If an application server (written in NodeJS) were to become extremely popular with say 1000 times more traffic than FaceBook, how would the load be spread across multiple servers?
Would all traffic need to go through an initial load spreading server? How would the load spreading server deal with...
@Iain huh? oh, I see. I set it wrong when I removed the santa hat. I used the one you did here because I thought this other didn't look as good at the 16x16 size. (:
And I'm talking about "The Big Sleep" and not "you are a ninny"
@Ward So this guy wants to make his Windows box a hotspot, but is having port troubles. I write out a huge response about transparent proxies and rewrite rules. He comments back: "I am trying to mess with connectify only for my android phone, i rooted my phone tried tunneling, proxy softwares etc, but none is letting me activate my phone."
I have a 100 megabyte (MB) file, and I have a 30 megabit/s (Mb) dedicated bandwidth speed on my server. How many people could download this file at the same time, with acceptable speeds?What megabit/s do you recommend for moderate-to-high traffic?
Moving to a new office soon and we will hire up to 20 people. Number of devices might be more than 20.
I'm not a networking expert so I'm not sure what type of equipment to get. I can buy a simple Linksys router for less than $100 and install ddwrt on it, but will that have stability issues serv...
It doesn't sit completely right with me - I'd love to answer a lot of cisco questions with 'hey, I can do this for you if you pay me', but I don't feel it's quite right for the site
@Aaron Yeah, I think in that case it was warranted because the OP was so far out of his depth and so clueless.
"I needs tha 'puters 'n' tha networks. What to buy?"
If he had shown some cluefulness, perhaps that would have been better. Instead, he tipped his hand as being a freeloading luser.
@Aaron So yes, if you find yourself dealing with a freeloading luser who has no business touching Cisco equipment but wants to make it all work, toss your contact details into a comment. =)
I'm thinking this topic will probably end up in meta though.
Assuming the following scenario:
Server A has IP address 192.168.254.1
Server B has IP address 192.168.254.2
Server A runs MySQL configured with bind-address = 127.0.0.1
Question:
How can I use iptables on Server A to forward traffic originating from 192.168.254.2 and hitting 192.168.254.1:330...
@WesleyDavid Yeah.. probably. I initially commented because I was hoping he had a better justification for doing it that way.
Well, I'm gonna run and grab some food. I'd feel like a jerk leaving that last comment then immediately leaving the "you're doing it wrong" answer - if someone wants to steal it, I'm nearly rep-capped for the day anyway.
Oh wow, now he left a comment accusing me of being unhelpful when I told him exactly what to do (just in fewer words than a full answer). Yeah.. walking away from that one.
I wasn’t looking for a flame war, I was looking for an answer. Since @ShaneMadden thinks I’m Doing It Wrong™, I deleted the question, and I will re-ask it using what he said I should be doing. The core of my question was how to correctly use iptables. I don’t know, so I’m asking.
@abrahamvegh We weren't looking for a flamewar either, it just seemed like things went from "How can I...?" to "You shouldn't..." to "OMGWTF WHY U SO HATEFUL?!"
@WesleyDavid Naturally, but I don’t think my attitude was “why so hateful?!”, it was “we’re both spinning our wheels trying to get what we want, so let’s knock it off”.
This question on Security.SE made me think in a rather devious way. At first, I found it to be rather poorly worded, imprecise, and potentially not worth salvaging. After a couple of days I started to realize exactly how many times I’ve really been asked this question by well intentioned, and often, knowledgeable people. The real question should be, “Is there a recommended set of firewall rules that can be used as a standard config?” Or more plainly, I have a bunch of systems, so what rules should they all have no matter what services they provide. Now that is a question that …
@abrahamvegh Okay, fair enough. I think perhaps the personalities here tend to be of the more direct variety which is a polite way of saying "we could use some softer edges"
@WesleyDavid I know downvotes aren’t personal, but thinking I’m a noob and won’t notice people talking about me in the chat room could be misconstrued as personal. ;)
@abrahamvegh But yes, do stick around. You'll get an answer to virtually any question, it just might not be packed in rose petals or be exactly what you had wanted. I've got the battle scars myself to prove it. =)
@abrahamvegh And yes, I know that the chat room isn't private and that anyone can see it. I don't type things that I wouldn't be okay with someone seeing... which will probably leave a track record that outs me as being kind of a dick. =P
I'm getting better! Really!
@abrahamvegh So in direct reference to me calling you a snowflake, that was my impression of deleting your question. It would have been answered and answered well sooner or later, but the question being deleted so quickly and given the comments that were typed out, it gave me the impression that you had taken your marbles and stormed home.
And no, my impression is not worth much more than a handful of dirt. And not very fertile dirt either.
Oh, the humanity. :) Have no fear of scaring me off. I’m a longtime SO user (#78877, fun fact), and equally longtime SF user (#1325). I’m keeping my marbles, but I’m in the for the long haul.
I had a 4 digit /. UID back in the day... Then I forgot about /. for the longest time and couldn't remember my password; didn't have access to the e-mail address anymore; so it's gone. Now all I've got is this lousy 6 digit one.
I ragequitted /. after someone specifically told me in a comment my opinion was worthless because I had a fairly recent UID (regardless of the fact I'd lurked on /. for about 5 years). I know the site is full of trolls and my opinion probably was worthless, but it was the whole reason they gave.
I remember when people used to complain about articles that were unworth of Geek News (slashvertisements); it would happen once a week, sometimes more! Now every other post on there is a slashvertisement.
I used to like digg until they had their implosion a year ago or whenever it was and my account got crosslinked with someone else's and I just gave up on it
I can't remember. The crash screens in Debug Builds are a different color, purple IIRC. The crash screen for the Windows loader program (having a brain fart and can't remember it's name) is Red, I've seen that one before.
On Server Fault, it's definitely "How do I host my server from home":

@ChrisS and someone was doing some traffic engineering and said something about getting rid of all the black lines, so someone promptly said 'why's it always gotta be getting rid of the BLACK lines'
I love working at a place where political correctness isn't a priority
@ChrisS There have been a shitload more of them lately. Usually nginx and re-writing. But back when I wrote that answer, it was how to host from home. And I haven't even updated that list in a long time.
That was Windows Server 2003 R2's excuse and it's a real slap in the face. You'd boot it up and it would say "Hey, listen, this OS is a bit shit and not really secure, so I'm going to disable all the interfaces until you've installed the entire CD #2 and configured all your firewall rules"
Which of course, nobody ever did and just hit continue anyway.
Not just that but because all the interfaces are disabled you need to do it all via the console, and who actually works on the console these days? With KVMoIP and virtual machines, working in the console is a pain in the arse for remote machines (laaaagggg)
It's even more of a pain in the arse when you actually have to go to the console because that involves actually standing up and moving somewhere else
@JamesOGorman For security... You know RSA got pwn3d earlier this year because their firewall did Default To Allow while booting, approximately 2 minutes of no firewall => owned.
(I just wanna point out I'm one of those hot lesbians from the "movies", not a lesbian like 99.9% of real lesbians, who are usually have a mustache and a shaved head)
@abrahamvegh Hey, sorry for the overly-terse comments on your question; I should have just done a "do it this way instead" answer with the steps from the start.
I've setup an IVR to pickup up incoming calls to allow them to enter an extension or press one to be dropped into the ring group for our office. The only issue is Asterisk isn't playing the WAV/MP3/GSM audio file I upload. Using a default recording works , I'm not sure why mine won't. I also know...
all right, exim can go piss off. I setup dkim all nice and happy-like. Tested it and it worked. I then leverage puppet to push the config to our other exim server and... voila, no longer works.
Oh asterix. I know the price is right and all that but whenever I talk to someone who has deployed it I come away with the impression that "making the utter dross in the PBX market sound good" was a design goal.

SEO-wise, if you make a typo or configuration goof, google will record that and if Mr. Public winds up searching for that error, voila, he has a lil more info to go on.
Definitely one of the things I seriously dislike about the asterisk community is all these gui config tools, it makes it VERY difficult to help diagnose someone's issue without having familiarity with the gui and have access to their servers.
