IPv6 Kurulumu

IPv6, bir çok durumda direk çalışabilir ama bazı durumlarda veya bazı internet sağlayıcılarında, IPv6'i etkinleştirmen için baz ayarları değiştirmen gerekebilir.

OVH üzerinden VPS ile

OVH gives one IPv4 address and one IPv6 address for VPS but by default, only IPv4 is OK. Please check The OVH documentation.

Configure the DNS server

Also check the documentation for subdomains.

Configure the server

On the OVH panel, you will copy 3 elements:

• the IPv6 address
• the IPv6 gateway address
• the IPv6 prefix. On OVH's VPS SSD, prefixes are /128 because you have only one IPv6 address.

On your VPS, create a backup of the network configuration with : cp /etc/network/interfaces ~/interfaces in home directory. Then, you can edit the configuration file (/etc/network/interfaces) with the following.

not

In this example, it is assumed that your network interface is eth0. If it's different (check with ip a) you need to adapt the example below.

iface eth0 inet6 static
address <your IPv6 address>
netmask <your IPv6 prefix>
post-up /sbin/ip -6 route add <the IPv6 gateway> dev eth0
post-up /sbin/ip -6 route add default via <the IPv6 gateway> dev eth0
pre-down /sbin/ip -6 route del default via <the IPv6 gateway> dev eth0
pre-down /sbin/ip -6 route del <the IPv6 gateway> dev eth0

Now, save the file and restart the network service with : service networking restart. (TODO : ideally we should find a way to validate the content of the configuration, otherwise it could fuck up the network stack and get disconnected from the VPS ?)

Check your configuration with these commands :

• ip a to display network interfaces and addresses
• hostname -I to display the system IP addresses
• try to ping an IPv6 server (for example you can use ping6 ip6.yunohost.org)
• try to ping your server from your PC (assuming your PC has IPv6 enabled)

If it's ok, it's ok !
