Default permission denied on key

Hi,
I've just noticed the following warning in the /var/log/boot file:

"
Sun Oct 23 10:35:26 2011: error: permission denied on key
'net.ipv4.conf.all.mc_forwarding'

Sun Oct 23 10:35:26 2011: error:
permission denied on key 'net.ipv4.conf.default.mc_forwarding'
"

What does it mean?

Hi! Do you have any settings in /etc/sysctl.conf ?

I don't know why this happens, but I can reproduce it manually (echo 0
> /proc/sys/net/.../mc_forwarding). I also note that the values you
set are already 0. I guess this is a kernel thing.

Cheers,

Please check current mc_forwarding state ( sysctl -a 2>&/dev/null|grep
mc_forwarding ) if it has zero value by default i think you can safely
remove "net.ipv4.conf.all.mc_forwarding=0" from your sysctl.conf. As i see
this string has to be enabled if your PC is an igmp router...

I've removed 'net.ipv4.conf.default.mc_forwarding' too.

thanks to all
