Nope - a reboot didn't work either. Followed those instructions to the letter - and IPV6 is still loading up.
<br />
<br />And trying "rmmod ipv6" returns "ERROR: Module ipv6 is in use by cnic", even though I've told it in all those places not to start IPV6.
<br />
<br />Oh well. I'll just set ip6tables to block everything, and worry about shutting down IPV6 later.

Thanks for the idea
Christoph.
<br />>
<br />> I had tried some of that last night, but not all.
Unfortunately, it didn't shutdown IPV6 right away. A reboot might work, but
I've got to wait till tonight to try
that.
<br />>
<br />> And every time I tried to restart SSHD with the
"ListenAddress 0.0.0.0" uncommented - it would error with "You've
got to specify ports before a ListenAddress". The weird part - I already
had a "Port" command in there. I tried adding a second port (I run
some of my SSH server on two different ports - so I can get in from the outside
while the main router blocks everything on port 22). But that didn't work
either. Weird - even with the Port command in there, I'd get the same
error.
<br />>
<br />> Thanks for the
try.

As workaround you might want to use a blackhole route for
IPv6.
