn't exist and the $ntp_template path needs to be changed. I was able to get it hacked together in probably 15 minutes, most of that noticing the above issues. And I do mean it's hacked together right now (hence why I'm not posting an example :) ). The easiest to figure out includes and excludes is to just run it without any include or exclude filters, it will then process all the servers in your peerstats file (the 5 or so peers your client is talking to, not the 1000s of people that are talking to your server). You can then see what it uses for the hostnames and filter accordingly. Going to take a look at this to see if there's a way to overlay the server's offset (output of `ntpq -c rv`) with this information since it should generally match what your server is doing. For example I have two good servers that are following the curves of my server on 0ms line, then another server follows the curves but with a +1ms offset. This is more of a concern for us st2+ servers since we aren't going to be as stable as cesium st1 server :) Thanks, John, for mentioning this. I've seen your stats for a while and never really paid much attention to the scripts till you mentioned it.
