    If you're not getting a ppp0 interface, that simply means you aren't
    connecting to your ISP. The cause could be anything from
    misconfiguration to wrong username or password, or even that the
    Ethernet cable is disconnected. So let's diagnose this.

    I'll assume that your Ethernet cable is connected and DSL modem is
    turned on (otherwise, pppoeconf would error out and exit). The problem
    could possibly be your /etc/network/interfaces file - feel free to copy
    mine:

    # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

       # The loopback interface
       # automatically added when upgrading
       auto lo eth0
       iface lo inet loopback

       iface eth0 inet static
              address 192.168.0.2
              netmask 255.255.255.0
              network 192.168.0.0
            broadcast 192.168.0.255

    If you make any changes to /etc/network/interfaces, reboot (actually you
    just need to restart the network, but rebooting is probably easier). Try
    running "pon dsl-provider" - if it doesn't work, try running it as root
    (to eliminate any possibility of a permissions error). If it's working
    properly, this is the output you should see:

    bob@sonic:~> pon dsl-provider
    Plugin rp-pppoe.so loaded.
    RP-PPPoE plugin version 3.3 compiled against pppd 2.4.2

    If it still doesn't work, please post the output of "ifconfig" and I'll
    get back to you.

    By the way, when you ran "pppoeconf", did it give you any error
    messages, or did it accept your username/password and exit without
    complaint?

    best regards,
    Robert
