IPv6 setup with Debian and Wide DHCP Client for ipv6

To setup ipv6 in dedibox on debian , create a .sh file (script credits to rm_ ) :

nano ipv6.sh

1	nano ipv6.sh

Then copy the following in it:

#!/bin/bash
 
DUID=$1
 
skill -9 dibbler-client
dpkg -P dibbler-client
rm -rvf /etc/dibbler /var/log/dibbler /var/lib/dibbler
 
apt-get install -y wide-dhcpv6-client vim-common
 
/etc/init.d/wide-dhcpv6-client stop
 
echo 'profile default { script "/etc/wide-dhcpv6/dhcp6c-script"; };' > /etc/wide-dhcpv6/dhcp6c.conf
echo 'id-assoc pd { prefix-interface eth0 { }; };' >> /etc/wide-dhcpv6/dhcp6c.conf
echo 'interface eth0 { send ia-pd 0; };' >> /etc/wide-dhcpv6/dhcp6c.conf
echo $DUID | awk '{ gsub(":"," "); printf "0: 0a 00 %s\n", $0 }' | xxd -r > /var/lib/dhcpv6/dhcp6c_duid
 
/etc/init.d/wide-dhcpv6-client start

#!/bin/bash

DUID=$1

skill -9 dibbler-client

dpkg -P dibbler-client

rm -rvf /etc/dibbler /var/log/dibbler /var/lib/dibbler

apt-get install -y wide-dhcpv6-client vim-common

/etc/init.d/wide-dhcpv6-client stop

echo 'profile default { script "/etc/wide-dhcpv6/dhcp6c-script"; };' > /etc/wide-dhcpv6/dhcp6c.conf

echo 'id-assoc pd { prefix-interface eth0 { }; };' >> /etc/wide-dhcpv6/dhcp6c.conf

echo 'interface eth0 { send ia-pd 0; };' >> /etc/wide-dhcpv6/dhcp6c.conf

echo $DUID | awk '{ gsub(":"," "); printf "0: 0a 00 %s\n", $0 }' | xxd -r > /var/lib/dhcpv6/dhcp6c_duid

/etc/init.d/wide-dhcpv6-client start

then do:

chmod +x ipv6.sh

1	chmod +x ipv6.sh

find your duid from online.net console and run the script like and select eth0 when it asks for interface

./ip6.sh YOURDUID

1	./ip6.sh YOURDUID

To find your GATEWAY type the command below and look for a line with router advertisement , the ipv6 there is your default gateway:

tcpdump -i eth0 -n -s 4000 -v ip6

1	tcpdump -i eth0 -n -s 4000 -v ip6

now edit your /etc/network/interfaces and add:

iface eth0 inet6 static
address youripv6block::1
netmask 48
gateway yourgatewayfrom above
accept_ra 1

iface eth0 inet6 static

address youripv6block::1

netmask 48

gateway yourgatewayfrom above

accept_ra 1

If you want to add extra IP’s then just add the following below accept_ra

   up /sbin/ifconfig eth0 inet6 add 2001:your-address::2/48
   up /sbin/ifconfig eth0 inet6 add 2001:your-address::3/48

1 2	up /sbin/ifconfig eth0 inet6 add 2001:your-address::2/48 up /sbin/ifconfig eth0 inet6 add 2001:your-address::3/48

In your sysctl.conf Add/change the following to like these:

net.ipv6.conf.all.autoconf = 0
net.ipv6.conf.default.autoconf = 0
net.ipv6.conf.eth0.autoconf = 0
net.ipv6.conf.eth0.accept_ra=1

net.ipv6.conf.all.autoconf = 0

net.ipv6.conf.default.autoconf = 0

net.ipv6.conf.eth0.autoconf = 0

net.ipv6.conf.eth0.accept_ra=1

To apply settings:

sysctl -p

sysctl -p

Now type:

nano /etc/rc.local

1	nano /etc/rc.local

and paste this before exit 0:

/etc/init.d/wide-dhcpv6-client restart
ifdown eth0 && ifup eth0

1 2	/etc/init.d/wide-dhcpv6-client restart ifdown eth0 && ifup eth0

Now type:

ifdown eth0 && ifup eth0

1	ifdown eth0 && ifup eth0

Also you need to have port 546 and port 547 opened in your profile for udp

now:

ping6 ipv6.google.com:

PING ipv6.google.com(la-in-x64.1e100.net) 56 data bytes
64 bytes from la-in-x64.1e100.net: icmp_seq=1 ttl=53 time=38.7 ms
