nuxx.net Is Down

Hey everyone… My server at http://nuxx.net is down, and no, I don’t know why. I think Waveform is moving locations, but they didn’t notify me, so I’m just not sure what’s up. I have a support ticket open about it, but they haven’t replied yet. So, we’ll see… I hope I don’t have to move providers.

Having stuff like this working is fun:

The Trashwall and its associated article are nearly done. :D

Fucking Comcast

Arraugh. So, I have Comcast service for internet access, but not television service. I have a TV, but I only use it for pre-recorded stuff / video games / etc. However, when I got home today I had a note hanging next to my garage which reads:

While performing work in your neighborhood, it was determined that the cable TV line and/or equipment inside your home does not meet technical specifications established by the Federal Communications Commission (FCC).

The problem appears to be a leak of the cable TV signal. Signal leakage has the potential to cause interference with with aeronautical, police, and other communications. Comcast is required by the FCC to record and promptly repair signal leaks.

Please call Comcast at 1-800-865-9787 to schedule an appointment for one of our technicians to repair the signal leak.

If you are unable to contact Comcast within three (3) business days, we will be required to interrupt your service until the necessary repairs can be made.

So, I called and told the operator that I only have internet service and then asked what should be done about the note. The operator then first told me that I should just ignore the note, since I don’t have TV service. When I reminded her that I have internet service and that the note says the service will be terminated if I don’t call, she put me on hold to talk to a supervisor.

After she returned to the line we began to set up an appointment, but there were only 9am – 12pm or 12pm – 3pm windows open for technicians to visit, all the way through the end of March. Even better, the end of March is the furthest out she is able to schedule visits.

Great, eh?

So, she logged that I called and suggested that I just call back tomorrow and see if another slot is open.

I’m not sure what to do now. Maybe wait and see if my service actually gets switched off? <sigh>

UPDATE: I rejiggered the wiring just inside the house so that there are no unterminated connections. Hopefully that will sort it out. The root issue may very well be my fault, but I’d hope that Comcast would have some more reasonable appointments available. Hopefully my service won’t be interrupted now that things should be sorted out.

OpenBSD Bug Report

Yay, the bug report I submitted, #5372, for an issue I experienced during a headless install of OpenBSD/macppc has been posted. My workaround is here in the Trashwall article.

(In short, everything for a headless / via serial console install works automatically except setting up /etc/ttys so that the console goes to the serial port.)

Merging .reg Files

Do any of you have a good way to merge .REG files together?

I’ve got four files and I want them to all become one. Key values don’t need to be merged, the lines can simply be duplicated if they are different. I just need to slam four files together and get rid of the duplicate lines.

Trashwall Failure

Hrm, the Trashwall failed sometime during the night.

I think it may have bad RAM… I’ll have to hang a serial console off of it so I can actually watch it go down.

<sigh>

This stuff is never as straightforward as it should be.

500 Days

Today marks over 500 days of uptime for rowla.nuxx.net.

Also, work is horribly busy lately. I guess that’s what I get for attempting to move into Engineering.

Compact Flash in the Trashwall

So, I won this eBay auction for some Compact Flash to IDE adapters. As you can see in the image, those adapters are supposed to plug right into a 40-pin ATA port. In the Trashwall I was hoping to plug one of these right into the main board and use it for booting the OS from a compact flash card.

Unfortunately, the seller instead sent me a normal end-of-cable mount adapter, similar to the one used in my MAME Cabinet, except without the second slot. At least it was the newer version which supports DMA transfers, which was one of the big things I wanted.

This evening I took the adapter, screwed some old motherboard standoffs into it, then screwed it into one of the Power Mac G4 AGP’s drive trays. Despite being something other than what I wanted to use, it has worked out pretty well.

It turns out that the two fastest (specification) cards I have are my Sandisk Ultra II 2GB and the el-cheapo Micro Center-branded 2GB card, which are both DMA Mode 2 devices. While this isn’t too slow, it’s not as nice as what I’d get if I were to shove one of the newer Transcend 133x as did with his IBM z50. But, being cheap and trying to keep with the spirit of the Trashwall, I’ll use the spare, leftover Micro Center card.

Now, I just need to install OpenBSD on it again, fit it in the rack, and get it integrated into the network here. Hopefully I can do that tomorrow. For now, beer and relaxing.

NC3134/NC3135

Compaq NC3134 / NC3135

The NC3134/NC3135 set purchased via eBay for the Trashwall arrived today. It’s in such good shape (likely new, as described) that it threatens the Trashwall idea. Thankfully it clearly wasn’t wanted by someone so they let it go for cheap…

Now…

# ifconfig | cut -f1 | sed '/^$/d' | cut -f1 -d":" | paste - - - 
lo0     fxp0    fxp1
fxp2    fxp3    fxp4
fxp5    fxp6    fxp7
gem0    enc0    bridge0
#

That’s a lot of network.

I also took a few photos of the various bits (photo gallery retired), including the G4Port (1, 2, 3), all the ports on the back of the case, all the NICs in the case, the console cable, and a few other things (photo gallery retired).

Many of these photos were integrated into the main Trashwall article, and now I just have to wait for the CF reader so I can finish putting it all together.
