![]() ![]() # replace LAN with your LAN facing interface To properly hand out IPv6s to the network clients we will need to use an advertising daemon. netctl), then it is possible to use rdnssd(8) from the ndisc6 package for that. If your chosen network management solution does not support configuring the DNS resolver with stateless IPv6 (e.g. If you are using an other firewall frontend (ufw, shorewall, etc) consult their documentation on how to enable the ipv6-icmp packets. If you are using the Simple stateful firewall/ iptables you only need to add: So for the client side the ipv6-icmp packets must be accepted. Please note that stateless autoconfiguration works on the condition that IPv6 icmp packets are allowed throughout the network. If you are using NetworkManager then it automatically enables IPv6 addresses if there are advertisements for them in the network. If you are using netctl you just need to add the following line to your Ethernet or wireless configuration. The address is automatically inferred from the prefix that your router advertises and requires neither further configuration nor specialized software such as a DHCP client. The easiest way to acquire an IPv6 address as long as your network is configured is through Stateless address autoconfiguration (SLAAC for short). Readarray l_addrs < <(/sbin/ip -6 -j address show dev "$l_if" | \ Readarray l_ifs < <(/sbin/ip -6 -j address | jq -r '. To ping everyone on all interfaces, and announce your address to everyone, use a script. ![]() The interface can be omitted in this case: If you add an option -I your-global-ipv6, link-local hosts will respond with their link-global scope addresses. With a ping to the multicast address ff02::2 only routers will respond. An interface has to be specified:Īfter that, you can get a list of all the neighbors in the local network with: ![]() Pinging the multicast address ff02::1 results in all hosts in link-local scope responding. Beginners might want to read or skim it before reading this wiki article. Yet it attempts to cover many topics that are mentioned in this article, starts from the basics, and advances in a slower pace. The tldp Linux+IPv6-HOWTO article is older, and less maintained. In Arch Linux, IPv6 is enabled by default. ![]()
