Some statistics from the router at the cabin
sip0 is a GRE tunnel between the router and the colo box in Seattle, the payload of which is encapsulated as ipsec traffic before being transmitted over the Ubiquity equipment to the switch that the CenturyLink DSL modem attaches to. I don’t get centurylink easter eggs in my search results when I use this interface.…

Relatively high sustained rates detected along I-405
$ scp moonunit.colliertech.org:/mnt/downloads/sh1-disk-20140420T070034.xz . cjac@moonunit.colliertech.org’s password: sh1-disk-20140420T070034.xz 76% 534MB 11.1MB/s 00:14 ETA Come on little internet! You can do it! You can push 100Mbit! I remember when this was the fastest I could send data across my LAN. Not bad for a 20 mile shot up I-405. Sorry if I caused any congestion there, folks.…

Windows is *still* loading files
I’m moving the active directory server off of hardware on to the hypervisor. I think if I boot the drive as USB I can install the virtio disk drivers on the system. Fingers crossed! Only thing is that this first boot off of a USB device takes *sooooo* long!

NIST::NVD::Store::SQLite3
I published an SQLite3 storage back-end to NIST::NVD on the CPAN. It’s pretty quick. About as fast as the DB_File one, but without the down side of being tied to DB_File. It shouldn’t be too difficult to re-factor this code to any DBI-based database. MariaDB anyone? I know it works on Debian. The nightly CPAN…

blog optimizations
Thanks to some recommendations from Jeremy, Pierre and Jeff, this blog should be running a lot less slowly. I’ve installed memcached, set up wordpress plugins, tuned apache MPM parameters, tweaked iptables and tc rules and beaten on the blog with load testing scripts. It seems that it will now reliably handle around 10 concurrent requests…

Running a console cable to the radio
So, I’m attaching a radio to the chimney. I don’t want to have to bring it down every time I need to flash the firmware, so I’m also running an rs-232 cable up to it along with the PoE data/power cable. Since they don’t have anything pre-built, I wired one myself. I also made a…
