好像真是个BUG，通过升级内核可以解决，网上查到了几篇文章，英文的
Howto Disable IPV6 at Ubuntu Jaunty
EDIT : Updated for latest Ubuntu Jaunty.There is a kernel bug at ubuntu jaunty's current kernel, you can read the comments to get more details(bug page, patch etc) about this issue.SO this is the only way to disable ipv6 without compiling new or your current kernel!
You have to install a 2.6.29.3 or a later kernel.You can find debian packages of kernels from here
In this example we are going to install 2.6.29.3 kernel.If you have problems with this kernel, you can always install a newer kernel.Also i will use i386 packages, if you have a 64bit system, install and use 64 bit packages from there!
Now navigate to kernel ppa by clicking here and install the debian files :
linux-headers-2.6.29-02062903-generic_2.6.29-02062903_i386.deb
linux-headers-2.6.29-02062903_2.6.29-02062903_all.deb
linux-image-2.6.29-02062903-generic_2.6.29-02062903_i386.deb
For i386 packages example :
$wget -c http://kernel.ubuntu.com/~kernel-ppa/ma ... 3_i386.deb
$wget -c http://kernel.ubuntu.com/~kernel-ppa/ma ... 03_all.deb
$wget -c http://kernel.ubuntu.com/~kernel-ppa/ma ... 3_i386.deb
Now install it :
$sudo dpkg -i *.deb
###################
Optional part :
Now open start up manager (You can install it via $sudo apt-get install startupmanager) via System > Administration > StartUp-Manager navigation or startupmanager command.
Change default operation system to latest kernel we installed (Ubuntu 9.04, kernel 2.6.29-02062903-generic) and close it.
###Optional part ends
Open your grub menu config via :
$sudo gedit /boot/grub/menu.lst
command.Find the kernel line which we installed a couple of minutes ago, and add option ipv6.disable=1
It will look like this :
title Ubuntu 9.04, kernel 2.6.29-02062903-generic
uuid 96c2b3cb-f93c-4601-ac54-922c9efd8de0
kernel /boot/vmlinuz-2.6.29-02062903-generic root=UUID=96c2b3cb-f93c-4601-ac54-922c9efd8de0 ro quiet splash ipv6.disable=1
initrd /boot/initrd.img-2.6.29-02062903-generic
quiet
Edit : I am also posting a screen shot of this , since my theme's width is a little small : ) You can find the screenshot here.
Update your grub via :
$sudo update-grub
Reboot your box with 2.6.29-03 kernel.To be sure, open a terminal and paste this command (change eth0 to your network interface : eth1,eth0, wlan0 etc)
$ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:1d:92:4b:92:c7
inet addr:94.54.36.125 Bcast:94.54.63.255 Mask:255.255.192.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:228348 errors:0 dropped:0 overruns:0 frame:0
TX packets:2891 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:16159134 (16.1 MB) TX bytes:486253 (486.2 KB)
Interrupt:27 Base address:0xe000
If the output is similar to this (no extra lines like 213123/64), then you have disabled ipv6
