RE: OT: NTP hardware
For a solution developed by amateur radio operators have a look at: www.tapr.org in the area titled TAC32. May be some help however please note that some construction is required. Software is available for to maintain system clock of a linux system very accurately however I cannot recall what is was called. I am sure it would be outlined at the above website.

Yeah, I talked to Truetime - they don't want to sell me a card and let me do a UNIX solution; they want me to purchase a rack mount time server. Which potato/woody software are you referring to? I'm sure they're other places to get these boards. Just need an antenna and some software so talk to it, I guess. I've already got an antenna attached to the GPS receiver as mentioned above. The GPS receiver has several clock outputs that should drive some card in a server just fine ... I just haven't found that card yet :) Thanks for your reply. -- Nathan Norman Eschew Obfuscation Network Engineer GPG Key ID 1024D/51F98BB7http://home.midco.net/~nnorman/ Key fingerprint = C5F4 A147 416C E0BF AB73 8BEF F0C8 255C 51F9 8BB7 pgpV2qidQIJFW.pgp Description: PGP signature
