禁用IPv6
$ su -
# nano /etc/sysctl.conf
并将这些行添加到sysctl.conf文件中
#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
使用新的配置保存sysctl.conf文件,并运行以下命令以启用新设置:
# sysctl -p
再次检查系统
$ cat /proc/sys/net/ipv6/conf/all/disable_ipv6
现在您应该看到“ 1”表示您的系统已禁用IPv6。

在Ubuntu 11.04中关闭IPv6
首先,打开或关闭,检查一下
$ ifconfig -a

其次,关闭,我按如下方式修改了该行并修补了grub
$ grep ipv6 /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 quiet splash"
$ update-grub
