Re: Is there any way to turn off IPv6 in the stock Debian 2.6.30 kernel without recompiling?

[Rick Thomas <rbthomas55@pobox.com>]

Interestingly,

This didn't work on the Squeeze system, but it worked fine on a Lenny  
system running a stock Lenny 2.6.26-2 kernel, which seems to have been  
generated with ipv6 as a module.

Equally interestingly,

The Lenny system had no file called /proc/sys/net/ipv6/conf/*/ 
disable_ipv6

Is this new with 2.6.30 (Squeeze) kernels?  Or is it a feature of  
having ipv6 compiled in?

	Very curious!
