Squeeze and the Java plugin (SOLVED)

Another Squeeze issue popped up: the Sun Java plugin (i.e., sun-java6-plugin) doesn't work. It took a bit of poking around to find a fix, but here it is. As root in a terminal:

# nano /etc/sysctl.d/bindv6only.conf

Then change

net.ipv6.bindv6only = 1

to

net.ipv6.bindv6only = 0

Finally,

# invoke-rc.d procps restart

I have no idea what other positive or negative ramifications this will have to your system, so proceed with caution. I'm pretty sure you can undo any damage by setting the 0 back to 1 and doing the invoke-rc.d call over.

FWIW, the icedtea6-plugin doesn't work either, but I haven't been able to figure out that one.
