Solving the routing issue
Topic: technology, opinion Link here

I should have called Aussie Broadband yesterday about the routing problems that I discovered on Sunday. But I dreaded the encounter, so I put it off.

But it had to be done, and today I called up and was connected relatively quickly to Ashika, who of course didn't understand. What kind of router do I have installed? She could only see one IP address. I tried to explain, and she decided to escalate to “level 2” after only 3 minutes. And after a total of 5 minutes, the call was done: she would send me an email, to which I should reply with the problem details.

That's actually quite reasonable, and quite a difference from recent encounters. But how do I explain in a manner that will get the problem involved? Ask an expert, Philip Paeps.

First question: what tools do I use? So far I have been using the rather strange invocation

=== root@lax (/dev/pts/7) ~ 90 -> whois -h " -v"
AS      | IP               | BGP Prefix          | CC | Registry | Allocated  | AS Name
NA      |    | NA                  | AU | ripencc  | 1991-05-01 | NA

And I don't even understand the syntax. I know the basic syntax for whois, but it doesn't describe the -v parameter. I'm still not 100% clear what it is, but it seems that it's passed to a special version of whois at, which also proves to have a web interface that doesn't really say any more.

So: in the course of the discussion, Philip came up with the following tools:

In the process, Philip identified a nick “cyrusone”, also known as Mark Price, who helped me through the maze a year ago. He is “a prince among men” and Philip's upstream.

In the background, it seems that Philip contacted people whom he knows at Aussie:

*trouble* A look is being taken by an aussiebb person with a clue                 [13:08]
*trouble* do you have your WAN IP?  They're trying to find where your route should go
<Groogle> xl0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
*trouble* my transit friend found an edge friend who is now looking around :)     [13:14]
<Groogle> This looks like it might happen faster than the typical support call to the [13:15]
          support people.

So the whole thing took 16 minutes. On occasion I've taken longer to authenticate with Aussie “support”. And yes, it works.

Some of the tools show interesting graphic representations. The RIPE page shows:

In summary: it helps to have friends. And it shows how big a difference there is between Aussie's front line mail configurer “support” and the people behind the scenes

Eye progress
Topic: health Link here

I had hoped that the bubble in my eye would be gone by now, but no such luck. It's getting smaller, and on a couple of occasions I got a smaller one that then went away again. But by evening it was still not gone.

Sourdough lifetime?
Topic: food and drink, history Link here

It's been fifteen years since I started cooking with sourdough. In that time I have tried various sources, including making my own from kimchi juice, but in October 2017 I bought one on eBay, and I've been using that ever since.

But somehow things are changing. I now have something like the 50th generation of the starters, and starters that would happily keep for months are becoming dark and mouldy within the 2 months that I need them to last for. And looking back to October 2017, it seems that they're also less active. How did that happen? I can replace them, of course, but it irritates me.

I can see clearly now
Topic: health, opinion Link here

The bubble in my left eye has been shrinking continuously, but somehow not as fast as the one in my right eye three weeks ago. That bubble was much larger, and it took 163 hours, almost exactly a week to disappear. This one started at about the size that the right bubble had after two days, but it still took 155 hours. But this evening, finally, it was gone. All done bar the floaters.

So, for the first time in decades, I can see clearly in the distance. Really? After the first operation I had the distinct impression that my focus was too close by 0.5 dioptres, which was maybe confirmed by the follow-up examination two weeks later. But now I can see clearly, read email on TV better than I have been able to for months, and I can read text on my computer monitors at the 67 cm distance that you'd expect from 1.5 dioptre glasses.

But sometimes I get the impression that my focus shifts in relatively short periods of time, and that distant things are not as sharp as they could be. From time to time the vision is also smudged, maybe something to do with the eye drops. In addition, the view of each eye doesn't quite correspond; hold a hand in front of one eye and then the other, and the view changes both in shape and position. Take the hand away and I have perfect stereoscopic vision. Clearly it's a good idea to wait for things to settle.

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.
