Posted January 10, 2015 By Landis VLast night I finally got around to doing a little bit with the Pogo Mobile units I had installed Debian on. Not much so far, just got dnsmasq loaded on the unit that will become my DHCP and DNS server (replacing the same functionality on my router, so the next time I swap out a router I don’t have to worry about transferring internal DNS or DHCP reservations).
Haven’t done much of anything with the unit that I will be configuring as a CA, but did run across a couple of good reads on how to do a CA “right”. The OCSP article fills in a piece I’d like to have if I’m going to go to the trouble of setting up my own CA “for real”.

I stopped at Charter yesterday and exchanged one of my digital cable tuners for a CableCard, so I am anxious to get my HDHomeRun set up and start playing with it. I don’t like the way my CATV cable is organized, and it’s also older RG-59. Having purchased some RG6, I’m now in the process of centralizing that system, pulling new cable to at least a couple of locations, and will probably use the opportunity to put an ethernet drop in my garage as well.

Using git (and Puppet) to manage configurations
Posted January 5, 2015 By Landis Vhttp://sickbits.net/nagios-deployment-automation-tips-and-tricks/
Specifically with Nagios in the case above.

Great use of EEM to backup config. It would be interesting to integrate Puppet into this setup and have the system receiving the configs first diff to see if there were any changes, then check with the puppetmaster to make sure everything was kosher.

Recent mini-PC/router devices of interest
Posted January 5, 2015 By Landis VRockTek RT-A1, priced at $65 on NewEgg Flash on 1/5/15. Quad core, HDMI output up to 2048 x 1536. Appears to be only a 10/100 ethernet, but has a couple of USBs to which GigE adapters could be connected for up to 480Mbit theoretical throughput. Also has a composite video out, which could theoretically be paired with one of these 4.3″ LCD “backup camera” displays for a convenient method to apply updates, etc. Caveat is that there does not seem to be much hackery on it to run Linux natively, but it is tempting to pick one or two up to play with and see what could be done.
Also ran across this Foxconn AT-5570 (manufacturer page here, also on sale at NewEgg Flash for $90, though it would need to have RAM and storage added). Higher price and lower performance would make this somewhat less appealing.
The Foxconn was perhaps most interesting because it led me to the Jetway motherboards with multiport ethernet daughterboards. This auction page had a six port GigE model. The four port daughterboard is the Jetway ADE4RTLANG, and several of the Jetway mini-ITX mainboards include dual ethernet ports natively. Quite a bit higher priced, but might prove useful at some time.
Also interesting was the Odroid-C1 currently selling at the same price as the RPi, and their intro/getting started kit with the required SD card as well as a breakout board and some basic electronic components to get familiar with the device is on sale for under $70 through January 7th when paying with PayPal. The C1 is, I believe, almost pin-compliant with the header on the RPi. It has a quad core 1.5GHz processor, 1GB DDR3, and a gigabit ethernet interface.

Pretty good board list, including a couple with dual ethernets, which is something I’ve been wanting to have.

Asus RT-N16, possible capacitor issue
Posted December 8, 2014 By Landis VI’ve been using an Asus RT-N16 router with Tomato firmware for just over two years now, and the other day it died on me. It would power up for just a second or so if I unplugged and re-plugged it, and I confirmed it wasn’t just a bad transformer with another 12V/1A power supply I had around. I was able to swap in a Netgear 3400 I had on hand and get back online quickly so I didn’t need to worry about it, but wanted to see if there was anything I could do with the N-16 as it has worked very well… and has all my config in it :/

The whole family was sick today, so I finally had a chance to dig into it a bit. I first checked the warranty and see that I’m a couple of months past the two year point (purchased in July 2012), so I went ahead and opened it up. Upon doing so, I discovered a slightly swollen 680uF 16V capacitor near the power connection. A bit of Googling seems to indicate this is a pretty common problem (here, here, and here are just a few samples), so I’ll have to do a little scavenging and see what I can come up with for a capacitor.

U-Boot w/ MMC/SD-card booting for Pogoplug Series 4
Posted December 3, 2014 By Landis Vhttp://forum.doozan.com/read.php?3,7477,10982
Just bought one of the mobile units today. This thread appears to have some instructions on getting Debian set up on the SD. Will have to come back to it when the unit arrives and I have a couple of minutes. Thinking this could make a great router/firewall.
