    Hi,

    I'm looking for a way to set an interface UP using /etc/rc.conf
    without giving the interface an IP-address (i.e. neither static nor
    DHCP)

    Background: The machine in question has three Ethernet-IFs - one
    connects to the LAN (and has an IP-address) the other two are used for
    monitoring traffic via ethereal only. For security reasons I don't
    want to assign IP-addresses to the two "ethereal-only" interfaces -
    but I need them "UP".

    Sure enough I can "up" these interfaces manually but I want them up at
    boot-time.

    I've tried with entries like e.g.

    ifconfig_fxp1=""
    ifconfig_fxp1="UP"

    in my /etc/rc.conf - none of these work.

    So what should I configure in /etc/rc.conf in order to get the
    interfaces UP?

    BTW - ethereal only recognizes interfaces that are in the "UP" state.

    Thanks much in advance for any clue,
    -ewald
