What is Ping?

Ping is a term that’s thrown around all over the place. That being said, the root of what a ping actually is remains the same throughout most of them. In basic terms, it is a utility used to test the reliability of a connection between two points on the Web. Ping is often used during gaming, Internet, and local network troubleshooting, and various other connection tests to determine the root of a problem. There are several applications in which we use ping today. Here are some of them.

Internet Connectivity

Windows, OS X, and Linux users all have access to a very easy and simple method of testing an Internet connection. By opening Terminal (Command Line or “CMD” on Windows), you can simply type ping www.google.com to test your ability to reach Google. This can be a helpful way of determining whether or not a problem pulling up Google (or any other page) is caused by a general lack of ability to connect to the Web, or something more localized to the browser you’re using. If you receive all of your packets back, but the delay time is considerably high (1,000 or more milliseconds), you may be experiencing problems between your local network and the site’s server. The best way to test this is by sending a ping to another site that you know isn’t hosted by the same company.

Network Troubleshooting

You can also ping an IP address to test your connection with a specific computer or device. By sending a ping request to, you are able to test whether or not your computer’s networking hardware and software is functioning properly. This is typically one of the first steps taken during Internet and local network connection troubleshooting. If you don’t receive any packets, or only some of the packets, sent using the ping command to that address, you may have something wrong with your networking hardware, drivers, or some other software configuration. If you receive the ping back from your networking equipment’s loopback, you can also send ping commands to the other computers in your network directly to their IP address, which will usually start with 192.168.


If you play online games, you’ve probably noticed a ping reading on you and the folks you are playing with. This reading lets you know how long it takes each person’s commands to be sent to the server and received back at home. In short, the larger your ping, the more lag you’ll notice during gameplay. Some servers (especially on FPS games) will enact a policy that automatically kicks you out if your ping exceeds acceptable limits. Ideally, you want your ping to be less than 100 milliseconds.

By using this simple tool, you can better understand and resolve a large variety of different connectivity issues that may occur. You can even avoid potentially unpleasant experience in otherwise fun games.

    @twitter-46976601:disqus I can confirm you do NOT need a UDID.

  • Dan

    It downloaded as dmg what do I do now

    • Jim Gresham

      Double click the dmb and it will extract the .ipsw file.  Then follow the rest of the steps.  Make sure you are using iTunes beta 9.

      • Guest

        how do i do this on windows 7? i tried winimage to extract the file and got an error reading file

      • Puter

        If we’re supposed to use beta 9, why does the article link to beta 7?

        Do we have a link to beta 9?

  • Anonymous

    It works.  IOS 5 on my iphone 4 now.  No need to register the UDID.  Download winimage to extract the ipsw file from the dmg file and restore.

  • Jorge W Machado

    Have any one of you tested with gevey sim card ? THX

    • Jesús Robles

      Yes, and they do NOT work. They haven’t since iOS 5 beta 2.

      • Anonymous

        That’s not true, they were working on beta 7. I’m not sure if it was the regular Gevey or the Turbo or the Ultra, but on beta 7 at least one type of Gevey WAS working.

        Whether or not it works on this release of iOS5 though is not something I’m aware of yet.

    this does not work for my 3Gs

    • Billy

      Did not work on my 3GS either =(

  • Oldrelicdvds

    Seems the CDMA version is not for Verizon Wireless. No IPSW file after extraction. Four files, but no IPSW.

    • Thindjinn

      Did you extract 2 after the first extrctions?

  • Rick

    C’mon Pirillo, are you insane? This GM is meant to developers. This is confidential information. You are violating the NDA and doing piracy.

    Apple will fall on your head soon.

    • Noah

      It sucks, because this will be the first time anyone will have ever violated NDA and pirated anything, especially iPhone iOS GMs.

  • guest

    worked perfectly on my ipod touch 4g

  • torneedsyou

    Anyone tried it for the ipad?

  • bluedevil229

    I’m getting error 21 too.  OSX Lion.  I’ve rebooted, re-downloaded the dmg, everything.

    • LimeyNR

      Make sure you guys are installing the latest Beta of the new iTunes before doing the rest. It won’t work with older versions.

  • bluedevil229

    Oh, and I’m trying it for the iPad 2.  Error 21.

  • Michael Sheffield

    This worked for me on both my iPhone 4 and my iPad 1, just followed the instructions. :-)

  • Michael Sheffield

    yes, I think so, I tried without updating my iTunes and it didn’t work but did after.

    • Scott Kauer

      Did you keep getting the Error 21 before updating? That’s the one that I got. I am d’ling the iTunes 10.5 beta 9 now and will see….

      • http://twitter.com/DRainsbergerii David Rainsberger II

        did it work?

      • Michael Sheffield

        yea worked great, I didn’t get any errors once I updated iTunes.

      • http://twitter.com/Trevor84 Trevor Hartley

        I’ve seen that error a few times in the past.  If you’ve used TinyUmbrella, you should make sure that you’ve unchecked that setting for “Set Hosts to Cydia on Exit” under the Advanced tab.

  • Dale O’Donnell

    I’ve been using iOS 5 since the beta’s were released, but I’m still excited about the official release. Having a few problems but I’m sure they will be sorted in time!

  • Cmiller82

    Does not work for me. Every time I try to load ios5 i get a error and have to restore back to ios4. am i missing a key step that is not in the walk through?

    The iPad files you’ve linked to above, are the WiFi + 3G ones for iPad 1 or 2? If they’re 2, where can the iPad 1 3G GSM files be downloaded from?

  • Alex McCabe

    Discovered a pretty major bug. I have a passcode on. When you double tap the home button when the phone is locked, go to camera, then gallery, then press the home button. You are in the phone. Passcode averted.

    • Cyrus

      Actually, the phone goes back to the lockscreen.

    • bonafidejed

      I had the same result as Cyrus. Are you sure your phone had gone into locked mode … check the Auto-Lock durations.

      Try and recreate again:
      a) Ensure the phone is passcode locked:
           i) slide to unlock
           ii) when you get to the passcode screen, hit cancel to go back. (If you aren’t prompted to enter your lock code, wait for longer than your Auto-Lock duration, then start back at (a).)
      b) double-tap the home button.
      c) go into the gallery. At this point you should not be able to see any photos (other than the ones you’ve taken in this session) because the phone is locked.
      d) tap the home button. It should take you back to the passcode screen.

    • Jennifer

      I just tested it out on mine with a passcode and it and it only shows a gallery of the pics I took while my phone was locked.  You are not “in the phone”.  In fact, when I tried to get into the gallery before I took a pic, it asked for my passcode.

  • gawd

    Any way to reverse this upgrade? My phone can’t connect to itunes at all anymore… I got ios5 up and running but I just get errors from itunes… and my messages + pictures got lost ???

    I have an iphone 4 GSM, most up to date itunes version, tried to upload iOS5 and gave me an error and had to restore to 4.3.5….any ideas?

    • Jennifer

      what was the error number? also, when you say, “most up to date iTunes version” do you mean 10.4 or 10.5?  You need 10.5 beta.

    This isn’t working for me either. have latest beta of each as provided in this article, and my iTunes is giving an error, saying i am not eligible for this build (during initial verifications stage). Tried using tiny umbrella to redirect hosts, but just gives me error 11.
     Well, guess i’ll have to wait. 

    • http://twitter.com/SnitchPurple187 Sergio Espina

      I got it working! you have to convert the .dmg file to an IPSW with a program such as PowerISO

    If you are using Windows 7 64bits, installing iTunes 10.5 beta 7 for Win7x64 will kill your iTunes. 
    DONT DO IT!!

      What do you mean “kill” your iTunes? What error messages are you getting? It worked just fine for me.

    iTunes just stop working, it didnt start up at all and thats it.

    I had to restore Windows to a previous checkpoint and then repair iTunes with the actual version setup file. I have Win 7 Ultimate 64x. I didnt uninstall iTunes prior the beta7 installation so maybe that was the problem, I just installed it on top of the actual version… but this is a known issue at the Apple forums.

    I think I’ll just wait for the offical release :-)

    Sorry for the bad english.

  • Jennifer

    Use the “restore” button instead of the “update” button. Go back and re-read the instructions to see if there’s anything else you missed too.
