    Thumbs up Slow dns fix!

    If you are experiencing slow DNS in Fedora, here is a great workaround instead of disabling IPV6. Just add options single-request to /etc/resolv.conf if you are running 'network'
    Edit this file
    Code:
    vi /etc/resolv.conf
    Add options single-request to bottom of file and save
    Code:
    nameserver 4.2.2.1
    nameserver 4.2.2.3
    options rotate
    options single-request
    If you are running 'NetworkManager' and know how to add options to /etc/resolv.conf when it gets built post the steps below and I will add them here.

    Re: Slow dns fix!

    Thanks for the post!

    To add this to my /etc/resolv.conf file when using NetworkManager, I created a script in /etc/NetworkManager/dispatcher.d called 06-dhclientoptions


    Code:
    #!/bin/bash
    #
    # This is for adding any custom dhclient options to the end of /etc/resolve.conf file
    #
    # 2010.09.15 - Created
    #
    echo "options single-request" >> /etc/resolv.conf

    Also, remember to chmod +x /etc/NetworkManager/dispatcher.d/06-dhclientoptions
