[SLUG] Too many ethx ports

[Gerald <gcsgcatling@xxxxxxxxxxx>]

Hi Guy's,
        How can I get rid of eth1,eth2,and just keep eth0. with no
        references to
        the other ports?
        The system is very confused and will not send/receive email with
        all the
        network ports. 
        The reason for the number of ports is because I tried a wireless
        network
        when the on board 1GB network failed that was eth0, then the
        wireless
        becane eth1 the next trail wan a 1GB Intel network card that
        became
        eth2.
        Now I want to get rid of eth0,eth1,eth2 then have eth0 only.
        The question is HOW?
        Many thanks in advance
        Gezza
