\nThe \u201ctrick\u201d here, as described by TrevorH1 in #linux, is that programs can still load the module as they wish. You can check this by running lsmod or modprobe -l, you will still see the ipv6.ko kernel module. This allows user mode programs to access the kernel module in their code (so they don\u2019t crash); but as far as the kernel is concerned ipv6.disable=1, so the kernel doesn\u2019t really allow much to get through it.<\/p>\n
And that\u2019s it. IPv6 is disabled on your box\u2026 but if you want to disable a variety of fun things that you might find when seeking to disable IPv6\u2026<\/p>\n
