Disable IPv6

From MEPIS Documentation Wiki

Disabling Solely In Firefox

The way Firefox configures its use of the internet protocol IPv6 can slow down your connection. To disable IPv6 in Firefox:

1. In Firefox in address bar type: about:config
2. In Filter field enter: ipv6
3. change the value for network.dns.disableIPv6 to true

Disabling System Wide

Since other applications such as Opera or Thunderbird can also experience this slowdown, you may want to turn off IPv6 system-wide.

• Open a Filer Manager Session - Super User Mode

(KDE-Start> System> File System> File Manager Super User Mode)

• Navigate to directory /etc/modprobe.d
• Right click in empty space in the browser window and choose Create New > Text File ....
• Name the new file 00local (that's zero zero .... and no 3 letter .extension at end)
• Open the file by clicking on it (still in SuperUser Filemanager) and paste these two lines:

alias net-pf-10 off
alias ipv6 off

• Save and close the file
• Still in SuperUser Filemanager, click to edit the file named blacklist.
• Add this line to the very bottom of the file:

blacklist ipv6

• Save, close, and at next reboot IPv6 should be off system wide, and hopefully browsing will be a little quicker.
