Easiest way to do this is add it to the version in ports. I've never implemented WebDAV in nginx, but I certainly see at least a dozen tutorials on how to do it by searching for it. Unless OpenBSD is doing something slightly crazy with nginx (like they did with apache), any Linux-based tutorial should be generally fine to follow. crazy? hmm.

Chain loading from grub 0.97

First I make sure nothing was erased. grub find /boot (hd0,3,a) grub find /bsd.rd (hd0,3,a) grub find /root/.profile (hd0,3,a) So it's clearly still there. grub rootnoverify (hd0,3,a) grub chainloader +1 grub boot Fail.

I even tried direct booting, but as with every tut and email I've read on the subject, it only leads to a panic. grub kernel --type=openbsd /boot grub boot Panic. grub kernel --type=openbsd /bsd.rd grub boot Panic. Seems I'm stuck. What do I do to chainload openbsd when grub just chainloads itself?

It also seems to require two machines to function at all? Qemu performance is of no issue for my immediate needs and I obviously prefer to use OpenBSD native for many reasons including debugging without wondering if the virtualisation is at fault and it would be nice to have the last resort performant back stop option on a single laptop of an external boot device to run multiple existing OS including the natively installed OpenBSD and say Windows or Linux for certain tasks or unavoidable commercial packages and switch back to native for most things. So I'm hoping I can boot OpenBSD with qemu or Windows or Linux under multiboot or alternatively boot xenserver or something off a usb and select 2 or more of the multiboots to run concurrently.

I tough: So, I X running with no root, I could intall and run anything with the right package manager. So, for now, that's the man concept and it's running at Linux too. https://github.com/TeeBSD/kornbrew Motivations --- I did Kornbrew to suply my needs about installing 3r party software as simple user at: * Cluster environment * Remote Shell account * When I need some specific version or the latest version of some software. * College's students lab. They could install whatever wants, and the machine keeps always as brand new instalation. * Don't need to use root in a desktop or workstation(With or without X). In all of these circumstances, to be root is not a good way to do things. I see a lot of benefits. I think, that's not my only needs. So, I took the beginning of the project to disseminate it and who like the concept, could give suggestions and / or do a more professional design, because I have a lot to do and I don't wanna to wasting my time, working by myself just in my needs. Instead, I could work with others and his needs. What dou you think about the concept.

Apparently the makefile even build the libc and everything so ... We experienced real cases where building when target and host had different sizes resulted in bad code and lots of time wasted trying to figure out what was wrong in the code, when the compiler was the problem. Since there are fast archs for both 32 and 64, simply banning the mismatch was a way to guarantee a known safe setup and stop developers from wasting time on something gcc didn't support. To put it another way: let's say you disable that check and it all *almost* works; if that build's problems resulted in other people wasting time trying to figure out what went wrong, it would be a Very Bad Thing. like those ? : https://gcc.gnu.org/bugzilla/show_bug.cgi?id=31585 I tried it because * qemu not so fast (still runing in background) * my i386 target very slow (and only 128mo ram) * do not want to install x86 on the build machine , currently thinking about dual boot x86/amd64 , i wonder if the amd64 boot could load a 32bit kernel... that would save the Active partition disk trick or the grub use. The i386 and amd64 boot blocks can load both types of kernel. I used to do that until I accidentally toasted the second disk's install and switched to building i386 on my old T60.

For this situation, a UPS only needs to power the machine for a few minutes to shutdown safely, so it doesn't need to be particularly expensive. Quite possibly less than the cost of the drives big enough to hold your 2.7TB filesystem and a backup.

I had an adsl modem that, no matter what you did, you had to use an mtu of 1492, otherwise things being accessed from outside, wouldn't work. Also some issues with UDP downloads where seem, but most applications corrected those. But these are extreme and rare circumstances and, most of them, if not all, can be corrected. Perhaps a second sweep of your network problems might be needed. Anyway, you can take a look at net.inet.ip.mtudisctimeout and play a little with it to see if you can improve your situation without the need to change your mtu on the interfaces themselves. Hardly think that it will be fixed. There are eg. firmware updates for those HP boxes, but can't be updated because after that some stuff is not working. I know, sounds strange,but can't fix whole world. And for wifi setup I made config scripts so MTU is set only here and nowhere else. Now it works as expected on OpenBSD. But thanks to OpenBSD such issues were detected in the first place. Once again thanks a lot to all Now you know what I meant on the previous e-mail that, if OpenBSD was seeing something wrong, it was because there was something, indeed, wrong.

Getting unswapped?

I've seen this before, sometimes it'll stay swapped out overnight until I reboot to clear it. The Gimp was closed hours ago. Is there any command to cause the swap system to do a HUP or something to re-evaluate the situation? Thanks, Alan -- Credit is the root of all evil. - AB1JX

Re: Getting unswapped?
Mostly so when I switch to a different application, maybe on a different page of the FVWM desktop, it isn't sitting there swapped out and it's responsive. I've usually got 20 or more applications open at once (most just RXVT windows) and reboot about once a week. If I invest in RAM I expect it to get used. Seems like Linux and FreeBSD are better about this but I don't use them often. Now I've got 864 free, 25 swapped out (restarted Firefox).
