My Karmic Koala upgrade Ubuntu 9.10

By Steph on 07/10/2009 under Ubuntu

Like many, I had the great Karmic Koala to Ubuntu 9.10. and this is the first little problem: DNS resolution long. Fortunately everything is back to normal with these two manipulations:

This post is complete with the following:-hotfixes ubuntu-karmic-koala-9-10

Disabling IPv6

karmic-koala
IPv6 is the future protocol should replace the current IPv4. But its adoption is slow and there is a good chance that you will not be useless. Since version 2.6.28 of the Linux kernel, it is possible to black-list the kernel module dedicated to this function. The trick is to disable ipv6 then add an option in / etc / default / grub, line GRUB_CMDLINE_LINUX = "" add ipv6.disable = 1 between the double quote:
giving GRUB_CMDLINE_LINUX = ipv6.disable=1 "

  sudo update-grub 

To monitor IPv6 is disabled:

  inet6 ip a | grep inet6 

This command does not return the form

  128 scope host inet6:: 1 / 128 scope host
 64 scope link inet6 fe80:: 219: 21FF: fe34: 1BAE / 64 scope link 

DNS on Livebox

The resolution of names is very long since this upgrade, and when looking around I realized that

  etc / dhcp3 / dhclient.conf sudo vi / etc / dhcp3 / dhclient.conf 

and add the following line:

  supersede domain-name-servers 80.10.246.130, 81.253.149.10; 

I will continue to supplement this article with other concerns that I meet

    attention, there is a critical bug in Ubuntu 9.10 that prevents access to the Internet via DSL. https: / / bugs.edge.launchpad.net/bugs/432205
    If you have a DSL connection, wait one version 9.10.1 fixes the bug before installing Karmic!

    Unfortunately the problem persists with a livebox sagem. The livebox filter some frames DNS. Why? Impossible to know.

    After inspection of the offending frames with wireshark, nothing to report. They conform to the protocols (from what I could see). In 9.04, everything worked like a charm. I am a bit lost and I do not see anyone respond. Maybe I'm the only one to have an old Sagem?

    Bah I've got a mini livebox thomson and I also have the problem on a eeepc 701.
    At the command ip .... I return it should not.: (
    But I did not file: / boot / menu.lst. (or empty).
    If someone has an idea ... (siouplé) :)

    hi,

    I corrected the article to disable ipv6

    in / etc / default / grub line GRUB_CMDLINE_LINUX = "" add ipv6.disable = 1 between the double quote

    giving GRUB_CMDLINE_LINUX = "ipv6.disable = 1"

    sorry for the late update!!

    Already done my part but still ping crazy (between (500 and 700 ms on google.fr).
    By cons file. Conf gives me an error and therefore can not edit: error in swap file I understand.

  • Steph

    The swap has nothing to do with the bp network. Can you post the error message ... ..

  • yannoslemanos

    So much for the pc that works;
    E325: ATTENTION
    Found a swap file by the name "/ etc/dhcp3/.dhclient.conf.swp"
    owned by: root dated: Fri Nov 13 21:15:36 2009
    file name: / etc/dhcp3/dhclient.conf
    modified: YES
    user name: root host name: yanneeepc
    Process ID: 2247
    While opening file "/ etc/dhcp3/dhclient.conf"
    dated: Tue Oct 9 00:51:03 2009

    (1) Another program may be editing the same file.
    If this is the case, be careful not to end up with two
    different instances of the same file when making changes.
    Quit, or continue with caution.

    (2) An edit session for this file crashed.
    If this is the case, use ": recover" or "vim-r / etc/dhcp3/dhclient.conf"
    to recover the changes (see ": help recovery").
    If you did this already, delete the swap file "/ etc/dhcp3/.dhclient.conf.swp
    "
    To avoid this message.
    "/ Etc/dhcp3/dhclient.conf" 53 lines, 1716 characters
    Press ENTER or type command to continue

    but I do not understand about the other 701. The last line is #)
    If I write the new line, it does not write what I type.
    Thank you for ance I have no response on ubuntu-fr.org : (

  • dede

    I thank you + + + +
    it works great, I forget
    -> Sudo update-grub
    it's ok.

  • Dodu

    Hi, I use a live usb karmic, and I can not change the file because it is read only, how?
    Thank you.

  • Steph

    do you really sudo ?????
    if not do before:

      / etc / dhcp3 / dhclient.conf sudo chmod 777 / etc / dhcp3 / dhclient.conf 
  • Dodu

    Well, I could edit the file
    in GRUB_CMDLINE_LINUX = "ipv6.disable = 1"
    but when I do
    sudo update-grub
    I:
    error: can not open `/ dev / sdf 'while attempting to get disk size
    grub-probe: error: can not find a device for /.
    In addition, when I
    ip a | grep inet6
    I live
    inet6:: 1 / 128 scope host
    inet6 fe80:: 219:21 ff: fe34: 1bae/64 scope link
    mean that IPv6 is still enabled, right?
    thank you
