I try to disable complety ipv6 on a Linux Debian 7 (wheezy)However , things escape me. In my case, i test with grafana process (I have same issue with munin, rpcbind etc)Method 1 : with sysctlnet.ipv6.conf.default.disable_ipv6 = 1net.ipv6.conf.default.autoconf = 0net.ipv6.conf.all.autoconf = 0net.ipv6.conf.lo.disable_ipv6 = 1net.ipv6.conf.eth0.disable_ipv6 = 1Then, i reload config : sysctl -p No registration ipv6 in /etc/hostsAfter reboot process grafana, i always see, with netstat, that grafana listen ipv6 socket.tcp6       0      0 :::3000                 :::*                    LISTEN      116        23952       4022/grafana-serverReboot server : reboot the server does not improve thingsMethod 2 : disable ipv6 at kernel startupAdd GRUB_CMDLINE_LINUX=ipv6.disable=1 in /etc/default/grubGen new conf : update-grub2Reboot server : reboot the server does not improve things, i can see a listen ipv6 with netstat :tcp6       0      0 :::3000                 :::*                    LISTEN      116        23952       4022/grafana-serverI have test How it's possible to bind ipv6 socket if the stack is disable ?
