Eloquence writes "infoAnarchy reports that Coral, a peer-to-peer webcaching system, has gone into public beta. Currently the Coral node network is hosted on Planet-Lab, a large scale distributed research network of 400 servers. You can use Coral right now by appending "nyud.net:8090" to a hostname.

No, it really is down, at least from here:

Windows:
C:\>ping slashdot.org.nyud.net
Ping request could not find host slashdot.org.nyud.net. Please check the name and try again.
Linux:
~$ping slashdot.org.nyud.net
ping: unknown host slashdot.org.nyud.net

~$dig slashdot.org.nyud.net
; <<>> DiG 9.2.1 <<>> slashdot.org.nyud.net
;; global options: printcmd
;; connection timed out; no servers could be reached
Seems their nameservers have some kind of problem. I am in the Midwest, going through an AT&T OC3 (everything else works fine from here; it's not a local problem). It works OK when I check from our California-based servers that peer with Mae West, however.

"Invalid domain name in packet" (5, Informative)

Anonymous Coward | more than 9 years ago | (#10100090)

It really DOESN'T work for a lot of people.

The problem is that it doesn't seem to be compatible with Microsoft DNS severs. Below is a copy of the DNS log when I issue a query here, on my LAN which has a Microsoft DNS server running on Windows 2000, which then forwards through the University of Wisconsin. You can see that at the end it says "The DNS server encountered an invalid domain name." Perhaps someone who knows more about DNS can tell where the problem is?

Google doesn't covert links in the cached page, you need to dig out cache of every page you want to visit.

Re:Google (1, Interesting)

Anonymous Coward | more than 9 years ago | (#10100093)

Why does the /. effect still exist.

I can understand back in the day where a 300MHz computer was expensive; and I can understand why a 128K hosted-at-home site won't survive one. But c'mon, guys - in this day of fast CPUs and cheap bandwidth, how can your servers _not_ handle a few more users. Is everyone using .NET or Java bloat to make up for the advances in hardware over the years?

PS: Yes, i've survived a slashdotting, with 300MHz sparcs. No, it wasn't a big deal. A much bigger event was a nationwide radio show that had its peak traffic concentrated over 2-5 minutes, unlike /.'s gradual half-hour of increased traffic. The Howard Stern effect (if he mentiones sex) and the National Public Radio effect (if its an interesting story) each put the /. effect to shame over 1-minute timeframes.

you can ensure that your readers can still access a certain web page or files, when the multitude of readers would otherwise overload the website and make the content unavailable.

well apparently all html content, including files, will be cached. this is a great way to get around downloading from snail-pace sites, (although i will be checking md5sums)

Not too good for websites (3, Insightful)

chrispyman (710460) | more than 9 years ago | (#10099881)

While their system would be pretty good (supposing it can withstand a slashdotting) for cacheing large files, it's not very useful for websites. Websites usually have lots of additional images, links, and whatnot, and as is currently, the system doesn't rewrite URLs.

Re:Not too good for websites (4, Informative)

Coneasfast (690509) | more than 9 years ago | (#10099909)

links should be (and usually are) relative, eg:

img src="img/logo.png"
not:
img src="http://slashdot.org/img/logo.png"

or whatever so this shouldn't be a problem

Re:Not too good for websites (1)

crazney (194622) | more than 9 years ago | (#10100047)

Some web sites have images hosted on another machine. The company I work for did that for some time, as bandwidth was cheaper on our image machine but we had less control over it.

moosesocks (264553) | more than 9 years ago | (#10100194)

Slashdot does not use .PNG for its graphics, but rather uses .GIF

As this is an obvious contradiction to the views of the site's editors and readership, I once emailed Malda asking him why he used GIFs.

He said "not to confuse his reader's interests with his own interests".

rsilvergun (571051) | more than 9 years ago | (#10099907)

as will ISPs if it takes off. Right now with bandwidth usage centralized it's pretty easy to bill for it. If you decentralize it with p2p via millions of always on unmetered clients/servers it gets hard, if not impossible. I kinda hope it doesn't take off, since if it does it could end unmetered Internet access...

Re:Hosting companies'll hate this.... (-1)

There has been something called FreeCache [archive.org] for some time already. It helps with big files (over 5MB). But of course, why use it when you can fuck people's servers instead? Sometimes it is more about will than technology.

me thinks not P2P (2, Interesting)

rob101 (809157) | more than 9 years ago | (#10099934)

This is a Content Distributon network of cooperating servers colloborating to exchange information and 'level out' excess demand by distributing reqiests among n servers. Like Akamai's EdgeSuite. based on a quick read of the front page. The providors of content in their network are never the consumers if content. thus i don't know why they call it peer-to-peer? anyone?

Re:me thinks not P2P (0)

Inominate (412637) | more than 9 years ago | (#10100153)

It's not p2p.

It's 'distributed'.

Peer to peer implies that the users of the service are the ones supporting it's existance.

bigberk (547360) | more than 9 years ago | (#10099937)

Some friends and I have an approx 10 MBytes application we want to distribute over the Internet, looking into hosting costs we see that it would cost us a bundle. So does coral let us serve our file to a slashdot-like crowd without breaking the bank?

Pillager (6026) | more than 9 years ago | (#10099963)

There's a better solution for big files - it's called bittorrent [bitconjurer.org] . It's nothing new, and it regularly transfers gigabyte size files for a fraction of the senders traffic.

An interesting question. It would seem feasible only to serve up the full page when this is requested by a cache server, in all other cases just returning a redirect.

If this actually proves possible, and no way of blocking it is found, it may kill the project stone dead.

That's very cool. (1, Interesting)

It isn't P2P web proxy, it's just "big pipe"-based distributed one. Supposedly a great way to prevent slashdoting (just use http://freecache.org/http://mytinysite.com instead of http://mytinysite.com and everything goes from the cache, tiny site receiving only header requests to chceck if the document hasn't changed in the meantime) it's hardly known, way too quiet as for a project that useful. P2P may be faster and cheaper but certainly less reliable...

Er... no... from the site:

"Please note that you cannot submit a whole site to FreeCache as in http://freecache.org/http://www.rocklobsters.com/ This will not work as only index.html will be cached. You have to prefix every item that you want to have cached seperately."

As I understand it, Freecache refuses to cache small files anyway; I think the minimum was 5Mb.

Not a good solution (2, Informative)

pyrrhonist (701154) | more than 9 years ago | (#10100210)

From the FAQ:
What files are being served by FreeCache?

FreeCache can only serve files that are on a web site. If the link to a file on that web site goes away, so will the file in the FreeCaches. Also, there is a minimum size requirement. We don't bother with files smaller than 5MB, as the saved bandwidth does not outweight the protocol overhead in those cases.

Only the top page? (4, Interesting)

All the links on Slashdot have the format
<a href="//slashdot.org/blahblahblah">
so that they will always link back to Slashdot. Most websites just use "blahblahblah" or "/blahblahblah" for their links. For example, links on google.com.nyud.net [nyud.net] are fully functional.

Is it possible to combine this with bittorrent (2, Insightful)

No, because... (1)

Only caches main server files (1)

AIX-Hood (682681) | more than 9 years ago | (#10100009)

I was playing around with this the other day. I tried it out with my filerush.com page which has the main html, but all images are loaded off a second images.domain.com server. Coral will get the main server's files that match the origination URL that you passed it, but will skip all files that are sitting off another server. So basically it'll handle all relative links, but no hard links to other sites. It would be killer if they somehow made it configureable in your browser's proxy settings.

Notice the random question at the bottom of the page.

Then go here: http://www.newberrycollege.net.nyud.net:8090/ [nyud.net]

The question is not randomly generating. They should have some checking for this such that if the data varies by the second, that it does not cache the page or invisible frames the HTML and filter the content it can cache.

Bleh.

It will work in certain cases, but generally I am not that happy.

Re:Doesn't Work. (1)

mothz (788133) | more than 9 years ago | (#10100120)

I'd say the vast majority of websites vary slightly each time you reload them, due to ad content. Granted, sites with ads on them should probably be big enough to avoid a minor slashdotting, and they probably wouldn't want their pages to be cached anyway, since advertisers typically pay based on the eyeball count.

It will fail, because business will want it to. (2, Insightful)

CFD339 (795926) | more than 9 years ago | (#10100089)

This system fails because most commercial sites, and many others, will lose the ability to track web usage for site tuning and marketing response. Sites will be built -- if need be -- with specific settings or configurations to confound the coralling of their pages.

Its a noble goal, but ultimately will go the way of the video phone -- which apart from conferences planned in advance, remains a novelty dispite perfectly adaquate technology -- nobody wants a suprise video call because nobody wants to be a 50's housewife who's self esteem is tied to the cleanliness of their floors and their ability to have perfect hair and a matching necklace and top all the time "in case someone calls".

If people don't want it, it will fail regardless of how well done.

Stephonovich (601356) | more than 9 years ago | (#10100167)

[subject]

Although I agree with others, it doesn't really compare to FreeCache. I still wonder why that never got much attention. It's an insanely great idea. Ah well. Between that, Corla, and BitTorrent, you never have to worry about /.'ing again when you submit your tiny personal site.

In other news (for the morons who continue posting and whining), you can still remove the it prefix from the /. URL, removing the fugly colour scheme. And there was much rejoicing in the land.

Is this the end (1)

teamhasnoi (554944) | more than 9 years ago | (#10100172)

of the /. effect?

No.
Safari can't open the page "http://slashdot.org.nyud.net:8090/" because it could not connect to the server "slashdot.org.nyud.net".

I believe there is a term for this.

I've tried http://slashdot.org.nyud.net:8090/ in several different browsers, and the page only brings up gibberish. Just like when you hit View Source on a jpeg or some binary file. What's the deal?

Kindgott (165758) | more than 9 years ago | (#10100190)

I don't know about anyone else, but when I viewed slashdot through the cache, my login was no longer in effect.

If this is a consistent problem across the board for page caching, I can't see it being useful for sites that use logins. And I'll be damned if I'm going to use the login link in the cached page.

Possible problems with this scheme... (1)

slashname3 (739398) | more than 9 years ago | (#10100219)

I believe there are couple of problems with this scheme.

1. The site owner will not be able to monitor hits on the site.
2. This appears to work for static pages but it won't work with dynamic pages ie. php.

I have to believe that ISPs that provide web services would find their revenue reduced since they would not see all the hits on the site.
