1.6 Million IP Connections on FreeBSD
An anonymous reader writes "FreeBSD developer Terry Lambert, in a recent posting to the 'freebsd-hackers' mailing list, mentioned that he'd tuned a FreeBSD 4.4 box with 4GB of RAM to achieve 1,603,127 simultaneous IP connections, and goes on to say: 'As far as I know, I hold the single machine connection record for an x86 box.' This is an impressive achievement any way you look at it (though it begs the question of whether or not the box had any resources left to actually do anything with those connections...), and it speaks well of both FreeBSD's capabilities and Terry's skills and knowledge. I'm curious, though, if anyone has approached, matched, or exceeded that number elsewhere?"
*BSD handles 1.6 million connections without dying.
sweet...:-)
as a non native english speaker I had
no bloody clue about the correct use of
begging the question...
thanx

my webhosting box does twice that during peak hours, but then i'm hosting free porn so it doesn't count ;)
Post the address of that box here. We'll give it a real stress test.
I can't say that I don't give a fuck. I've just run out of fuck to give.

"I'm a 'Prior Artist'."
What has been tested is simply the number of concurrent connections. More practical would be simple retrieving of say 1kb data from a database and printing it out on a very simple HTML, and checking the maximum number of THESE connections. In effect trying to really httpblast DDoS style the FreeBSD with sheer number of connections. The box will have to be massive with 4GB RAM at least (we're testing OS here not hardware) and the connection maybe (multiple?) gigabit ethernet. The result would theoretically be lower than 1.6 million but we need to show FreeBSD can scale in practical tests like these. Results from a test like that will have the power to change vendors' minds from trying to run IIS and MS SQL for a high volume site.

What are IP "Connections"? AFAIK, the transport layers can have connections, but not the network layer. IP has datagrams. I did RTFA, but there's not a whole lot of context in that message, and I was too lazy to go read the whole thread. Are they just talking about TCP connections, or what?
...to take on heavy server loads.
What did happen to the *BSD Box when reached the 1.6 millon of connections?, did he dyed?, did it just stoped accepting connections due low resources? why he wasn't able to pass the 1.6millon of IP connections when we can count as much 4294967296 differen IPs for a network?

I would like to claim that I have the world record for a one minute load average on a FreeBSD machine.

Any contenders?

I wonder if the 64-bit version of FreeBSD would be able to improve upon this, since it can access more memory.
Ouch! The truth hurts!

No one on slashdot uses that phrase correctly just like everyone on /. thinks alot is a word.

Insightful, yes.
But what of the idealists? Perhaps we don't care how long we live, but just to spread the truth! (e.g., that conventions are found in a dictionary, but ignored out of arrogance.)
This has its problems, of course. For example, how do you really know if you get through to someone? And then, after a while, should you care at all? If you question someone, you are consistently attacked for being hubristic; when in reality you really can't fathom what they're thinking, yet they know they know everything.
There's a point at which clear speech doesn't work anymore, but establishing clarity goes a long way to extending its possibilities. Sarcasm, meta-funny jokes, and textbook "trolling" can make anything mean anything else. Acknowlegding this is the first step in making one's intent clear. But how do you make people desire clarity? I sure as hell don't know.
Perhaps unfortunately, I can't help but realize that people are wrong most of the time (I think slashdot is fairly representative of real life s:n, believe it or not). That's what I know. I know very little else.
If everything were not a personal attack on someone's faith in their own knowledge (which is humourous: they proclaim to posess the knowledge, yet refuse to show it for fear of being proven wrong, yet defend it anyway), then... well, that would be love.
The given link for Terry's message seems to be broken.

I know what TGP references for content, but what does that particular abbreviation stand for? Looking it up in google brings a lot of content links, but no definitions.
Personally, I would be very interested in seeing how well the machine in this record-setting example handles an attack of the type mentioned in the above referenced article.
