Would Facebook or Google benefit from having been on RackSpace or EC2 from the start, or is it cheaper or otherwise beneficial for them to maintain their own datacentres?
We need to get Jeff to add a feature to the serverfault site. If a user with 1000+ rep asks their first question on serverfault they need to be forced to the visit the serverfault.com/questions/how-to-ask page....
@GraceNote, It isn't that bad really, we just occasionally see questions like this serverfault.com/questions/311421/…, were the person is not the sysadmin. They problem is almost certainly something to do with their local software, or a local firewall... Since they are not the admin they cannot provide any useful details like a tcpdump/logs/etc.

it's not so much that they migrate crap, I 'm just not sure they have a 'migrate to somewhere other than SF' button or mentality - "Oh I can't code this answer, must be SF"
@GraceNote well one that I participated in, that resulted in us whipping out our statistical penises and pointing at eachother's crap migration records...

I suggest looking in Active Directory to see if the IP address correctly represents the DNS name you are connecting to. The IP address works because it is most likely a DNS issue like Mark M stated.
Are you implying that there's some kind of a link between talking about male genitalia and moderators? Because that might get you in trouble with the modhammers.
After listening to the last podcast for SE I was going to ask Kyle or Zypher if there was a possibility of getting a guest on that could talk about running a business using the amazon cloud. They mentioned someone before with the question of running the SE servers as cloud servers versus how they do it now, but they had talked to someone at a conference about how they run their servers through the cloud and have all sorts of issues.
I thought it would be interesting to hear about that kind of IT setup.
@MarkM: I thought they were eyes for a Simpson's character.
That sounds very unlikely to me, but just to be sure:
Can a member of 'Domain Users' join a computer to the domain (granted that he has the local administrator account)?
The instructor said it, and it sounds very wrong.
I tested it and I got 'Access denied' when I tryied to supply a regular user...
I swear I did that over two years ago, but two new machine accounts just popped up in my empty Computers OU and a luser is listen in the ACL for the object
Hm, it was set to the default (10). I'm losing my mind.
Just installed Windows 8 Preview, and can't figure out how to get to Shutdown/Restart option in the Start menu.
Clicking on start menu brings up the "Start Screen", but Shutdown/Restart options are not there.
Had to use command prompt to shut my box down.
Ideas?
Use one of those download accelerators that can use multiple connections. Wouldn't even have to bond the NICs... Not really what you're asking for, but an idea.
@Zoredache you can configure bonded interfaces that way in Linux and FreeBSD - the hard part is breaking up the packets going out the virtual (bond) interface and allocating them amongst the physical (ethernet) ones. IDK if anyone has adequately licked that yet....
I have never used it, but I don't believe that aggregating via MLPPP has that problem, and across a MLPPP tunnel you can actually get the total capacity.. I am kinda curious if anyone had every created a switch that would allow you to build a MLPPP connection with lots of interfaces.
@voretaq7, I know that Linux can do some spreading of the load, but everything I have read that you get at best n+n*0.5 where n is the capacity of a single number of the group.
So for a pair of 1GB, you usually max out at around 1.5. For a 3 1GB interfaces you get about 2GB.
@voretaq7 Packets go out of order and cause all sort of interesting problems when you break the session-NIC link.. To my knowledge nobody's come up with any good solutions.
I assume the bonding module is another college CS project that somehow escaped into the wild, so randomly spewing packets would probably outperform it.... (I'm sorry, was that mean?)
The last bit at the end here he said this so the full throughput can be used by one single connection makes me suspect that. Which leads to my answer, that I think he can't actually get what he wants.
@Zoredache The wording that he uses, "parallel connections", matches the wording in iperf's docs for multiple threads - which is why I think he's got no special transit. But the aggregation question is much more interesting ;)
I would like to make sure I understand this correctly.

<insert retelling of the parable of the phone company here> And by breaking up Bell we fostered competition among many local carriers, and prices fell.... what? over 1000 times more expensive? even when adjusting for inflation? Faaaaaaaaaaaaaaaaaaaaaaack!
If as an IT professional you find yourself consistently using Microsoft Windows, you may be interested in the 2011 TechMentor conference happening in Las Vegas on October 10th through the 14th. There are 8 tracks and over fifty sessions to choose from. There’s even a VMware vSphere track tucked in there as well. However, the [...]
@ShaneMadden: I'd find it hard to believe they're storing FTP credentials in cleartext, if only because crypt or md5-based password storage has been the norm in the *nix world for so long. I wouldn't say it's impossible, but it seems improbable.
An over-the-wire compromise seems a lot more likely.
@EvanAnderson Sure - just very interesting that the victims of this stuff are all hosted on GoDaddy. Maybe a MITM happening at one of their upstream providers. All the limited interaction I've had with them, though, they've seemed pretty amazingly inept.
@ShaneMadden: That's what I'm thinking-- an upstream of an upstream with owned boxen. You definitely get what you pay for w/ GoDaddy. In an early 2000's Internet I can see using FTP but today they really should mandate that their Customers use SFTP or WebDAV over SSL and make FTP an option that you can turn on only after being told about the risks.
@EvanAnderson OK, true, but seriously - can someone kill FTP? It's obviously unhappy, so why not finish the job and put it out of my misery. Take away its port assignments and send it to a farm upstate!
@ShaneMadden: There is some elegance to the idea of third-party transfer in FTP that the data / control separation enables but, in general, I'd agree that it's a PITA.
@ShaneMadden: I haven't been exposed to it in a practical application to have any feelings about it, other than it reminds be vaguely of BXXP/BEEP... (and, BTW, BXXP was a much cooler acronym than BEEP).
The inbuilt multihoming support in SCTP is damned cool, though.
I think Vint Cerf has actually apologized for TCP not having multihoming capability.
You know what would make killing sftp a lot easier? If someone could come up with an sftp daemon that supported per-user chroot without the permission weirdness or hacks that are required to make it work.
@Warner: Yeah... that was a little frustrating. My wife scheduled time off of work for a family camping trip and I, stupidly, hadn't put LinuxFest in our shared calendar. Per our schedule conflict resolution policy she won. I had a great time camping, though.
St. Ignace, MI-- on the southern tip of the upper peninsula. The weather was awesome-- sunny, cloudless, low 70's with no humidity. It was great.
The drive up from Dayton on Thursday was really crappy until north of Detroit when, suddenly, the rain stopped and the clouds opened up. Driving right to the edge of the front was wild... we were looking up ahead saying "I think that's the sky up there... and there's this glowing thing in the sky. What's that?"
One last bit of summer... >smile<
@Zoredache: The first time I tried to do a per-user chroot SFTP server on Linux I was really surprised at the gyrations I had to go thru. Craziness.
How was LinuxFest? Once I learned I wasn't going I didn't even bother much looking at the list of speakers.
Ahh, crap. Bradley Kuhn was there. I've wanted to hear him speak for awhile. >grumble<
@Warner: "Rustic". In a tent, but w/ running water, bathrooms, etc. Basically an excuse to make fire and cook things over it. >smile< I just looked over the speakers list and it looks like I missed some good stuff.
We haven't gone as much as we'd like this year. A normal year is 5 - 7 weekends, but life has been crazy this year and it looks like we're going to have 3 extended weekends for our entire season. I interrupted my consecutive Server Fault visit days (at around 180) over the weekend and, coincidentally, the interruption 180 days ago was because I was camping... >smile<
We've got one more scheduled in October in western Indiana. I'd really love to camp in the winter but I can't get my wife interested in it. Too cold, she says. I have really fond memories of camping in the winter back when I was a kid (when I was a Boy Scout... >smile<).
Did you get the sysadmin position you were advertising filled?
That's got to be frustrating, not being able to fill the positions. If I knew anybody that I think was a good shot I'd pass along a name, but everybody I know who is competent is either in a full time gig or enjoying freelancing too much not to.
Market's just tough right now, most people don't want to move. People were moving earlier this year but when the economy started to slow down again, it changed.
If you are going to ignore the subject and ask a question, please don't be so annoying to ask to ask a question. This is chat a asking to ask just wastes time...
