Debian 关闭 IPV6的方法

Debian 关闭 IPV6的方法

第一种:

在/etc/default/grub文件的GRUB_CMDLINE_LINUX变量中添加IPV6_DISABLE=1,然后运行update-grub,最后重启服务器。

第二种:

编辑/etc/sysctl.conf,添加或者编辑以下变量:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
最后sysctl -p即可。


附上官方原文:

How to turn off IPv6

Append IPV6_DISABLE=1 to the GRUB_CMDLINE_LINUX variable in /etc/default/grub.
Run update-grub and reboot.
or better,

edit /etc/sysctl.conf and add those parameters to kernel. Also be sure to add extra lines for other network interfaces you want to disable IPv6.

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1
After editing sysctl.conf, you should run sysctl -p to activate changes or reboot system.
