As you can see, 2TBdisk1 has failed and is unavailable. Since these SATA controllers support hot-swap, I just hooked up the new drive while the box was running. FreeBSD didn’t automatically detect the new drive, so I had to instruct it to rescan the SATA device. Normally I would expect atacontrol reinit to do this, but I ended up having to detach and attach the appropriate ata chain to get it to see the new drive.

[chip@sumo ~]$ sudo atacontrol detach ata2
[chip@sumo ~]$ sudo atacontrol attach ata2
Master:  ad4 < SAMSUNG HD204UI/1AQ10001 > SATA revision 2.x
Slave:       no device present

With the new drive now being recognized, I applied a GEOM label to it, then replaced the failed drive in the ZFS pool.

[chip@sumo ~]$ sudo glabel label 2TBdisk4 /dev/ad4
[chip@sumo ~]$ sudo zpool replace storage label/2TBdisk1 label/2TBdisk4

Overall a remarkably painless process, all without taking the machine offline!

The configuration change on the Eye-Fi Manager side was easy enough, simply selecting FTP as the upload mechanism and filling in a few fields. For the server side of things, I decided to go with ProFTPD, largely because I’ve used it in the past and the configuration is pretty simple. I’d never used FTPS before, but it’s pretty easy to enable with ProFTPD, just a few configuration directives:

TLSEngine on
TLSLog /var/log/proftpd/tls.log
TLSProtocol SSLv3 TLSv1
TLSRequired on
TLSRSACertificateFile /usr/local/etc/kyzoku.2bithacker.net.cert
TLSRSACertificateKeyFile /usr/local/etc/kyzoku.2bithacker.net.key
TLSVerifyClient off
TLSRenegotiate none

However, this doesn’t appear to work. Based on the xferlog and tls.log, it appears the Eye-Fi client was connecting, but the data session was failing, but it did give the helpful message of “client did not reuse SSL session, rejecting data connection (see TLSOption NoSessionReuseRequired)”. This option is undocumented, and is actually “TLSOptions NoSessionReuseRequired” (note the plural), but it does solve the problem. Apparently clients are expected to reuse the TLS session between the control and data channels, but Eye-Fi doesn’t.

So, that’s working, but now my Eye-Fi card isn’t able to be read in either of our cameras or my laptop. Not sure what happened, but it appears the partition table became corrupt this evening. The card still had the only copy of a lot of our Comic-Con photos on it, and I really didn’t want to lose them. First, I decided to get a disk image of the SD card using Mac OS X’s Disk Utility. Then, I had remembered hearing about some open source software for recovering images from damaged cards, and after a quick Googling, I came up with PhotoRec.

PhotoRec is extremely easy to use. It opened up a terminal window with a curses interface, prompting through selecting a disk to scan, a place to save the found files, then initiating a scan of the Eye-Fi, turning up all of my missing images, along with a handful of other files that I didn’t realize were on the card (including an SQLite database, maybe used by Eye-Fi?) So happy I didn’t lose all those photos, and will have to work on getting them uploaded. Unfortunately, I think I’ve lost the ability to geotag those photos though…

The meeting itself was pretty casual, just some announcements and just general chatter for most of it. I’m hoping to have more organization for next month, perhaps with some discussion topics or a quick presentation. One person brought up the topic of media center computers, so maybe we can find someone to talk about their experience building such a thing with open source tech. I’ve taken a stab at it in the past with my MythTV box, but was never terribly happy with the results, and just use a WD HD TV Live to stream stuff from my storage server today.

Overall, I think everyone had a good time, and I’m hoping this will be a successful chapter.

In the past I had used a Linksys WRT54g running dd-wrt, configured to be a wireless client and acting as a bridge, but for streaming video and gaming I don’t really like using wireless. I had replaced the wireless bridge with a long piece of cable running around the living room and into the office, but that would have been really ugly to run into the closet. So, over the weekend I decided to pick up a Linksys PLK300, a pair of Powerline AV adapters, one with a built-in 4 port switch. Brought them home, plugged them in, and it just worked. I’m somewhat impressed, I was expecting some sort of issue, since I have one of them plugged into the surge protection side of a UPS.

So now in the front closet I have the cable coming into the apartment to a 2-way splitter (previously a 2-way then a 4-way, which may have been causing some of my signal issues) then into my cable modem, which connects to one side of my FreeBSD router/file server, which then connects to a WRT54g running dd-wrt, which provides wireless connectivity, then the single port powerline adapter plugs into that. Then in the entertainment center, it’s just the XBox 360 and TiVo connected to the powerline adapter with the 4-port switch.

Overall I freed up a 5-port switch, an 8-port switch, a bunch of Cat5, and some space in the office.

Next, I think I’m going to reconfigure the WRT to do some VLANs, trunking them into my FreeBSD box, and put my Fonera and DynWiFi Meraki on their own VLAN.

And so it went till today. The audio issue just resurfaced. I’m sitting here watching History HD off my TiVo, with no audio. First it was quick cut outs, now it’s just totally silent.

I suspect it’s something with the HDMI audio decoder. My suspicion is that it overheated and did some permanent damage to itself. I should probably contact the repair guy again and find out if the replacement parts were also under warranty, as it’s probably going to take another set of replacements to make this thing work again.

At this point though, I’m tempted to chuck this one off the balcony and go buy a Sharp AQUOS. We’ve got three of those at work and they’re running great. I suppose this is what I get for trying to save a buck and going with the cheap brand.

That jumbled mess is a Geek Code, a somewhat out of date, condensed representation of me. Given that the guidelines of the Code haven’t been updated since 1996, I’ve started looking into alternatives.

The first one I came across was OmniCode, which offers a similar syntax and a greater flexibility. However, the actual guidelines don’t seem to be well thought-out and the resulting code takes up too much space.

My second finding was the Hacker Key, which is again inspired by the Geek Code, and provides a further condensced format with updated parameters. I created a key pretty quickly, and tried the following on for size:

Chip Marshall <chip@2bithacker.net>        http://weblog.2bithacker.net/
v4sw5PUhw4/5ln5pr5FOPck4ma4u6FLOw5Xm5l5Ui2e4t4/5ARWb7HKOen6a2Xs5IMr2g6CM

It’s a little wider, but only two lines overall, and conveys approx the same amount of information to someone who knows what they’re looking at. I thought it looked kindof odd though, so I shuffled the components around and added in my PGP key ID, resulting in:

Chip Marshall <chip@2bithacker.net>
v4sw5PUhw4/5ln5pr5FOPck4ma4u6FLOw5Xm5l5Ui2e4t4/5ARWb7HKOen6a2Xs5IMr2g6CM
http://weblog.2bithacker.net/                        PGP key ID 43C4819E

It’s still a little wider than I’d like, but I could trim out a parameter or two to bring it back down. Haven’t decided if I really like it overall though yet.

Maybe I just spend too much time on these sorts of things…

PS: Oooh, what if I put the Hacker Key under the URL/PGP key line?

Chip Marshall <chip@2bithacker.net>
http://weblog.2bithacker.net/                        PGP key ID 43C4819E

Hmm…

So, I’m starting to think I need to start selling some services on the box in order to get a regular flow of money coming in. Cheap virtual web hosting seems to be the easiest to do, if I can find buyers who would rather go for my little locally hosted box over one of the larger services. $10/mo seems fair to me, and at that rate I only need to get 9 customers to cover the hosting costs. If I could even get 3 or 4 it would be a big help.

If anyone has ideas for other services, or would be interesting in hosting, let me know. I suppose I should do this in some sort of official fashion via 2 Bit Hacker Consulting.

Over the weekend Delia and I got the new TV hooked up, and it’s looking good. I also decided to go ahead and get the Xbox 360, and I’m rather glad I did, as the TiVo HD turned out to be dead on arrival. For some reason it was stuck in a reboot cycle and couldn’t get past it’s initial welcome screen. TiVo support was pretty cool about it and are doing an advanced ship RMA on it, so hopefully I’ll have that soon. The Xbox has been filling the time we would have normally spent watching TV, so it works out, I suppose. For games, we picked up Assassin’s Creed for me, DDR and Katamari for Delia.

Unfortunately my bad luck with new devices has extended to the Garmin my dad sent me. It powers up then complains that it has no maps and is therefore useless. Garmin’s online support is equally useless it seems, as they try to load pages from RFC1918 private address space, or try to redirect you to hosts that don’t exist in the DNS. Their phone support is, of course, closed for the holiday. Hopefully tomorrow will be more fruitful.

All in all though, I’m happy. I still think Delia spent too much on me, and I feel bad that I didn’t get her more, which seems to happen every year.

One somewhat interesting thing is that I finally broke down and ordered a shiny new HDTV last week. It’s an LG 37LB5D, which is a 37″ widescreen LCD at full 1080p resolution. To go with it, I also ordered a TiVo HD so I’ll have some HD content to watch. They should both arrive tomorrow, at which point I’ll get to have fun getting CableCARDs from Comcast. Oh yeah, and if anyone out there is interested in a used 27″ Sony WEGA tube, let me know. It’s too big to really go anywhere else in my apartment.

The new TV has also got me thinking about picking up an Xbox 360. I haven’t really been doing a lot of console gaming lately, but it looks like there are some decent new games out there, and the whole online thing looks interesting. I think Delia wants one too, though I’m not sure why. Maybe I’ll just get the PS2 hooked up again, and if we actually use it, I’ll get the newer thing.

Other than that, not a lot going on. Some people have asked what I want for the upcoming holiday, so I’ve started tagging some things as “want” on my del.icio.us. Nothing terribly fancy. I’m trying to get the apartment cleaned up and presentable so that people can actually come over. If that project gets complete soon, maybe we’ll have some people over for a holiday party of some sort.
