    [Solved] Renalbling eth0 on 8.04 server

    A customer of mine has the following problem:

    I set up a openerp server for him on 8.04 server LTS with a kde desktop.
    It ran fine until this morning when he stopped the server and relocated it to a dfferent room.

    Upon reboot the server would not connect to eth0 wired lan.

    The set up:
    Cable modem->8 point switch-> server / Jaunty desktop / voip phone

    Network is running dhcp with the server getting its IP from:
    http://www.no-ip.com

    What I did:
    I restarted the modem then reset the switch and rebooted the server.

    Code:
    sudo ifup eth0
    gives:
    ifup: interface eth0 already configured.

    I then went and disabled the eth0 from the network manager gui and reneabled it.
    Nada.
    Reboot: nada

    I then quit network manager leaving it start automatically at boot and rebooted.
    Nada.

    /etc/network/interfaces looks normal:
    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp
    Anyone with an idea?

    My guess would be hardware, specifically, the switch, if other boxes are getting to thenet through the modem.

      Thank you askrieger I think you have a point.
      This is the switch setup:

      Switch: netgear FS108 8- port

      Port 1-> cable modem
      Port 2-> Voip phone
      Port 3-> Voip phone router with 2 lines
      Port 4-> JJ Desktop
      Port 5-> 8.04 Server
      Port 6-> empty
      Port 7-> empty
      Port 8-> empty

      When I pull the plug one the desktop and reboot the server it will connect.
      When I boot JJ with the server connected I can't get JJ to connect.

      I should still have 3 ports available

        I would try removing everything from the switch. Plug in the server first. Reboot and see if you can connect. Try plugging in JJ next and see if you can connect. Plug in the other two last, one at a time and see if you can connect. Also try using ports 5-8 first, if your switch allows this. You might have a bad cable, port, or switch. The Voip phone and Voip phone router may also be causing the problem.

        Try one at a time in that order and see what happens.
        Good Luck and keep us posted.

          Thank you for all the responses and sorry for taking so long. I was away.

          Anyway I found out that it is a hardware issue of sorts.

          Since I am on a dhcp cable modem, I called up my IP and they confirm that I only have 4 addresses assigned.

          So I have to get a small router and stick that between my modem and my switch.

          I will mark this solved for now.
