howto disable ipv6

Asked by Canale Grande

I just installed feisty fawn (7.04) and noticed a dramatic speed problem with newsreading and cxoffice ftp services.
I would like to know how to disable ipv6 because I really don't need it.

Hi,

sudo gedit /etc/modprobe.d/aliases
And change the line:
alias net-pf-10 ipv6
to:
alias net-pf-10 off ipv6
This will disable IPv6 on all network interfaces. You need to reboot

If it's not already set, disable IPv6. In the url enter about:config and find the ipv6 entry and disable it.

Edit the file /etc/modprobe.d/aliases with root-privileges and change the line saying:

alias net-pf-10 ipv6

(line 17 for me)
to:

alias net-pf-10 off

IPv6 should be disabled after the next reboot or when typing

sudo modprobe -r ipv6

Can you help with this problem?
