On my system I see the following values: $cat /sys/module/ipv6/parameters/disable_ipv6 0
$ sudo sysctl net.ipv6.conf.all.disable_ipv6 net.ipv6.conf.all.disable_ipv6 = 1 $ sudo sysctl net.ipv6.conf.default.disable_ipv6 net.ipv6.conf.default.disable_ipv6 = 1 Are you suggesting that "cat /sys/module/ipv6/parameters/disable_ipv6" should be 1?
