this happens if ipv6 support is globally disabled, via grub config.

debian ping6 socket: Address family not supported by protocol

vim /etc/default/grub

# comment out the following line:

# GRUB_CMDLINE_LINUX="ipv6.disable=1"

# then run:


# to generate new /boot/grub/grub.cfg

on older debian / grub1

„wheezy“? „squeeze“?

checkout this config file:

vim /boot/grub/menu.lst
