You can get the whole thing going quickly. Majdi has also had good luck with this unit (perhaps he wants to chime-in, heh pun unintended) regarding a few other devices.
The Netburner NTP sample app works well enough for basic home use, although I get better timing performance out of a fleet of hand modified Soekrii. I've been modifying NET4801s to include internal Motorola Oncore timing receivers (this is a tight fit, but doable, in the factory cases), or to break out their second serial port for connections to external reference clocks. (I have one connected to a TrueTime TL-3 to use WWV as a backup to GPS, but it can also be a travelling GPS NTP server with, say, a Garmin GPS18lvc connected.) You can make your own sub-$150 NTP server -- I'll spare the list the details, but those that are interested should see: http://puck.nether.net/~majdi/ntp/ Feedback is appreciated -- I've only spent about an hour on this doc, and it assumes a lot of familiarity with FreeBSD. I will try to flesh it out more as I have time. Cheers, --msa
