Enabling/Disabling IPv6
In flight
- Note
- Enabling or disabling IPv6 this way is only in effect until next boot.
Disabling
sysctl -w net.ipv6.conf.all.disable_ipv6=1
sysctl -w net.ipv6.conf.default.disable_ipv6=1
sysctl -w net.ipv6.conf.lo.disable_ipv6=1
Enabling
sysctl -w net.ipv6.conf.all.disable_ipv6=0
sysctl -w net.ipv6.conf.default.disable_ipv6=0
sysctl -w net.ipv6.conf.lo.disable_ipv6=0
Manually adding an IPv6 Address
ifconfig eth0 add 2001:16d8:dd85:139::50/64
Static configuration
Example of configuration of IPv6 on eth1 in /etc/network/interfaces
iface eth1 inet6 static
pre-up modprobe ipv6
address 2001:0470:51dc:1::1
netmask 64
Disable permanent
Add the following lines to /etc/sysctl.conf.
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
Configure as IPv6 Router
Uncomment the line net.ipv6.conf.all.forwarding=1 in /etc/sysctl.conf and reboot
Install Route Advertisement daemon for IPv6
sudo apt-get install radvd
Configure radvd
Example configuration of /etc/radvd.conf shown below. (See /usr/share/doc/radvd/examples)
interface eth1
{
AdvSendAdvert on;
prefix 2001:470:51dc:1::/64
{
AdvOnLink on;
AdvAutonomous on;
};
};
DHCP Other-Config flag
interface eth1
{
AdvSendAdvert on;
<notice>AdvOtherConfigFlag on;</notice>
prefix 2001:470:51dc:1::/64
{
AdvOnLink on;
#//MaxRtrAdvInterval 10;
AdvAutonomous on;
};
};
