Sermon on Open Systems
Ladies and Gentlemen, lend me your eyes for a brief moment for some feeble words of praise for your efforts. The other day a friend of mine, for whom I have installed an OpenBSD system, mentioned that he had costly experience in the past with small shops and proprietary systems that cannot benefit from economies of scale. I told him that this was not the case with the machine I put together for him, that many hundreds of thousands of people over many years had worked on what I gave him for little more than a song and a dance. Yesterday I installed a Vista machine in my doctor's office, because that's what they bought. While I was able to make it talk internet right off the bat, for the life of me I could not convince it to see some XP boxes in a local workgroup (Link Layer Topology Discovery be damned). A Windows "Guru" was able to make it talk today with no more effort than a magic incantation MS had given him. Over fifteen years ago I worked a stint for MS, ostensibly to build a test suite to demonstrate the conformance of their email(MAPI) product to RFC 822 etc. I couldn't because it wasn't. I did manage to find some deep problems in their compiler and discovered they were using and early gcc (on SCO) to build it with. I then wrote a tool in Prolog to generate test basic code for their systems and promply found myself fired for "Software Piracy". They use similar tools today to test their products. What I'm saying here is not exclusive to MS, but common to many proprietary systems groups. I've worked for companies like Motorola, Lockheed, Lear and Mikoyan. MS had no "engineering culture". No documents more than some sketchty design docs and "running code". Because of this their systems have an 18-month half life: every year or two they _must_ reinvent the wheel because they've lost the human skill that made the previous version. So it's ASP or .NET or some reinvention of the internet that's shiney and new every few years. And it may make them rich but does nothing good for their customers' businesses: just another tax on their resources. Contrast this with OpenBSD and kin like Net/FreeBSD. I can make a machine running a 15 year old version of BSDI or SunOS interoperate with the latest revisions of these. Nobody has chopped slots in the roof beams to make way for a fancy doorway that's 13 centimeters taller than the building codes. And the bearing walls still touch the floor and footings that they bear on. Why is this? Many reasons, I suppose, but at the bottom of it there's your personal pride. And everyone else who has ever worked on this stuff from the some long-gone guys who worked on the first Berkley systems to people in places like Mumbai, Shanghai and Novosibirsk. Their names are on their work. Even long dead guys like Al Turing are acknowledged in this: none here says his work was for nothing, that "fuzzy logic" means his head was "soft" (yeah, I've heard that, no shit:) No one here needs to erase the past to make themselves look good. You know, after MS fired me, calling me a thief didn't stick. So I had to be a closet pervert, and sociopath and worse. My taxes were audited and my driver's license deleted. People jumped out of bushes to beat me up for things I've never heard of. On Sept. 11 2001, I spent the night in Gaol, under suspicion of something or other that didn't stick either. And my personal life makes The Crying Game look like Leave it to Beaver. So I have some idea about what you all must face, motivating yourselves each day to "do the right thing". But let me give you some assurances. MS employs mebbe 70k people, and another hundred K or so in dependant groups. That sounds big, but it's a little job-shop compared to you all. There's a hundred million who know something of open source systems and the brightest minds on the planet are among you. This is the Big House you are building with standards and sources that are open to the critical thought of every bright girl and boy on planet. Even the dead are with you, for this is God's work you do. Duncan (Dhu) Campbell

I just need to read the documentation, but pf will be running locally. Once I figure it out, I wanted to replace my Netgear with a soerkis box running openBSD. Now, I had the timeouts before enabling pf, and I haven't seen them lately, but I haven't been aggressively downloading with bittorrent either. I hope to test this weekend once I figure out what I need to do to provide meaningful results. Thanks, Brian Looking for last minute shopping deals? Find them fast with Yahoo!

OpenBSD Team: Pure Party is now hosting a HTTP mirror at http://pureparty.org/pub/OpenBSD/ . This is rsync'ed on a daily basis from other OpenBSD mirrors. We are hosting this because we use OpenBSD as our server's operating system and wish to support it in this way. Feel free to include this in the available public mirrors collection. If there is something not right with this mirror please let us know and we would be more than happy to resolve it. Thank you, Preston Connors Pure Party

My original test was capped at 384Kbps (i.e. 48KBps). I have tried it with 256Kbps (32KBps), 128Kbps (16KBps), etc. I have also managed to sustain HTTP and FTP connections to my server at 500+Kbps for days at a time with no problems before. If upload was a problem, I would expect this usage situation to cause problems as well. More importantly, I do not experience the latency when I am simply "seeding" (only uploading). I only have this problem when BitTorrent is making large numbers of connections to download. I had some extra time today, and swapped out the OpenBSD box for a NetGear router. I am no longer experiencing the latency problem. I will continue monitoring the problem for another 48 hours or so, but my initial conclusion is that the problem is with the OpenBSD box. Either this is a hardware problem with my box, or it is a software bug. Given the number of posts experiencing difficulty with BitTorrent I am inclined toward the latter as opposed to the former. I'm going to see if I can get another OpenBSD box to test this on, but it won't be a Blade100. I can also try adding an extra network card and not using gem0 (the interface with the problem).

Nevertheless will try to disable apm and pcibios this weekend.

Performance Issues of Intel Quad Port NIC
Hi Everyone
We recently purchased an Intel PRO/1000 GT Quad Port network card and
decided to run some stress tests to make sure it could maintain gigabit
connections on all four ports at the same time. I ran the test with five
computers and iperf-1.7.0 (newest version of iperf has speed issues with
OpenBSD). The computer with the NIC ran the iperf server in upd mode and
the four other machines ran as iperf upd clients.
The first test was using the GENERIC kernel
2 ports could sustain 900Mbit/s connections with about 30% packet drop rate
3 ports could sustain 900Mbit/s connections with about 80% packet drop rate
4 ports could sustain 900Mbit/s connections with about 95-99% packet drop
rate
The second test was using the GENERIC.MP kernel
2 ports could sustain 900Mbit/s connections with no dropped packets
3 ports could sustain 900Mbit/s connections with about 10% packet drop rate
4 ports could sustain 900Mbit/s connections with about 30-50% packet drop
rate
The only disturbing thing about these tests was that I also did the same
test on Gentoo, and I could sustain 4 900Mbit/s connections with only a 3%
drop rate. I found consisten results with the PRO/1000 MT Dual Port card
as well, which has the same controller, the Intel 82546GB. I then tried
the dual port card on FreeBSD FreeBSD 6.1 with the stock install which
does not appear to use multiprocessors and it could maintain 2 ports at
900Mbit/s without losing packets. Unfortunately FreeBSD 6.1 does not
appear to support the 4 port card.
I did some tests on an OpenBSD 3.8 machine and found the same problem.
Is there any explanation for the speed difference? I have tried tweeking
some sysctl values to no avail. Is there something else I can test for on
the card? I'd be happy to run these tests again for any changes that are
made.
Here is the demsg of the test machine:

Your task is not complete when it is configured. You have to know how to detect a failure, replace a failed drive, move drives to a new controller, etc. Don't have a spare controller? How will you get your data off if the controller fails? If you DO have a spare, how do you use it? If you think it's easy or magic happens, you may end up in big trouble. btw: at least in my case, the PE2800 with a 4/Di card has no beeper. If the drive fails, you either need bioctl to tell you or notice the color change on the display of the machine. "bioctl ami0" makes a really good line in your daily.local file... Nick.

This is a bad analogy because you can't do anything with the other 75 km/h. A better analogy would be a network connection that does not allow e.g. torrent traffic to exceed a particular fraction of the bandwidth. Or, if you want to find something to do with cars, a motorway with a separate lane for slow going vehicles (the slow moving vehicles will still be slow even though the other lanes might be empty).

I got curious and tested a bit around and am able up my ping latency up to 9 s (then I got bored :-). I *think* (at least here) incoming connections are more of an issue than outgoing ones, and traffic shaping (as in bandwith limiting) doesn't help much. Not traffic shaping doesn't help either. This is on a 3M/512k ADSL (Arcor/Germany) with a soekris and pppoe. I have not yet looked if its just a pps issue with my soekris (in that case there should be no latency problem at about 1/20th the available bandwith.) I could imagine that some equipment not up to the task at the provider could keep tabs on my states, but I don't see any reason why. (Yes I know, there's this new evil data retention law, but the providers don't even know what exactly they have to log and they are not exactly keen on implementing it). --knitti
