• Disabling IPv6 in Debian

  Date: 2010.04.22 | Responses: 0

  I’ve seen different suggestions, so I decided to include all of them.

  Edit: /etc/modprobe.d/aliases

  By default you will have a line like this:

  alias net-pf-10 ipv6

  Replace that line with:

  alias net-pf-10 off

  alias ipv6 off

  Also, while we’re at it, on your desktop machines, help out Firefox by disabling IPv6 there too. It’s simple, in the location bar enter:

  about:config

  Then search for:

  network.dns.disableIPv6

  I also disabled these lines in /etc/hosts to avoid confusions:

  ## The following lines are desirable for IPv6 capable hosts

  #::1 localhost ip6-localhost ip6-loopback

  #fe00::0 ip6-localnet

  #ff00::0 ip6-mcastprefix

  #ff02::1 ip6-allnodes

  #ff02::2 ip6-allrouters

  #ff02::3 ip6-allhosts

  Finally, “open file /etc/sysctl.d/bindv6only.conf and set net.ipv6.bindv6only=0, then restart the procfs with invoke-rc.d procps restart”

• Controlling the speed of your localhost network

  Use iprelay, for example, say you want to only allow 10K/s on your localhost network, then you’d type

  iprelay -b10000 8000:localhost:80
