Zero-Copy TCP and UDP Output in Net

April 3, 2002 by Rob

Bron: [url=http://mail-index.netbsd.org/current-users/2002/05/02/0016.html]Mailing List NetBSD.org[/url]

Jason R. Thorpe heeft recentelijk wat experiementele code toegevoegt aan de [url=http://www.netbsd.org/Releases/current.html]NetBSD-Current[/url] die ervoor zorgt dat er zero-copy mogelijk is voor TCP en UDP aan de transmissie kant. Deze veranderingen zouden voor ernorme verbeteringen kunnen zorgen voor FTP‚ WW en Samba servers. Je kan Jason’s announcement [url=http://mail-index.netbsd.org/current-users/2002/05/02/0016.html]hier[/url] lezen voor meer details.

Op tests met embedded systemen met gelimiteerde memory‚ ging de preformence van ~6500KB/s naar 11100KB/s over een 100baseTX-FDX btw.

[quote]It’s also worth noting that a server application that mmap’s a file and then sends it out to the network causes the data to be moved exactly once: from disk to memory. The rest of the “data movement” is done by VM mappings and reference counting tricks. This could mean significant performance improvements for FTP‚ WWW‚ and Samba servers (NFS servers can’t take advantage of this yet; they use a different interface‚ which I am going to address separately fairly soon).

Clustering in FreeBSD

Dit artikel bevat een interessant project betreft het clusteren van een paar oude computers met FreeBSD

[quote]My objective is to turn a pile of old corporate Pentium class workstations into a mini super-computer before my boss has them donated to charity. I consider that charity a waste of perfectly good cluster nodes! Waste not, want not?. So the race is on to get my cluster project moving forward.

Jordan Hubbard resigns from FreeBSD

April 3, 2002 by Rob

Bron: [url=http://daily.daemonnews.org]DaemonNews[/url]

Door het gebrek aan tijd‚ energie‚ plezier en doorzettingsvermogen heeft Jordan Hubbard‚ een grondlegger van het FreeBSD project‚ ontslag genomen bij het FreeBSD core team. Ondanks dat Hubbard zijn handen van de administratieve taken afhaalt‚ is hij nog wel van plan om te blijven coden aan FreeBSD.

De onstslag brief:
[quote][i]From: Jordan Hubbard
Subject: Resignation from FreeBSD core team
Date: Mon‚ 29 Apr 2002 13:55:05 -0700[/i]

Guys‚
After giving it a fair bit of thought over the last few weeks‚ I have decided to step down from core. I am doing this for a variety of reasons‚ any one of which would probably be sufficient grounds in and of its own and‚ taken in combination‚ certainly constitute ample justification for doing so:

The first and certainly foremost reason is a lack of time and energy. I simply no longer have the time to devote to doing what I would consider an adequate job of being a responsible core member and the “honorable” thing to do in such case is clearly to step down and let the next election hopefully sweep someone else with more time and energy into the position.

Another reason‚ and I hate to say this but it probably needs saying‚ is that being in core is honestly not what it once was. For a old-timer like myself‚ who was used to a core team that was far more cohesive and generally on the same page‚ it’s simply a painful experience a lot of the time. Perhaps this is due to overly rose-colored recollections of the old core on my part‚ and I do certainly recall us having more than our share of disagreement and inefficiency in the past‚ but on the balance core still feels too much like the pre-WWII Polish Parliment sometimes‚ where we’re fully capable of arguing some issue right up to the point where tanks are rolling through the front door and rendering the whole debate somewhat moot. I’m also not blaming this on the democratic model we’ve adopted‚ a stance which would be hypocritical at best since I’m one of the folks who argued strongly in favor of it‚ but I guess it’s going to take a few more iterations before we get it right. It will also probably be a lot easier for truly new people who don’t have a lot of preconceived notions of what core is to make that happen.

Finally‚ it also bears noting that while being part of the FreeBSD project is many things‚ it should always be “fun” to at least some degree for its participants or there’s really not much point in being involved. Being in core‚ where one gets to deal almost solely with conflict resolution and bureaucracy‚ is not fun in any sense of the word and while being in core constitutes the bulk of my involvement‚ without any cool development work (which I also haven’t had time for) to counter-balance it‚ it simply leaves me with less and less enthusiasm for FreeBSD. Better to pull the ejection handle now than to let things get to the point to where I’m simply bitter and annoyed ALL of the time vs merely some of the time. 🙂

While my time has been very limited lately‚ I hope to get back to a point where I can start actively contributing to FreeBSD again‚ and the best place for me to make those contributions is not in core. I would therefore like to officially tender my resignation and request that I be removed from the core mailing list at the earliest opportunity. Thanks!

– Jordan

Network Forensics: Tapping the Inte

April 3, 2002 by Rob

Bron: [url=http://www.oreillynet.com]OReilly Network[/url]

In dit artikel wordt een stukje geschiedenis van het monitoren van netwerk verkeer verteld en hoe dit is uitgegroeid tot de huidige beveiligings systemen.

[quote]The incident in the Persian Gulf became a cause celebre in the years that followed. Tsutomu Shimomura bragged about the incident in his book Takedown. Many experts in the field of computer security used the story as proof‚ of sorts‚ that the U.S. military was asleep at the switch when it came to computer security.

One of the more dramatic outcomes of the incident was a videotape played at the annual meeting of the American Association for the Advancement of Science in February 1993 — a video that showed each of the attacker’s keystrokes‚ replete with mistakes‚ and the results‚ as he systematically penetrated the defenses of the ship’s computer and scavenged the system.

Linux 2002 – Open Source Business c

April 3, 2002 by Rob

Bron: [url=http://www.linux2002.nl]Linux2002.nl[/url]

Binnenkort is alweer de “4e editie van hét Business congres & expo op Open Source gebied in Nederland” zoals ze het zelf aankondigen. Mischien stiekum toch wel een klein beetje intressant‚ ondanks dat het over een inferieur systeempje gaat (*BSD all the way!!)

Op de site van de expo kan je je [url=http://www.linux2002.nl/linux2002-sub.asp]inschrijven[/url] voor gratis toegangskaarten voor dit evenement wat gehouden wordt op 26 september in Ahoy te rotterdam‚ doe je dit namelijk niet en besluit je toch te gaan kost het je namelijk 27‚- EUR aan de ingang.

[quote]Vorig jaar weer het jaar waarin [i]Linux[/i] vaste voet aan de grond kreeg. Dit jaar heeft het Duitse parlement gekozen voor [i]Linux[/i]. AOL is in zee gegaan met[i]Linux[/i] (Red Hat). En dat Microsoft Open Source met een kankergezwel vergelijkt is tekenend voor de inhaalslag die [i]Linux[/i] momenteel binnen het bedrijfsleven maakt. Ook onze overheid ziet het belang van open source in. Het ministerie van EZ heeft het daarom opgenomen in haar nota “de digitale delta”.

BBned wil hulp gemeentes bij uitrol

April 3, 2002 by Rob

Bron: [url=http://www.webwereld.nl]WebWereld[/url]

DSL-aanbieder BBned is een ‘praktijkgericht programma’ gestart onder de veelzeggende naam PubliekPrivaat. Het doel: het stimuleren van het gebruik van DSL in heel Nederland. Lokale overheden moeten hieraan bijdragen, vindt BBned.

Het jonge bedrijf wil nog dit jaar samen met gemeentes waar nog geen DSL-voorzieningen beschikbaar zijn, deze alsnog realiseren. Tot nu toe heeft BBned op eigen initiatief al zo’n driehonderd wijkcentrales geschikt gemaakt voor DSL. De kosten hiervan bedragen volgens het bedrijf per centrale gemiddeld 125.000 euro.

Testing FreeBSD-Current

April 3, 2002 by Rob

Bron: [url=http://www.onlamp.com/]OReilly Network Onlamp[/url]

FreeBSD -current wordt getest en de uitkomsten hiervan kan je in dit artikel terugvinden. Programmeurs kunnen hulp bieden door adviesen te geven over hoe een bug opgelost kan worden. DP1 is geen versie voor mensen die met Unix/ FreeBSD willen beginnen of c00l willen doen.

[quote]If you’re a programmer‚ feel free to take a stab at a fix. The FreeBSD folks would be delighted to get a suggested patch for a problem. If you’re not a programmer‚ that’s OK; just be certain to include your dump debugging session.
