EFnet Paralyzed By Vulnerability

nenolod Re:Full disclosure takes a hit (156 comments)

He did not disclose it, the person who disclosed the vulnerability did so in a public space for development discussion on charybdis. Once it was out in the open, we quickly jumped into action to start mitigating it across all fronts including EFnet. The ratbox developers were notified at least an hour before the exploit was unleashed, with a patch to deploy and everything, so really we did everything we could possibly do to mitigate the possibility of fallout.

Once people started running the exploit on EFnet servers, there was not much we could do, other than get the ratbox devs and admins regrouped elsewhere to coordinate getting things patched. I would say that things mostly went down as well as could be expected given the situation...

EFnet Paralyzed By Vulnerability

nenolod Re:Stop writing things in C/C++ (156 comments)

The problem isn't performance as much as it is accessibility. Almost every UNIX system has a C/C++ toolchain installed, not so much with Lisp, Java or C#. Also, C and C++ are generally the lowest common denominator for contributors. Almost everyone knows a little bit about C, not so many people know about Lisp (which is a travesty in and of itself, but not my problem).

MUC is extremely inefficient though. There is no multicast notion in XMPP, so MUC works around this by sending duplicate messages to each user directly.

EFnet Paralyzed By Vulnerability

nenolod Re:EFnet is already paralyzed (156 comments)

EFnet does not provide NickServ or ChanServ, which is a common criticism of the network. Due to not providing centralized authentication or channel ownership services, the other aspects of the modern IRC protocol mostly do not apply.

EFnet Paralyzed By Vulnerability

nenolod Re:C strings strike again! (156 comments)

This was a NULL-pointer exception, not a buffer issue. But I do agree that it makes more sense to invest in building IRCd software which is written in string-safe and pointer-safe languages. Mozilla's rust language, for example looks promising for use in IRCd. The main thing is that we need a language which provides scalable data structures, as servicing IRC messages involves many data lookups.

However, it is easier for most people hacking on IRCd to just pick up a 2.8-derivative.

EFnet Paralyzed By Vulnerability

nenolod Re:EFnet is already paralyzed (156 comments)

There has been a lot of work in this area with a few projects now... Microsoft's IRCX, then IRCNEXT, IRCPLUS and now atheme.org's IRCv3. IRCv3 is becoming the defacto standard at this point, supplanting the traditional IRC protocol, as almost all vendors that are noteworthy have adopted support for revision 3.1 of the protocol already.

Both Atheme and Anope can be interacted with via RPC from scripts allowing for web integrations. Also, there are immersive web clients which provide a lot of useful metadata to clients.

you do not know what you are talking about. the actual bug was disclosed in the IRC channel for charybdis. there was no "bug report."

Hosting Giants Teaming Against Small Businesses

nenolod Re:Actually (163 comments)

They have a bandwidth pooling agreement.

As for SoftLayer, their goal is quite simply to generate more sales channels. That's why most of the big DCs tolerate reselling and even encourage it. Like I said, the business model works to a certain point but then totally breaks down as the risk gets higher.

Except they don't. Because it's impossible.

Bandwidth isn't something you can just oversell without consequence; if you have a massive overage from people actually using what they are paying for then you are probably out of business.

See, I think what happened here is that 100tb had a massive overage and found out that SimpleCDN was one of their big players and they are frantically trying to get the big guys off their bandwidth pool so that they can hedge against the overage while already having SimpleCDN's money. This would fit into my projections for the original business model of 10tb.com before they became 100tb. At least with 10tb there was some sign of it being at least somewhat realistic; with 100tb there is no way.

Or... let's think of it this way:

Say you buy a server from 100TB for $201.95/mo (baseline server with 100TB bandwidth). This works out to being ~303mbps 95% on a typical burst pattern (and likely much higher for streaming traffic!). The server probably costs $100/mo just to run, leaving $101.95 for bandwidth (in this example we're not making any profit mind you!).

This means that your ~303mbps 95% breaks down to $0.33/mbps.

Not even BANDCON can hit that price point and they go really, really low.

This business model does not make sense to me. There is very high risk and I see no way that they can hedge against overages if everyone actually opens up and uses all of their 100tb allotment. Maybe they are paying by GB instead of mbps but that makes no sense because then SoftLayer would be holding the bill and frankly I don't think they are that stupid.

So no, it's not possible to make up profit through volume on this when you keep in mind the risk you are hedging. It's just too much of a gamble for any sane business operator to even consider.

nenolod Re:Unfortunate But Wait... (163 comments)

UK2 also confirmed to us many times that their business model fully supports 100TBs of transfer, and SimpleCDN has been utilizing these servers for many months now without problem.

Why didn't you look at their business model directly? What you were getting would cost at least 5 times more directly from SoftLayer...

You know, posting followups on every site where this is being discussed makes you look like less of a victim...

I would like to hear what ditlev has to say about this, as the numbers behind 100TB never made any sense to me as a business model... how can they make any money selling for $10000 what SoftLayer directly charges $50000 for?

Things To Look For In a Web Hosting Company?

nenolod Re:No, *avoid* DreamHost... (456 comments)

Hurricane Electric sucks and is down more than you think. I used to colocate there, and it was a total disaster. HE is a provider which does not have a reliable UPS system (although they tote pictures of car batteries on their web site), infact their ATS failed (caught fire, I have been told) last year on two different occasions... which lead us to leave.

I would suggest looking into a different provider if you are using HE for anything.

Actually, the worm also exploits some vulnerabilities in the HTTP servers in some of these models.
