Dedicate a single MBR partition ... There can only be one OpenBSD MBR partition per hard disk." I can't make much sense of what you describe here, but to me it looks like it suggests that you're using a single disklabel which spans more than one MBR partition. Or even moving around the disklabel at will. If so, would you be willing to publish something like a howto on this subject?. Or else tell us where to find one? I know about multiple OpenBSD installations inside a single set of subpartitions, but that's still a single MBR partition. No fdisk or disklabel involved after initial setup, but probably more vulnerable than what you describe here. Bill > I'm surprised more people don't do this.

[Soekris] no time-of-day clock registered on net5501, FreeBSD 8
Hi, I'm running FreeBSD 8.0-BETA1 on a net5501 and I'm seeing the following kernel warning during bootup: warning: no time-of-day clock registered, system time will not be set accurately I've noticed the clock skew rate is pretty high and I'm wondering what other impact it'll have. Is it going to make traffic shaping inaccurate? Any way of solving this? I've pasted my kernel config below. Any help appreciated!

There are two properties of concern here, solar reflectance, thermal emittance, A stainless box might be shiny but it's ability to reject heat e.g. by transferring it to the air is much worse than aluminum and most metal enclosures will get less reflective as they sit there in the weather and oxidize which is why you'll find most radio enclosures that are designed for this application are either powder coated, or painted white. for one example see: http://www.fab-corp.com/product.php?productid=16377&cat=278&page=1 I don't as a rule spend a lot time measuring the albedo of objects placed on my roof, but I'm sure there's a physicist around here someplace. > Alex Samad wrote: >> On Fri, Jul 17, 2009 at 11:13:52AM -0400, Steve Clark wrote: >> >>> Poul-Henning Kamp wrote: >>> In message <4a6060f4.4050...@netwolves.com>, Steve Clark writes: > I am using a 4GB Transcend CF 266x exterme speed to run CentOS with a lot > of > read/write activity.

Re: [Soekris] Readdressing the "cooling" question....
I'm glad to get back to the crux of the issue, which is reducing heat :) I don't need any HDD drives. A 1GB flash is enough for my needs, which are very specific. With 512MB of RAM the Net5501 should hold all my projects in RAM and on a RAMDisk so I'm not even worried about read/write speeds. I'm mainly worried about the boxes getting too hot out in the sun. Perhaps using an unpainted, un-powdercoated box might be enough? That would be a shiny silver, would it not?

I have a system for quick recovery in case of a disaster. I only use half of the disk. When I install a new version of OpenBSD, I use the other half of the disk. That way, if a disaster happens, I can quickly boot, run fdisk -- changing the bootable partition, and then reboot into my previous system. In the above fdisk output, partitions 0 and 2 are my current system, while partitions 1 and 3 are my last and next systems. After I install a new system onto partitions 1 and 3, partitions 0 and 2 will become my last and next systems. (Using 2 partitions like this is a holdover from the days when the bootable partition had to be in the first few cylinders of the drive.) I'm surprised more people don't do this. It provides for very quick and easy recovery in the case of a disaster. (I've only ever had such a disaster once; I've been using OpenBSD since late 1996.) The other advantage of this system is that it provides an easy means for seeing how I did things previously. I can quickly run disklabel, use an empty slice to point to one of my old slices, and then mount it. After I'm done I can run disklabel again and put it back. So I never want to use the entire disk for OpenBSD. Therefore, I will need to remember to escape to a shell and run "fdisk -u" when installing to a virgin disk. It would be nice if the OpenBSD install procedure checked for the lack of a valid MBR, and installed one automatically (after asking); that would save some people from experiencing the problem I experienced.

Re: [Soekris] Soekris BRICK [was Booting] Problem
Hi Soren, with all due respect: is this really how things should be done? Having followed this list for quite a while now I've come to learn that even though it may not always seem that way due to extended periods of deafening silence, the Soekris company do take hardware issues seriously, and will eventually come up with a fix, even at their own expense. Great. Documentation is another thing. In my humblest of opinions, everything listed below (and more, like "what are those pin headers for", for example) should be found on the Soekris web site, either in the form of a net5501 manual, a comBIOS manual, or both. You just can't label the Wiki as "unofficial" (and let the user base do the work, and take responsibility for its contents), and then refer to it as a company to answer questions from users. I myself was involved in setting up the Wiki (and proud to be part of it - man, did that thing get off the ground fast!), and while I can only speak for myself, I'm sure that my fellow contributors will agree that the Wiki is about sharing experiences and giving new users some background info, perhaps with a promotional aspect (nothing wrong with that, is there?). It was never intended as a substitution for official documentation. At this moment, the references are pointing the wrong way.

Re: [Soekris] Readdressing the "cooling" question....
I've seen some inexpensive iterations of ssd that in fact use more power than disks (also see the toms hardware article on the subject). not something I've ever had happen with a CF card. I have some early example of super tallent 16GB MLC sata SSDs from 2007 which aren't to bad on the power front but turn out to be about half as fast as the transcend udma mode 4 slc compact flash cards from the same era which have about half as many channels. I'd go CF in a 5501 unless I had some performance or capacity consideration that dictated an alternate form factor. Michael A.
