Disable ipv6 on Ubuntu

There is a strange problem with kernel message: lo: Disabled Privacy Extensions
It is caused by the ipv6 module in kernel.
reference:
Old Nabble - ubuntu-users - lo: Disabled Privacy Extensions

To close it, you have to recompile kernel.
There is a hack to close it through the loader. (If no ipv6 needed)
edit the /etc/default/grub and modify:
GRUB_CMDLINE_LINUX="ipv6.disable=1"

here are the references to close it:

有時讓使用者上傳圖片，會怕惡意的上傳可執行的php，雖然可以用改檔名來防止，就怕駭客使用非正規的方法上傳檔案，因此在上傳的目錄下，要設定不執行php的安全性設定。

httpd.conf 在網站的上傳目錄設定下：
<Directory "/home/axer/php/zdemo/upload">
AllowOverride None
php_flag engine off
Allow from all
</Directory>
