The 2.6.30 kernel seems to have ipv6 turned on and compiled-in --

Does this make it impossible to turn off IPv6? Or am I missing
something...
At least in sid:
head -3 /etc/modutils/aliases ; grep -i ipv6 aliases
# Aliases to tell insmod/modprobe which modules to use
# Uncomment the network protocols you don't want loaded:
# alias net-pf-10 off # IPv6
If uncomment this is not working, please report as a bug.
Hmmmm,
The system in question is running "Testing" (aka "Squeeze").
There's no such file as /etc/modutils/aliases on this system.
However, in the /etc/modprobe.d/aliases.conf file, there is (I have
abbreviated) the following set of comments:
======================
# These are the standard aliases for devices and kernel drivers.
# This file does not need to be modified.
#
# No new aliases should be added to this file, please file a bug against
# the kernel for any aliases which are still not built-in.
# network protocols
##########################################################
# 7 BRIDGE
# alias net-pf-10 ipv6
======================
The documentation for modprobe in Squeeze says that, to do the
equivalent of what Javier suggests, I should put a file called
something like "local.conf" in /etc/modprobe.d with the lines that
Mark suggested:
====================
alias net-pf-10 off
alias ipv6 off
====================
I tried that, but it didn't work -- because ipv6 is compiled-in to the
current Squeeze stock kernel. What did work, as suggested by Kelly,
was to put a file called "local.conf" in /etc/sysctl.d/ that contained
the line:
===================
net.ipv6.conf.eth0.disable_ipv6 = 1
===================
There is no such sysctl configuration option in the current stock
Lenny kernel.
Is this a bug or a feature?
If it's a bug, what package should I file it against? Is linux-
headers-2.6.30-1-amd64 appropriate? That's the current distributed
stock kernel in Squeeze...
Thanks!
Rick
