It'll probably work just fine for good number of clients, but if you care about accuracy, it's not going to be good choice. You can easily test this, add one router as your NTP peer to your linux box, and check in 'ntpq -p' what your 'jitter' is, it's likely order of magnitude more than from dedicated server. WE're seeing jitter of 0.0Nms from our dedicated NTP servers (They don't do HW timestamping, which would further reduce the jitter) -- ++ytti _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
