    Configuring Ubuntu Networking (cant ping gateway)

    Hello, im new using Linux. I already download the file Linux Ubuntu 5.04.ISO and install in my pc using router. I just install Linux Ubuntu in 1 pc for test.
    Code:
    Using ZXDSL 831 (Router)
IP Adress = 192.168.1.10
Gateway = 192.168.1.1
DNS = 202.138.128.50, 202.138.28.28
    im have 2 PC Winxp OS and 1 Linux Ubunte but Linux Ubunte cant connect to Internet and cant Ping other PC together with the Gateway (router).
    The lan card detected and installed.

    Code:
    #ifconfig

eth0
Link encap:Ethernet HWaddr 00:08:A1:7E: D0:04

iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
gateway 192.168.1.1

auto eth0
    I already set my LAN, My Windows are doing fine for network but my Ubunte Pc wasnt ping the Gateway(192.168.1.1) only my ubuntu can ping himself.

    i try

    Code:
    sudo ifup eth0
ifup: interface eth0 already configured
    When i try this PING:

    Code:
    ping -c 3 127.0.0.1

    Do i have to change the setting in my ROUTER?
    Is there other settings messed up?

    Any reply is appreciated...

    the router should be fine no changes needed
    this might be a case of the module for the nic not being loaded on boot
    could you faste the output of:
    Code:
    lspci
    and
    Code:
    lsmod

    actualy i found that a common problem with this card is that you cant use 'acpi' with it so add this to your kernel line in grub open your favorite editor something like this
    Code:
    sudo gedit /boot/grub/menu.lst
    and add this with a space to the end of the kernel line
    Code:
    pci=noacpi
    and this should fix it if not stop back...since i dont realy know that u have the offending card yet but this is common with cards that use this driver/module
    then reboot....
    also look at this this info was gleened from this http://ubuntuforums.org/showthread.php?t=54886

    Great! Now its all working properly, turn off the ICMP response in your gateway for security reasons. Script kiddies then cant tell if your server is there by pinging it.
