Wider question:
Say I'm running a system with both IPv4 and IPv6 enabled.
Stuff Happens(tm) and I want to completely disable IPv6 for some
indefinite but temporary period - not chamge any configuration
settings or firewall rules, but just have the code finish processing
current packets (or not) and then ignore further traffic. There will
be consequences; I'm prepared to accept them.
Is there a single master switch - a sysctl, perhaps, or something
in /etc/rc.d - that lets me do that?
Respectfully,
Robert Huff
