Doctor's appointment
Topic: health Link here

Into town this afternoon to see Dr. Paul Smith. Health First have expanded: they used to be on the first floor, and there were two different pharmacies downstairs, but it doesn't seem to have been worth their while. Now Health First have expanded to take up both floors. Paul is now downstairs, and to compensate for the additional space, his own room is only about half the size of the old one.

No blood tests to talk about today: they forgot to get the pathology request for me. Somehow we got through half an hour anyway.

And when I got home, I got a call from Specsavers to tell me that my new glasses were ready for pickup. They really could have called earlier. But then, once again they didn't notice that I'm due for a visual field test, which requires an appointment. So I'll have to go in again on Tuesday.


Health First: Signs of the times
Topic: technology, general, opinion Link here

Why did the pharmacies downstairs from Health First close down? One potential reason was that Health First made a better offer for the space. But that would only explain one of the pharmacies. The second, UFS, was only there for a year or so.

Another explanation might be that the location is inconvenient. It's not that difficult to get a parking space: there's free parking across the road in Central Square. But I find it takes me about 10 minutes longer to get there than to most places in Ballarat. And like Central Square itself, it seems that the middle of town is atrophying. Clearly Health First finds the location good, but visits there tend to take longer than visits to a pharmacy. Another sign of what the future of the Internet brings?


New ATA, first impressions
Topic: technology, general, opinion Link here

On the way home, picked up the Grandstream HT802 Analogue telephone adapter that I bought last week. No instructions at all! It appears to be from a bulk pack, and it came really with only a power supply and an Ethernet cable.

Never mind, I had already downloaded the PDF of the administration guide, which had been suitably confusing. It's amazing how many apparently obscure settings that these ATAs have. Still, I've been there before. Let's try without the instructions.

Connect up. IP address? Guess DHCP:

=== grog@eureka (/dev/pts/36) ~ 1672 -> arp -a
...
silberapfel.lemis.com (192.109.197.238) at c0:74:ad:37:66:d8 on em0 expires in 1181 seconds [ethernet]

silberapfel was Chris Bahlo's old Apple laptop, the one that died and that I gave to Jamie Fraser in exchange for fwaggle. Clearly this is something new. And sure enough, http://silberapfel.lemis.com gave me a status menu and the option to configure the thing.

What do I need? From Aussie Broadband:

Your VoIP number is 035318....
Proxy Server: AussieBB.nms1.voice.wide.net.au
Registrar Server: AussieBB.nms1.voice.wide.net.au
Outbound Proxy: AussieBB.nms1.voice.wide.net.au
Port: 5060
Authentication Username: same8digits
Authentication Password: fooblah
Caller ID Name: same8digits
Caller ID Number: same8digits

Clearly the last four lines have been changed for my protection, but it's interesting to note that three of the entries are the same. But how much help is it? The menu entries don't match. My guess:

HT802       Aussie
Primary SIP Server       Proxy Server
Local SIP Port       Port
Authenticate ID       Authentication Username
Authenticate Password       Authentication Password

So I put all that in, and also (rather unnecessarily) set the NTP server to eureka. Rebooted the device, and... Status: Not Registered.

OK, what now? What do the log messages say? What log messages? Oh, set the log server to eureka and log level to EXTRA DEBUG, whatever that means. Reboot. And sure enough I got a whole lot of messages:

The first thing to note is that their claim of 30 second boot time is wildly optimistic. The first log message was before boot (clearly not worth mentioning for EXTRA DEBUG). The term “dropbear” is also interesting.

But what are these PROVISIONING messages?

Apr  8 16:33:55 silberapfel PROVISION:  1617863635.670686 could not download https://fm.grandstream.com/gs/cfgc074ad3766d8

Why couldn't it download the data? And why does it want it, anyway? Off to check network connectivity. It has an ssh interface which proves to be a particularly primitive BusyBox:

No way to ping, but since it recognized the name eureka.lemis.com, DNS must be working, and the gateway address is correct, so that should be working.

My guess is that it is set to download its configuration from a default external source. Do I want to investigate further, or first RTFM?

More Pedro acclimatization
Topic: animals Link here

Pedro continues to acclimatize, and he's playing with Nikolai:

He's (unfortunately) not housetrained yet, but there are indications that he's getting there. Yvonne has been able to get him to defecate and urinate on command, which I found impressive. It seems, though, that she has been doing this with other dogs for 50 years, and I never noticed.


Gardeners again
Topic: gardening Link here

Nathan and Bianca along today to do some more gardening. Bryan, who had announced it, didn't show himself. Gradually things are looking better.


ATA installation
Topic: technology, general, opinion Link here

Yesterday's less-than-successful attempts at configuring my new Grandstream HT802 Analogue telephone adapter had a clear message: RTFM. So started with that today.

Not much success. There was nothing in the manual that suggested that I should do anything different. I was left with two clues: firstly, the default port number in the configuration was 5062, not 5060. Why? That's the port number of the server, and it's almost invariably 5060. And then there was this firmware download thing that I had noticed in the log messages. That was clear. The ADVANCED SETTINGS menu (why do these people always shout?) included:

Reset that, remember to both save and to reboot (another 2 minutes), and it no longer tries. But why is it set up to try to load firmware that isn't available?

Apart from that, nothing in the instructions deviated from my guess yesterday. So why doesn't it work? More to the point, how do I find out? Checked the Aussie Broadband web site, which is particularly broken with regards to VoIP (in particular, no links). With Google's help, found a setup guide, which firefox lost again. But it doesn't refer at all to the Grandstream device that they supply, only some other device.

OK, looks like a support call. But it would be good to check alternatives. Fire up Wireshark and see what happens:

How I love Wireshark. I can't even copy the text anywhere. But the error code “403 Forbidden” clearly points to something that Aussie should be able to explain.

On the other hand, I know that it works with the Linksys PAP2. Well, the first account does. This was the second account, and on the second line of the Grandstream HT802. Is the account maybe not set up correctly? Does it work on the PAP2? Off, configure, fix finger trouble, ... yes, the second account works on the the second line of the PAP2. OK, that points to the HT802. Does MyNetFone work on the HT802? Yes.

But first, there are other options. What about trying it on the first line of the HT802? Set that up and... success!

What's going on here? Clearly it's an Aussie Broadband problem. Clearly also now (Friday, 16:00) is a bad time to call them. But now, coincidentally, I have what I want: Aussie and MyNetFone on the HT802. So I can remove the PAP2 and forget the whole thing. I really should contact them and find out what's wrong, but there's no urgency any more. And looking through their offerings, I'm not sure that I want to switch from MyNetFone. It's only about $5 a month difference, and so far Aussie's offering doesn't seem to be well rounded. Where's voice mail? Yes, it's there, but no evidence that they can send it as email. How do I transfer a number to them? Again, maybe it's possible, but the documentation is missing. I need to think out what other functionality I need.

And the HT802? There's nothing about it that makes me prefer it to the PAP2. The menus are even more irritating, and the box looks like a toy:

http://www.grandstream.com/sites/default/files/styles/product_470x470/public/Products/ht802_front_website_0.jpg

What's not clear from that image is how bright these LEDs are. They're irritatingly bright, even when you're not looking at them. But it works, and the sound quality is better than my old, worn-out PAP2.


This page contains (roughly) yesterday's and today's entries. I have a horror of reverse chronological documents, so all my diary entries are chronological. This page normally contains the last two days, but if I fall behind it may contain more. You can find older entries in the archive. Note that I often update a diary entry a day or two after I write it.     Do you have a comment about something I have written? This is a diary, not a “blog”, and there is deliberately no provision for directly adding comments. It's also not a vehicle for third-party content. But I welcome feedback and try to reply to all messages I receive. See the diary overview for more details. If you do send me a message relating to something I have written, please indicate whether you'd prefer me not to mention your name. Otherwise I'll assume that it's OK to do so.
