Windows 10 + Ubuntu (shell)

Submitted by tarvid on Thu, 10/27/2016 - 08:41

Recent Windows 10 updates have enabled running bash on Ubuntu on Windows. There are several howtos, the one I happened to use is  I got "root" as the default user; if you got something else, lxrun /setdefaultuser should allow you to change to "root".

5 outages in the last 30 days

Comcast explanations were:

2016-09-28 Head end hub facility failure

2016-10-06 damage at the plant

2016-10-11 animals

2016-10-14 animals

2016-10-20 damage at the plant

"damage at the plant" is pretty vague and includes vandalism, trenching, acts of nature, and a zombie apocalypse.

"animals" is pretty specific but includes rats, dogs, alligators etc.

The head end failure was hardware which they repaired pretty fast.

Not much consolation but these events were preceded by 6 months of relative calm. We could all use a break.

Fiber cut unexplained

Image removed.

It looks like the first outage ended with a temporary repair which was followed by perhaps a more durable fix. In between we had problems with the TWR edge router in Galax which made for a bruising week. 

New life for an old Nuvi

Submitted by tarvid on Sun, 10/02/2016 - 11:44
I bought a Garmin Nuvi 1450 at the recent Pender Flea Market. It is about 7 years old but Garmin graciously offered a firmware update. Garmin wants $90 for lifetime maps for this device so I searched and found newer maps in the 'net. The new map is larger than 2 GB and the 1450 has only 2GB so I searched at Staples for 4GB microsd card. The smallest was 16GB and 'net wisdom is that all Nuvi's will support 8GB. So I went to Microcenter and bought 8GB microsd cards for $6. I stuffed the microsd card into an adapter and plugged it into my Dell Studio, formatted as "FAT".

TWR router(s) DHCP

A wireless user called in a panic when his Internet connection went down. Dispatched Ray to the site and suggested bouncing the radio. That means disconnecting the cat5 cable from the POE to the radio, wait 5 seconds, plug it back in, wait two minutes or so. No luck. The POE is inside, the radio is outside. The easiest and least expensive fix to try is replacing the POE. Ray has one in the van and replaces the POE. Yay the Internet comes back up. Not so fast, a few minutes later the Internet is down again. Time to retrieve that POE from the trash.

Configuring a NanoStation as an AP

Submitted by tarvid on Sun, 09/25/2016 - 12:52

By default, a NanoStation wants to be a “station” or client. The screen shots below are after configuration. That’s good in that my NanoStation is working as an AP and bad in that it doesn’t show the fumbling I did to get there. Out of the box with your laptop connected to the primary port and your IP address set to, enter
