  • Is that why the website is called serverfault <g>

    - by bmullan
    Couldn't help it... just trying to be funny... when trying to save my profile I got the message from your website see below. Or is that an "initiation" ha!

  • Is the difference between superuser and serverfault basically when you can do a power cycle?

    - by wag2639
    Generally speaking, aren't there a lot of problems that can be fixed with just a simple power cycle? Especially with Windows, a reboot will solve the problems (at least temporarily)? So, would this be the difference between serverfault and superuser? Generally, where as a superuser might just be annoyed by a restart/power cycle, a sysadmin cannot because its a critical system or otherwise production box?

  • ServerFault Wiki: How does Subnetting Work?

    - by Kyle Brandt
    How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Serverfault gets lots of subnetting homework questions, so we could use an answer to point them to on serverfault itself. If I have a network, how do I figure out how to split it up? If I am given a netmask, how do I know what the network Range is for it? Sometimes there is a slash followed by a number, what is that number? Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different? Someone mentioned something about knowing binary for this? Not looking for links to other sites (unless maybe you have one post with a bunch of good ones). I already know how to subnet, I just thought it would be nice if serverfault had a generic subnetting answer.

  • What's with the unicorns?

    - by Ward
    And don't tell me this is meta and should only be discussed over there. It's happened here, there should be an answer here. I guess that in UTC it's April 1, but it's a huge distraction.

  • very slow bridge detection

    - by deddihp
    hello everyone, I have setup some bridge interface with 4 ethernet port. My problem is, when they detect some network topology change, the bridge really need a lot of time to have done it. Is there any solution, so the bridge can detect topology change faster ? thanks.

  • What's the best way to Notify network users of outages or maintenance

    - by Dubs
    There are times when one of our applications is down for maintenance and we'd like to let our users know about it before they start flooding our help desk with calls. What's the best way to notify our users of an event on the network? Some users are on our intranet, while others log in from the Web. Is there an application they can install to which we can send notifications messages? I'm interested to hear what others have come up with to address this requirement. Thanks!

  • 2 servers on 2 networks in same office

    - by irot
    Hello Gents, My office doesn't have a "server guy" in employ, so I'm stuck with having to fix server issues for now. There are 2 servers in our office, both are file/web servers only accessible via LAN. They are currently on the same network, so no issue there. Problem is, we recently got a static IP to use, but it's with a different ISP, so now we have 2 routers in our office. I would like to open one of the servers to the public as a web/FTP server. But if I hook a server up to the new router, users will no longer be able to access the files shared on that server (because they're on different networks). How can I go about making one server accessible to the public using the static IP line, but still able to share the files on it to the users connected to the other network? The server I want to make public is running Windows Server 2008, the other server Windows Server 2003. And as far as I know, IP addresses are assigned by the router. I'm just a developer, don't know much about networking. Thank you in advance.

  • All comments get marked as spam regardless (Wordpress MU)

    - by meds
    Everyone (besides me) who comments on another persons blog gets marked as spam when they comment on other peoples blogs. When they comment on their own its fine. Might be related, I've installed reCaptcha and have disabled it for logged in users yet everyone who is logged in still sees it, I don't, and incidentally my comments don't get marked as spam. I don't have akismet or hashcash or any other form of spam filtering turned out (with the exception of super captcha for registration). Any idea what's wrong or where I should look first?

  • How many copies of files are needed by video server?

    - by Trilok
    A quick question. How many copies of the same movie are kept in a video server (a video streaming server)? Suppose a particular video is at max requested by 1000 users at the same instant of time, how many copies would be sufficient so that parallel streams can be provided to each user? Ideally 1 copy would solve the purpose, but what is the optimum number keeping the bandwidth and simultaneous access in mind?

  • How do I set permissions on a Server 2003 folder

    - by Richard210363
    Hi There, In my part time position as entire IT department at my Office ( I'm a MCSD developer normally ) I have been asked to change a shared folder. Only I don't really understand all the Shared / Security options. I have a folder that must be accessed by 2 people in the company (and no one else). They both must have read/write/edit and change access. They must be able to read/write/edit each others files; existing or newly created. Should be easy but I'm a bit overwhelemd by all the choices. What should I set? Thanks for your help richard

  • Setup a proxy (Not reverse proxy) using Varnish/Squid.

    - by shabda
    I need to setup a proxy server where we can request remote urls and get them served locally. Basically what I need is mysever:8000/varnish/serverfault.com get me serverfault.com served from my local varnish or myserver:8080/squid/serverfault.com get me serverfault.com served from my local squid. (Both should cache the site for 24 hours) I am evaluating if Varnish or Squid will be a good choice for it. Which one will be a better fit? How do I do it. Links to tutorials would be good.

  • How much network latency is "typical" for east - west coast USA?

    - by Jeff Atwood
    At the moment we're trying to decide whether to move our datacenter from the west coast (Corvallis, OR) to the east coast (NY, NY). However, I am seeing some disturbing latency numbers from my location (Berkeley, CA) to the NYC host. Here's a sample result, retrieving a small .png logo file in Google Chrome and using the dev tools to see how long the request takes: Berkeley to NYC server: 215 ms latency, 46ms transfer time, 261ms total Berkeley to Corvallis server: 114ms latency, 41ms transfer time, 155ms total some URLs if you want to try yourself: http://careers.stackoverflow.com/content/cso/img/logo.png (NY, NY) http://serverfault.com/cache/logo.png (Corvallis, OR) It makes sense that Corvallis, OR is geographically closer to Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I perform the same test to the NYC server. That seems .. excessive to me. Particularly since the time spent transferring the actual data only went up 10%, yet the latency went up ten times as much! That feels... wrong... to me. I found a few links here that were helpful (through Google no less!) ... http://serverfault.com/questions/63531/does-routing-distance-affect-performance-significantly http://serverfault.com/questions/61719/how-does-geography-affect-network-latency http://serverfault.com/questions/6210/latency-in-internet-connections-from-europe-to-usa ... but nothing authoritative. So, is this normal? It doesn't feel normal. What is the "typical" latency I should expect when moving network packets from the east coast <--> west coast of the USA?

  • iptables rules to allow HTTP traffic to one domain only

    - by Emily
    Hi everyone, I need to configure my machine as to allow HTTP traffic to/from serverfault.com only. All other websites, services ports are not accessible. I came up with these iptables rules: #drop everything iptables -P INPUT DROP iptables -P OUTPUT DROP #Now, allow connection to website serverfault.com on port 80 iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT #allow loopback iptables -I INPUT 1 -i lo -j ACCEPT It doesn't work quite well: After I drop everything, and move on to rule 3: iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT I get this error: iptables v1.4.4: host/network `serverfault.com' not found Try `iptables -h' or 'iptables --help' for more information. Do you think it is related to DNS? Should I allow it as well? Or should I just put IP addresses in the rules? Do you think what I'm trying to do could be achieved with simpler rules? How? I would appreciate any help or hints on this. Thanks a lot!

  • SQL Server 2008 - "Enhanced read-ahead and scan"?

    - by Chris J
    Hi all, Can anyone point me to, or does anyone know what this "feature" of SQL Server is? Googling for it (also for "Super scan" which seems to be a synonym for the feature) reveals no information other than all the edition comparison pages that exist out there for SQL Server. I'm also not sure whether this is a stackoverflow or a serverfault question. I'll try here on serverfault first, but if folk think stackoverflow may be a better forum, drop me a comment to that effect - ta :-)
