    Double-click anywhere in the line of text below on this page to select it, then copy it to the Clipboard (command-C):

    youtube.com

     

    Launch the Network Utility application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Network Utility in the icon grid.

     

    Step 1

     

    Select the Lookup tab and paste into the address field (command-V). Press return. Post the output that appears below – the text, please, not a screenshot.

     

    Step 2

     

    Select the Ping tab and do the same. Please enter the same input as you did in Step 1. Don't use the output of Step 1 as input to Step 2.

      

    Important Note

     

    Some web browsers and mail clients will automatically convert a domain name such as "www.example.com" to a clickable URL, such as http://www.example.com. That will interfere with the test. If necessary, edit the input in the Network Utility window to remove any added characters.

    Now, I only have 192.168.10.1 under my DNS servers.

     

    In the right side "search domans" I have "socal.rr.com"

    You, or someone using your computer, hacked the operating system, perhaps unknowingly. The file modified is /etc/hosts.
          
    The easiest way to fix the hosts file is to restore it from a backup that predates the modification, or to copy the unmodified file from another Mac. If you can't do that, then do as below. Please read this whole message before doing anything.

     

    Back up all data. This is a simple procedure, but if you don't follow the instructions exactly, you could be left with an unbootable system. In that case, you'll have to restore from a backup or reinstall OS X.

     

     

    If you have more than one user account, you must be logged in as an administrator.

         

     

    Triple-click anywhere in the line below to select it:

    open -e /etc/hosts

      

    Copy the selected text to the Clipboard (command-C).

      

    Launch the Terminal application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

     

     

    Paste into the Terminal window (command-V). A TextEdit window should open. At the top of the window, you should see this:

     

    ##

    # Host Database

    #

    # localhost is used to configure the loopback interface

    # when the system is booting.  Do not change this entry.

    ##

    127.0.0.1                              localhost

    255.255.255.255          broadcasthost

    ::1                                        localhost

    fe80::1%lo0                    localhost

     

    Below that, you'll see some other lines. There should be nothing above the first line "##". If you have any doubt about that, STOP and ask for guidance. Make sure you scroll all the way to the bottom of the document. Scroll bars are hidden by default until you actually start scrolling, so you may not realize that you’re not seeing the whole document.

     

    If the contents of the TextEdit window are as described, close it, then enter the following command in the Terminal window in the same way as before (by copy and paste):

     

    sudo sed -i~ '11,$d' /etc/hosts

      

    This time, you'll be prompted for your login password, which won't be displayed when you type it. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning to be careful. Confirm. Quit Terminal.

      

    If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Log in as one and start over.

      

    That will fix the hosts file. There is now a copy of the old hosts file with the name "hosts~" in the same folder as "hosts". You can delete the copy if you wish. Don't delete the file named "hosts".

    I follow the direction, and when I finish type my password then press enter, terminal actually didn't reply any message but just my user name.

    so at end where can i find the hosts file? 

  • Crunk in OSx Level 1 Level 1 (0 points)

    Thanks, work great, but I still don't understand how does it work, thank you so much anyway.

     

    sudo sed -i~ '11,$d' /etc/hosts

     

    this code means restore the hosts file right??

    now I go back to see my host list their is no more lines under the

    # Host Database

    # when the system is booting.  Do not change this entry.
