  1. How to stop 2 default gateways?

    I have two network cards, one is on a 71.252.x network and one on a
    192.168.x network. I would like my default gateway to be the 71.252.x
    with only 192.168.x traffic going through that particualr card. When I
    setup /etc/network-scripts/ifcfg-eth0 and eth1 then ifup I get two
    0.0.0.0 gateways - How can I stop Mandriva doing that?

    The device below should ONLY route to 192.168.168.254
    [root@cartman network-scripts]# more ifcfg-eth0
    DEVICE=eth0
    BOOTPROTO=static
    IPADDR=192.168.168.9
    NETMASK=255.255.255.0
    GATEWAY=192.168.168.254
    ONBOOT=yes
    METRIC=1
    MII_NOT_SUPPORTED=no
    USERCTL=no
    DNS1=71.252.202.195
    RESOLV_MODS=yes
    IPV6INIT=no
    IPV6TO4INIT=no

    Everything else should route through this card
    [root@cartman network-scripts]# more ifcfg-eth1
    DEVICE=eth1
    BOOTPROTO=static
    IPADDR=71.252.202.195
    NETMASK=255.255.255.0
    GATEWAY=71.252.202.1
    ONBOOT=yes
    METRIC=10
    MII_NOT_SUPPORTED=yes
    USERCTL=no
    DNS1=71.252.202.195
    DNS2=4.2.2.2
    RESOLV_MODS=yes
    LINK_DETECTION_DELAY=6
    IPV6INIT=no
    IPV6TO4INIT=no


    However there are two default routes.
    [root@cartman network-scripts]# netstat -rn
    Kernel IP routing table
    Destination Gateway Genmask Flags MSS Window irtt Iface
    71.252.202.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
    192.168.168.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
    169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
    169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1
    127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
    0.0.0.0 192.168.168.254 0.0.0.0 UG 0 0 0 eth0
    0.0.0.0 71.252.202.1 0.0.0.0 UG 0 0 0 eth1

    Any idea how I can fix this using the scripts or should I write my own
    to start eth0 after eth1 if configured?

    Just remove the above line.

    You may also want to add a zeroconf line to /etc/sysconfig/network

    $ cat /etc/sysconfig/network
    NETWORKING_IPV6=no
    NOZEROCONF=yes <===== line to add.
    NEEDHOSTNAME=no
    NETWORKING=yes
    HOSTNAME=wm81.home.test

    Thanks, I'll give that a try.

    Try removing the above line.

    My some odd freak of computing, whenever I traceroute a site it goes out
    the 71.x network card and only 192.168.x does out that particular card.
    Quite unexpected but works for me, not a proper solution tho.
