IPv6 and IP routing SuperMini-Howto
Extremely simple guide to using IPv6 and the command IP on Linux
- Hosts and aliases should be placed in /etc/hosts
- Adding IP aliases for more IPs to a interface
- xinetd and ipv6
:)
1. Hosts and aliases should be placed in /etc/hosts
This file should atleast include
# IPV6 versions of localhost ::1 localhost ipv6-localhost ipv6-loopback fe00::0 ipv6-localnet ff00::0 ipv6-mcastprefix ff02::1 ipv6-allnodes ff02::2 ipv6-allrouters ff02::3 ipv6-allhostsf
And perhaps some local hostnames..

2. Adding IP aliases for more IPs to a interface
2.1. Using "ip"
/sbin/ip -6 addr add <ipv6address>/<prefixlength> dev <interface>
Example:
/sbin/ip -6 addr add 3ffe:ffff:0:f101::1/64 dev eth0
2.2. Using "ifconfig"
/sbin/ifconfig <interface> inet6 add <ipv6address>/<prefixlength>
Examples:
ifconfig eth1 inet6 add 2001:0618:0400:965a:0000:0000:beef:babe/64 ifconfig eth1 inet6 add 2001:0618:0400:965a:0000:0000:dead:0101/64
3. xinetd and ipv6
xinetd has support for IPv6. Add
flags = IPv6
to the configuration file for all services you want. Example:
service ircd
{
flags = IPv6
socket_type = stream
protocol = tcp
wait = no
user = nobody
server = /usr/sbin/bitlbee
port = 6667
disable = no
}
