# 14.3. Debian Linux

Following information was contributed by Stephane Bortzmeyer <bortzmeyer at nic dot fr>

1. Be sure that IPv6 is loaded, either because it is compiled into the kernel or because the module is loaded. For the latest, three solutions, adding it to /etc/modules, using the pre-up trick shown later or using kmod (not detailed here).

2. Configure your interface. Here we assume eth0 and address (2001:0db8:1234:5::1:1). Edit /etc/network/interfaces:

    iface eth0 inet6 static
            pre-up modprobe ipv6
            address 2001:0db8:1234:5::1:1
            # To suppress completely autoconfiguration:
            # up echo 0 > /proc/sys/net/ipv6/conf/all/autoconf
            netmask 64
            # The router is autoconfigured and has no fixed address.
            # It is magically
            # found. (/proc/sys/net/ipv6/conf/all/accept_ra). Otherwise:
            #gateway 2001:0db8:1234:5::1

And you reboot or you just

    # ifup --force eth0

and you have your static address.
