OpenBSD's Common Address Redundancy Protocol
Jessie writes "OpenBSD just gained high availability functionality in the form of a new protocol named CARP, the Common Address Redundancy Protocol. This feature was a long time in the coming due to Cisco's patent on VRRP, requiring the development of something completely new and more secure. This article on KernelTrap offers details on OpenBSD's impressive new protocol, from how it works to how it got its name."

Wait, isn't BSD dead?

I suggested a different name (same four letters, different order, took a cheap shot at Cisco in the process), but Ryan didn't seem to care for it for some reason. 8)
BTW, the kerneltrap article renders perfectly in IE, but not Mozilla 1.4?!
But we already know from earlier today that OpenBSD 3.4 was a real stinker in these tests. The installation routine sucks, the disk performance sucks, the kernel was unstable, and in the network scalability department it was even outperformed by it's [sic] father, NetBSD. OpenBSD also gets points deducted for the sabotage they did to their IPv6 stack. If you are using OpenBSD, you should move away now..
What We Can Learn From BSD
By Chinese Karma Whore, Version 1.0
Everyone knows about BSD's failure and imminent demise. As we pore over the history of BSD, we'll uncover a story of fatal mistakes, poor priorities, and personal rivalry, and we'll learn what mistakes to avoid so as to save Linux from a similarly grisly fate.
Let's not be overly morbid and give BSD credit for its early successes. In the 1970s, Ken Thompson and Bill Joy both made significant contributions to the computing world on the BSD platform. In the 80s, DARPA saw BSD as the premiere open platform, and, after initial successes with the 4.1BSD product, gave the BSD company a 2 year contract.
These early triumphs would soon be forgotten in a series of internal conflicts that would mar BSD's progress. In 1992, AT&T filed suit against Berkeley Software, claiming that proprietary code agreements had been haphazardly violated. In the same year, BSD filed countersuit, reciprocating bad intentions and fueling internal rivalry. While AT&T and Berkeley Software lawyers battled in court, lead developers of various BSD distributions quarreled on Usenet. In 1995, Theo de Raadt, one of the founders of the NetBSD project, formed his own rival distribution, OpenBSD, as the result of a quarrel that he documents on his website. Mr. de Raadt's stubborn arrogance was later seen in his clash with Darren Reed, which resulted in the expulsion of IPF from the OpenBSD distribution.
As personal rivalries took precedence over a quality product, BSD's codebase became worse and worse. As we all know, incompatibilities between each BSD distribution make code sharing an arduous task. Research conducted at MIT found BSD's filesystem implementation to be "very poorly performing." Even BSD's acclaimed TCP/IP stack has lagged behind, according to this study.
Problems with BSD's codebase were compounded by fundamental flaws in the BSD design approach. As argued by Eric Raymond in his watershed essay, The Cathedral and the Bazaar, rapid, decentralized development models are inherently superior to slow, centralized ones in software development. BSD developers never heeded Mr. Raymond's lesson and insisted that centralized models lead to 'cleaner code.' Don't believe their hype - BSD's development model has significantly impaired its progress. Any achievements that BSD managed to make were nullified by the BSD license, which allows corporations and coders alike to reap profits without reciprocating the goodwill of open-source. Fortunately, Linux is not prone to this exploitation, as it is licensed under the GPL.
The failure of BSD culminated in the resignation of Jordan Hubbard and Michael Smith from the FreeBSD core team. They both believed that FreeBSD had long lost its earlier vitality. Like an empire in decline, BSD had become bureaucratic and stagnant. As Linux gains market share and as BSD sinks deeper into the mire of decay, their parting addresses will resound as fitting eulogies to BSD's demise.
So much for living..
The evil duo quickly subdued the little lab penguin. They strapped the now helpless animal's head to the sex table with hot leather. David had the urge, and removed his pants, which were now bulging. After slipping off his briefs, David tightly fastened the leather straps and was ready to begin.......
David began to "grease up". Shoving endless amounts of Vaseline and baby oil all around the penguin's ass, he slid his purple head firmly into the penguin's tight asshole. Even though the penguin was slightly unconscious, screams of pain were constantly being emitted. Ted reached for the chain whip and smacked the penguin's soft nose until its face was soaked with blood. Now, with the penguins head drooped over the edge of the table, David continued his sex hunt. His now tingling cock was pushed deeper and deeper through the thick layers of skin which covered the bowel tract. Five, six, seven, then finally all eight and 3/4 inches were plunged deep within the animal's love canal.
David's manhood tingled with every slight movement of the now half alive penguin. He began rhythmically sliding in and out, moaning with pleasure on every thrust. David worked himself into a hot orgasm. The blood, now coming steadily out of the penguin's ass with every thrust of David's pelvis, could be heard dripping on the floor. David's rate increased and with a final push, he spurted creamy white love gel far up into the penguin's bleeding ass.
The blood and cum mixed together on the floor, which had now accumulated a large puddle. Unknown to David, the semen had acted as a powerful enema for the penguin and out ushered the contents of its intestine. The stool was loose and soft. It fell to the ground with a soft thud and broke into small pieces. The obnoxious smell caught David's attention, and no sooner had he fallen to the ground and began licking the large puddle of blood, sperm, and stool. Exited at David's enthusiasm, Ted dropped to his knees and also began to slurp the foul mixture.
After cleaning the floor with their tongues, David and Ted checked on the battered lab penguin. It was barely able to hold its head up, as it had lost control of most of its motor functions. Feeling no pity for this sexually mistreated animal, they unstrapped it and tossed it across the room, only to make a loud and deep thud against the wall. Its blood soaked fur left spatters of red stains everywhere it touched. Its bodily fluids freely surged across the tiled floor.
Then with a look of extreme satisfaction, both David and Ted lit up some smokes, gathered their belongings and quietly left the hospital ground.
Misread CARP as CRAP? :)

It is common knowledge that *BSD is dying. Everyone knows that ever hapless *BSD is mired in an irrecoverable and mortifying tangle of fatal trouble. It is perhaps anybody's guess as to which *BSD is the worst off of an admittedly suffering *BSD community. The numbers continue to decline for *BSD but FreeBSD may be hurting the most. Look at the numbers. The erosion of user base for FreeBSD continues in a head spinning downward spiral.
OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of BSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.
Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.
All major marketing surveys show that *BSD has steadily declined in market share. *BSD is very sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among hobbyist dilettante dabblers. In truth, for all practical purposes *BSD is already dead. It is a dead man walking.
Fact: *BSD is dying
The *BSD Wailing Song
What's left for me to see
In my ship I sailed so far
What can the answer be
Don't know what the questions are.
And after all I've done
Still I cannot feel the sun
Tell me save me
In the end our lost souls must repent.
I must know it is for certain
Can it be the final curtain
As long as the wind will blow
I'll be searching high and low.
Who knows what's really true
They say the end is so near
Why are we all so cruel
We just fill ourselves with fear.
And heaven and hell will turn
All that we love shall burn
Hear me trust me
In the end our lost sould must repent.
I must know it is for certain
Can it be the final curtain
As long as the wind will blow
I'll be searching high and low
Final curtain
Final curtain
pressed to bsd lips

I don't want to start a holy war here, but what is the deal with you BSD fanatics? I've been sitting here at my freelance gig in front of a BSD box (a PIII 800 w/512 Megs of RAM) for about 20 minutes now while it attempts to copy a 17 Meg file from one folder on the hard drive to another folder. 20 minutes. At home, on my Pentium Pro 200 running NT 4, which by all standards should be a lot slower than this BSD box, the same operation would take about 2 minutes. If that.
In addition, during this file transfer, Netscape will not work. And everything else has ground to a halt. Even Emacs Lite is straining to keep up as I type this.
I won't bore you with the laundry list of other problems that I've encountered while working on various BSD machines, but suffice it to say there have been many, not the least of which is I've never seen a BSD box that has run faster than its Windows counterpart, despite the BSD machines faster chip architecture. My 486/66 with 8 megs of ram runs faster than this 800 mhz machine at times. From a productivity standpoint, I don't get how people can claim that BSD is a "superior" machine.
BSD addicts, flame me if you'd like, but I'd rather hear some intelligent reasons why anyone would choose to use a BSD over other faster, cheaper, more stable systems.

But you seemed to have missed the Michael Smith one ...
I understand that Theo and friends are pissed off by the IETF, but I really hope that they write an RFC for carp, so that we can have a compatible version for other OSes. Are there any detailed descriptions of CARP on the net yet ?

The record is clear on one thing: no operating system has ever come back from the grave. Efforts to resuscitate *BSD are one step away from spiritualists wishing to communicate with the dead. As the situation grows more desperate for the adherents of this doomed OS, the sorrow takes hold. An unremitting gloom hangs like a death shroud over a once hopeful *BSD community. The hope is gone; a mournful nostalgia has settled in. Now is the end time for *BSD.
And that the tests were run unscientifically with the -CURRENT release...how dumb is that? Shouldn't a fair test be run with a -STABLE release? Silly, silly.
It's hard to say failure when the top 50 uptime websites are all hosted on some variant of BSD. Crazy...
