ipv6 on Debian with Nginx

[Matt]

Matt submitted a new resource:

ipv6 on Debian with Nginx - Enable and set up IPv6 on Debian with Nginx

First, make sure nginx is built with IPv6 support

root@debian:~# nginx -V | grep -w ipv6
nginx version: nginx/1.7.1
built by gcc 4.7.2 (Debian 4.7.2-5)
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp...

How do you get the ip's to stick after a reboot. While this works as soon as the server is rebooted they are gone again.

How do you get the ip's to stick after a reboot. While this works as soon as the server is rebooted they are gone again.

What do you have in your /etc/network/interfaces file?

 

[Matt]

I've not actually rebooted mine since setting it up.

root@debian:/home/scripts# uptime
06:52:07 up 205 days, 12:33,  1 user,  load average: 0.04, 0.08, 0.19

[Matt]

I've specifically added the IP addresses that I want to be available in the inet6 stanza

iface eth0 inet6 static
        address 2001:41D0:8:C463::1
        netmask 128
        post-up /sbin/ip -f inet6 route add 2001:41D0:8:C4ff:ff:ff:ff:ff dev eth0
        post-up /sbin/ip -f inet6 route add default via 2001:41D0:8:C4ff:ff:ff:ff:ff
        up ip addr add 2001:41d0:8:c463::2 dev eth0
        up ip addr add 2001:41d0:8:c463::3 dev eth0
        pre-down /sbin/ip -f inet6 route del default via 2001:41D0:8:C4ff:ff:ff:ff:ff
        pre-down /sbin/ip -f inet6 route del 2001:41D0:8:C4ff:ff:ff:ff:ff dev eth0
        down ip addr del 2001:41d0:8:c463::2 dev eth0
        down ip addr del 2001:41d0:8:c463::3 dev eth0

 

[Akia]

well I've tried it everywich way but can't get it to work.

I've tried how you've got it

like this

iface eth0 inet6 static
    address 2001:41D0:2:3B9c::
    netmask 64
    post-up /sbin/ip -family inet6 route add 2001:41D0:2:3Bff:ff:ff:ff:ff dev eth0
    post-up /sbin/ip -family inet6 route add default via 2001:41D0:2:3Bff:ff:ff:ff:ff
up ip -6 addr add 2001:41d0:2:3b9c::1/64 dev eth0
up ip -6 addr add 2001:41d0:2:3b9c::2/64 dev eth0
up ip -6 addr add 2001:41d0:2:3b9c::3/64 dev eth0
up ip -6 addr add 2001:41d0:2:3b9c::4/64 dev eth0
up ip -6 addr add 2001:41d0:2:3b9c::5/64 dev eth0
    pre-down /sbin/ip -family inet6 route del default via 2001:41D0:2:3Bff:ff:ff:ff:ff
    pre-down /sbin/ip -family inet6 route del 2001:41D0:2:3Bff:ff:ff:ff:ff dev eth0
down ip -6 addr del 2001:41d0:2:3b9c::1/64 dev eth0
down ip -6 addr del 2001:41d0:2:3b9c::2/64 dev eth0
down ip -6 addr del 2001:41d0:2:3b9c::3/64 dev eth0
down ip -6 addr del 2001:41d0:2:3b9c::4/64 dev eth0
down ip -6 addr del 2001:41d0:2:3b9c::5/64 dev eth0

but that still dosn't work

 

[Matt]

Hmm, I probably shouldn't reboot my debian server then

 

[Akia]

Hmm, I probably shouldn't reboot my debian server then

this seems to work:

iface eth0 inet6 static
    address 2001:41D0:2:3B9c::
    netmask 64
post-up ifconfig eth0 inet6 add 2001:41D0:2:3B9c::1/64
post-up ifconfig eth0 inet6 add 2001:41D0:2:3B9c::2/64
post-up ifconfig eth0 inet6 add 2001:41D0:2:3B9c::3/64
post-up ifconfig eth0 inet6 add 2001:41D0:2:3B9c::4/64
post-up ifconfig eth0 inet6 add 2001:41D0:2:3B9c::5/64
    post-up /sbin/ip -family inet6 route add 2001:41D0:2:3Bff:ff:ff:ff:ff dev eth0
    post-up /sbin/ip -family inet6 route add default via 2001:41D0:2:3Bff:ff:ff:ff:ff
    pre-down /sbin/ip -family inet6 route del default via 2001:41D0:2:3Bff:ff:ff:ff:ff
    pre-down /sbin/ip -family inet6 route del 2001:41D0:2:3Bff:ff:ff:ff:ff dev eth0
pre-down ifconfig eth0 inet6 del 2001:41D0:2:3B9c::1/64
pre-down ifconfig eth0 inet6 del 2001:41D0:2:3B9c::2/64
pre-down ifconfig eth0 inet6 del 2001:41D0:2:3B9c::3/64
pre-down ifconfig eth0 inet6 del 2001:41D0:2:3B9c::4/64
pre-down ifconfig eth0 inet6 del 2001:41D0:2:3B9c::5/64

not sure if its right, but it works.
