    It fail with what error?
    Try to replace or deactivate the ethernet card that generate the failure.

    You can either rectify the source of the error. If the ethernet connection is not connected and it is configured to get it's details by DHCP, then it will wait until it times out.

    In /etc/sysconfig/network-scripts/ifcfg-eth0 (and ifcfg-eth1) you probably have an entry like:


    If it said 'static', then there would be additional entries relating to the configuration of the eth interface, and you wouldn't have the timeout associated with DHCP which is causing your current delays.

    As this problem is on boot, you can either enter an additional line in these files:


    (or change the current line to be no rather than yes). This will stop the ethernet starting at boottime, and you will have to enable then manually later:

    ifconfig eth0 up

    man ifconfig for more details.....or /etc/init.d/network restart (depending on linux distro)

    It sounds like the adapters are trying to find a DHCP server. If there is no DHCP server then you may want to stop the dhcpcd daemon or configure the nics for a static ip.

    Without any more information, I would suppose that eth0 and eth1 are configured with DHCP. When the interface is brought up it has no IP address and broadcasts messages hoping that a DHCP server will respond to. It waits for a given timeout and if it has received no response, it just brings up the interface with a "default" IP address.

    I've never used mandriva linux myself so I don't know where the configuration files are. On Debian based distributions it is in /etc/network/interfaces. Change the interface type from "dhcp" to "static" and add the address, netmask, and gatweway lines, and your done.
