I would like to point out that Glen Turner discovered my ... uh, deliberate mistake. I meant, of course, that you use the PPS driver (22) for PPS, and the SHM driver (28) for GPS, and you don't use the NMEA driver (20) at all, unless reasons. I have mentioned that I owe Glen a beverage of their

As an addon to the above, they only support bridging of 2-3 MAC addresses. Which is probably not an issue with a single device, but it's insanely annoying if you run multiple devices doing PPPOE behind a bridged modem. So I'm curious.. What ARE folks using as a bridged VDSL modem that supports

I was rebuilding my local network over the weekend, and as part of that I had to relocate and reconfigure my Stratum 1 NTP server. As I was fine turning it, I discovered a significant number of Au NTP servers are misconfigured, and I thought I'd post a few quick tips here, for anyone providing a
