  • Where's the documentation?

    From Nick Jacobs@21:1/5 to All on Sun May 13 16:20:01 2018
    Can someone point me to good, correct documentation on how to configure IPv6 in Debian stable and oldstable?

    A lot of people seem to have problems configuring IPv6 of Debian, with the main symptom being that a program trying to use IPv6 times out and falls back to IPv4. Googling for solutions reveals a surprisingly large number of people who have basically
    given up and resorted to disabling IPv6 completely.

    Looking in /etc/network, there is a file called "interfaces" which has at the top:


    # This configuration file is auto-generated.# WARNING: Do not edit this file, otherwise your changes will be lost.
    # Please edit template /etc/network/interfaces.template instead.


    But there isn't any file /etc/network/interfaces.template !



    I'm using oldstable ( Jessie, Debian 8.10).

    That last bit should state "in the stanza of `iface eth1 inet
    static`". I see I missed a mandatory argument to `ip` as well.

    Like so:

    ```
    inet eth1 iface static
    address 192.168.1.2/24
    gateway 192.168.1.1
    up ip -6 addr add fec0::3/64 dev eth1
    up ip -6 route add default via fec0::1
    ````

    Have a look at `man 5 interfaces`:

    ```
    EXAMPLE
    The following example configures two network interfaces: eth0
    is brought up at boot, and uses DHCP for IPv4 and SLAAC for IPv6,
    whereas eth1 is brought up whenever the network hardware is detected,
    and is configured with static IPv4 and IPv6 addresses.
    auto eth0
    allow-hotplug eth1

    iface eth0 inet dhcp

    iface eth0 inet6 auto

    iface eth1 inet static
    address 192.168.1.2/24
    gateway 192.168.1.1

    iface eth1 inet6 static
    address fec0:0:0:1::2/64
    gateway fec0:0:0:1::1
    ```

    Another possibility is to use `up ip -6 addr add fec0::3/64` and `up
    ip -6 route add default fec0::1` in the stanza of `inet eth1 inet
    static`.

    Best,

    Mostly, there is nothing to do.
    Hosts auto-configure addresses and default routes.

    Sounds like they have a problem with their router, rather than with their
    host. Their are getting RAs from a router, but are not really connected.

    So, I'd be glad to help, but I don't think the problem is with Debian.
