Many of the pool servers rely on outside sources. My servers don't have reception either. > We limit up/download speed in apps and using wondershaper, yet still our > time is deemed unworthy. My limited experience shows that you can have good connectivity, good ntp software, good hardware, ... but if your upstream time servers are not *really* good then your time will not be so good. Even if your scores in the management system are great people here will find faults and tell you how much your server stinks. However, once you've taken some abuse the people here *will* help you learn and might even help you diagnose problems. My advice is: learn ntpq, et al; set up a machine as a client to compare your server to "nearby" stratum 1 servers; change your server's upstream servers by throwing out the worst and adding new candidates and then *measure* the results. You can't blindly go by stratum number or any other single number, really. You must see how any given server acts as your upstream by using it and measuring. When you change upstream servers you must also give ntpd some time (hours, not minutes) to settle before judging. If it seems like a lot of work... well, it can be. It really doesn't take that much effort, but it takes some time. But when you are done your time server will be better for you and for the pool and won't require too much upkeep. -- Darrin Chandler | Phoenix BSD User Group | MetaBUG [EMAIL PROTECTED] | http://phxbug.org/ | http://metabug.org/ http://www.stilyagin.com/ | Daemons in the Desert | Global BUG Federation
