Hi, for official IPv6 i'm useing sixxs as tunnelbroker, these steps i've done connect a Debian OpenVZ system to a IPv6 Network for the VE with a venet0 interface:
1) Setup an IPv6 Tunnel (-> https://noc.sixxs.net/ ) Relevant IPv6 settings in "/etc/network/interfaces" [...] # device: sixxs ipv6 tunnel with static IPv6 auto sixxs iface sixxs inet6 v4tunnel address <your_assigned_IPv6_ADDRESS> netmask 64 endpoint <IPv4_ADDRESS_of_tunnelbroker> ttl 64 up ip link set mtu 1280 dev sixxs up ip route add default via <IPv6_ADDRESS_of_tunnelbroker> dev sixxs [...] VE_0$ ifup sixxs 2) Setup OpenVZ with IPv6 : # enable IPv6 forwarding for all Interfaces VE_0$ sysctl -q -w net.ipv6.conf.all.forwarding=1 # enable IPv6 in /etc/vz/vz.conf -> IPV6="yes" # and restart OpenVZ Subsystem, so venet has a IPv6 Address VE_0$ /etc/init.d/vz restart # give a VE an IPv6 address, you need a IPv6 subnet ( https://noc.sixxs.net/ ) VE_0$ vzctl set <VEID> --ipadd <IPv6_ADDRESS> [--yes] 3) Test it If you connected to an official IPv6 network, you can test it, by pinging debian.systs.org ( 2001:6f8:109a::1a01 ) or visit IPv6 sites like http://www.kame.net and see the dancing turtle ;-) Bye, Thorsten -- Thorsten Schifferdecker [EMAIL PROTECTED] ---//--- Am Do, 24.01.2008, 18:29, schrieb Benoit Branciard: > Temporarily giving up messing with veth devices (forgot dhcpd server for > now), I concentrated on setting up a basic VS with both IPv4 and IPv6 > addresses, using standard venet device. > > I'm using Debian Etch hardware node with debian.systs.org packages. > > So I did: > > - install packages and reboot as necessary : > fzakernel-2.6.18-686 vzctl vzctl-ostmpl-debian vzdump vzprocps vzquota > > - ensure /etc/sysctl.conf contains : > > net.ipv4.conf.default.forwarding = 1 > net.ipv4.conf.all.rp_filter = 1 > kernel.sysrq = 1 > net.ipv4.conf.default.send_redirects = 1 > net.ipv4.conf.all.send_redirects = 0 > > - ensure /etc/vz/vz.conf contains: > IPV6="yes" > > - create VS : > vzctl create 112 --ipadd XXX.YYY.ZZZ.12 --ipadd xxx:yyy:zzzz::12 > --hostname brahma-vps112 > > (default template is debian-4.0-i386-minimal, hardware node has only one > physical interface activated, on the same subnet as VS) > > - start VS : > vzctl start 112 > > > Result: > > - IPv4 VS works as expected (ping succeeds from hardware node, external > server in same subnet, external server on another subnet). > > - IPv6 VS doesn't work !!!
