Today I received an envelope containing three BA6110 chips and some mome rath buttons. Hopefully one of these will resolve the problem I had with the bad BA6110 I received as part of the x0xb0x kit.

It’s done. My Xbox 360 is now working properly via NAT talking through the Trashwall and using WOW! service.
After getting my previously mentioned pf problem on Trashwall sorted out I tested out the Xbox 360 to see if the network test for Xbox Live would pass. Guess what? It didn’t, continuing to insist that my NAT type is strict.
A bit more research (and information which seems to come from this post at Russ’s Blog) indicates that the Xbox Live uses the following classifications for NAT:
Strict: Symmetric NAT.
Moderate: Cone shaped NAT with port filtering or with UPnP turned off.
Open: Cone shaped NAT with no port filtering or with UPnP turned on.
Cone and symmetric NAT descriptions are formalized in RFC3489, and a bit more digging brought up this general how-to for using OpenBSD’s pf, indicating that the static-port directive on a NAT rule (described here in the POOL OPTIONS section of the pf.conf(5) man page) makes OpenBSD do cone-shaped NAT.
So, overall, what did it take to fix it? Well, it was actually three things:
· I switched to Wide Open West for data service, which gave me three IPs.
· While the whole house was NATted through one of the IPs, the Xbox 360 alone has been bidirectionally NATted through another.
·The magic static-port option on the NAT line for the Xbox 360.
Without a second IP I wouldn’t have been able to forward all ports inbound, which without a UPnP daemon (which didn’t go well before) would have resulted only a NAT setting of Moderate.
All of this has been documented in the updated version of the article on the Trashwall, my home’s a firewall / NAT device / switch / whatever built out of an unwanted PowerMac G4.
(In case you didn’t notice, this photo does a good job illustrating the wire in a aperture grill, such as the one here on an Sony KD-34XBR970 CRT HDTV. If you’d like to see the original without the no sign, here’s the small version and here it is at full res.)

UPDATED: This is fixed. See the bottom of the post.
With the move to Wide Open West for data service at home I now have up to three IPs available, all assigned via DHCP. In order to best use them and work around the Xbox Live problems I was having I wanted to do the following:
– Assign one IP to one interface, and NAT everything through it, like normal.
– Assign a second IP to a second interface, and use binat to have my Xbox 360 to basically have its own public connection. (Sort of like being in the DMZ on a Linksys box.)
– Leave the third IP alone for times when I want a non-firewalled connection.
While I have this set up, it doesn’t seem to be working. Here’s my current configuration. If anyone can tell me what I’m doing wrong or offer suggestions, please do so:

One of Roxie’s favorite past times is removing the innards (squeakers, fluff, etc) from stuffed animals. She only plays with those she is given, but once she has one she quickly sets into it. Throughout the week I’d find her taking the toy and pressing it into my hand trying to get me to play with her or watching her lay behind me pulling out hunks of fluff from a new-found inside passage.
Oh, and the crusty look to the fur? Yep, dried dog slobber.

I’d previously posted about how x0xb0x #888 was generating no audio after powerup, and with Roxie now gone I had time to start digging into what was wrong.
I’d already known that the power supply, digital half (sequencer), DAC, and VCO were working fine, so I set to work tracing things back through the schematic from the headphone out. Eventually I found that I was able to see a waveform on the first half of the BA6110, after the op-amp (pins 6 and 7) but before the buffer. I didn’t see anything after the buffer (pin 8).
So, I think I have a bad BA6110, which is one of the rare / hard to find parts in the x0xb0x. This is just what I was afraid of.
Being typically paranoid of my own work I double-checked soldering, checked for shorts, and all the other normal things like that, but I really think the problem is with the buffer.

Last Monday I had Wide Open West CATV and internet service installed. The installer was a nice guy, did just what I wanted, and did a good job putting the new junction box on the outside of the house. As requested he left the Comcast line going into the house, replaced the old splitter, and let me take care of the data side of things (very basic to set up; no Comcastic walled garden crap), and had an MCard for the TiVo.
The only problem I had is that he wasn’t familiar with setting up TiVos and forgot to check for reception of HD channels. A phone call to WOW! service after he left got those turned on and everything was set.
Thus far I’ve been mostly happy with the data service. Tests at DSLReports.com have shown that I can achieve the claimed 15Mbps downstream and 2Mbps upstream quite regularly. Everything has been much faster in real use as well, and uploads to my photo gallery are far, far faster now.
I intend to write up a more technical description of how I like the service, including how I intend to use the three IPs (DHCP assigned) that I’m allocated as part of the service, but that will have to come later. For now I’ve got some other projects to wrap up.

After a bit over a week here it’s time for Roxie to go back home. Danielle arrived here last night right as I returned from Brian’s birthday party, and after some gift returning / shopping stuff she left today with Roxie in the back of the car.

Here, have yet another photo of Roxie, this time with her leaning strongly against my leg wanting me to pet her. One can even see the line down her back caused by her sleeping inverted, leaning against the couch a few minutes earlier. And the nose. The nose!
(For what it’s worth, she’s now laying with her head between the bike wheels seen there chewing on the remains of a rawhide from earlier in the week. She tends to eat all but 1″ of them, then leaves that bit laying around until I won’t give her a new one.)

Normally Roxie drinks out of her water bowl, but given the option she’ll also gladly drink out of bathroom sink faucets. When doing so she doesn’t lick the tap, she just laps heartily at the stream of water.

I just finished watching The Business of Being Born. Despite what the trailer (which will automatically start playing if you visit The Business of Being Born’s website) seems to imply, this film was about modern day midwifery. Sure, the film does touch on the idea that the dramatic rise in number of Caesarean section births is a product of hospitals being more focused on getting women in and out as quickly (and as profitably) as possible, but that strike me as the focus.
