Currently, my time server is a Sun v240 with a 32-pci gps card (with a proprietary Solaris driver) attached to our gps receiver via an sma cable up to the roof of my building. As I'm migrating almost all of our Solaris servers and services over to CentOS, I'd like to know what other people are using for time server hardware. Any suggestions? -- Andy Harrison public key: 0x67518262

Any suggestions?Not knowing what country your from but at a U.S. taxpayer I have no reservations about using time.nist.gov myself, some people think it's rude to directly query stratum 1 servers. I typically have 2-3 NTP servers per location behind a load balancer and my internal servers sync against the load balanced VIP, and the NTP servers themselves sync against time.nist.gov nate

But if it is working OK, I would just leave it running unless the hardware is going south. -------------- next part -------------- A non-text attachment was scrubbed...
