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

Sadly, it was a good idea but it didn't work.
Apparently, having the module compiled in prevents any of the
modprobe stuff from having any effect on it.
However, Kelly gave me a pointer that led me to the right fix.
Yeah, I noticed.
I don't think this is a debian stock kernel tho..
lsmod |grep ipv[4-6]
(incase the ipv5 virus is spreading :P)
Jokes aside.. I got a feeling this is a hand made kernel, the ipv6
bit has (to what I could find in the change logs) not been jammed in
the kernel itself.
X11 is annoyed with ya for having ipv6 support, but dropping the
traffic at the kernel.. it does not understand what happend. X11 has
"native"ipv6 support (so it seems).
Give us a uname -a for the fun of it.

If X11 is upset by turning off ipv6 at the kernel, why does it work
with "eth0" but not with "all" ??!!
And why is there no "DISPLAY" variable in the shell environment?
It's not a self-made kernel. I got it from the "testing" repo just a
couple of weeks ago.
lsmod | grep ipv
gives nothing.
Note that we have "CONFIG_IPV6=y" not "=m" in the config file...
Curiouser and curiouser!
