Re: CPU criteria for OpenBSD firewall
Thanks to all of you for this interesting discussion. My OpenBSD firewall will only be doing PF as I totally agree that a firewall should have the least userland application running as possible of course if your budget permits it. So far I have around 340 rules (as the number of lines in the output of a pf -sr) and a state table of around 12-20k entries depending the time of the day. As per your recommendations I will go with a higher CPU frequency and less cores as packet filtering still only takes place on one single core. I might also experiment if I should use bsd.mp or the standard non SMP bsd. I also agree with Nick that CPU is of course not the only criteria but the rest I have luckily already sorted out :) For example by using nice and modern Intel 10 Gbit/s NICs, CompactFlash industrial grade flash storage, redundant setup with 2 firewalls and CARP, etc. OpenBSD does a great job here, I don't even want to imagine the price of such a setup with C***o hardware. Cheers

Realistically, most modern fast CPUs (let's leave out special cases like the Intel Atom, though even that might do it for you) will do the job just fine. Modern Atoms (avoton, rangeley) will do just fine for this amount of normal traffic. If the ruleset is super-complicated or if there are very high PPS counts (which is by *far* more important than absolute bandwidth) _or_ if there is a reasonable chance of that happening during the expected life of the machine, then you might need faster. Just choosing between the two suggested CPUs and taking only the basic description of workload into account I'd probably choose the lower-power one. Or asked differently, which are the importants criteria to look at first for a CPU intended to be used in an OpenBSD firewall? Discussing the merits of a CPU that's 95% idle vs. one that's 90% idle really misses a few points. If I were looking for a box, I'd look at more important issues: (in no particular order. And your criteria WILL differ from mine) * How fast a machine boots. * Availability of repair and upgrade parts * Low cost, so I can get a second machine and CARP 'em together. * General usability of the system and support by OpenBSD * Good bus structure for application * Well-supported NICs * Power consumption. * Quiet * Simple Availability of out-of-band console access.

This will clearly matter if you're also doing IPsec or so. Also, last I checked for desktop chips, i3 was 2 core hyperthreaded (4 threads) while i5 was quad core not-hyper (still 4 threads). OpenBSD still isn't really aware of hyperthreaded, so you'll get better, more consistent performance from the i5. The i7 then goes to four cores, 8 threads, which is less than ideal for openbsd. There's also some variation in the availability of various VT extensions. Last two points probably don't matter much for a pure firewall passing packets, but the few hundred mhz gained may not be a worthwhile trade for flexibilty if you ever intend to repurpose the box.

Won't i386 use less memory making it more efficient up to about 2 GB of RAM which this machine has? Yes, also i386 will make better use of cache on the cpu which means some software will be faster. However amd64 provides a larger virtual address space which has security benefits (better ASLR). It also has more registers which means other software will be faster. Of course, if RAM would be added you would regret not having installed amd64... Yes to this too. It is a trade-off.

Short path to making Android APKs under OpenBSD?
Somewhere I read that Android now only officially supports their own Android Studio. Eclipse might work but needs to be newer than even OpenBSD 5.6's version. Gradle might work but seems to need Groovy, there seems to be no end to the bloatware. Android Studio is a 1 gig download and wants 4 gigs of RAM to run. Can't it be done with make or cmake? This reminds me of the gobs of software for etext publishing when an epub file is just a zip file with a certain directory structure inside. An APK file is just a zip file. I don't need easy and GUI, I can follow a checklist or write something that does it for me. I've written some Java but I'd rather use c and maybe GTK. -- Credit is the root of all evil. - AB1JX

The last few months, I've been unable to tag other people when commenting on Facebook. I've tried resetting Firefox, disabling add-ons, deleting old profiles, reinstalling the browser, and even doing a fresh install of Firefox on a new OpenBSD installation. All to now avail. I suspect the user agent setting to be the culprit and have tried experimenting with various strings. Some of them enables me to tag other people, but messes up other things. Would anyone using Facebook be so kind as to provide me with a working user agent string for Firefox (35.0) ? Thanks, Erling PS. Just checked and neither Seamonkey nor Chrome will let me tag people in comments. This is getting weird... I've noticed this as well lately. It's obviously a change on FB's side, not on OpenBSD's side (since you have gone back to old versions to verify the problem still happens on versions I know it didn't). Curiously, I think I have noticed it impacting my (completely stock) android phone, too, though that may just mean it is over due for a reboot. I'm not losing any sleep over it, however. I seem to have low expectations for people coding not-stupidly. Nick.
