    I am having problems getting networking to start up on boot. I can get
    it running manually, but it seems like there is an interface problem
    between ifup/down and ifconfig.

    I am running net-tools (ifconfig) 1.60.8 and ifupdown 0.6.4-4.6 but have
    also tried this with net-tools 1.60.4 and ifupdown 0.5.4-4

    After bootingthe system, there are no network interfaces setup. If I
    manually run ifup -av I get the following output:

    Configuring interface lo=lo (inet)
    run-parts /etc/network/if-pre-up.d
    ifconfig lo 127.0.0.1 up
    ifconfig: only one address allowed for interface `lo'
    Usage: ifconfig [OPTION]... [SYSTEM OPTION]...
    Try `ifconfig --help' for more information.
    Configuring interface eth0=eth0 (inet)
    run-parts /etc/network/if-pre-up.d
    pump -i eth0
    run-parts /etc/network/if-up.d

    However networking comes up fine if I issue the commands:
    ifconfig lo up 127.0.0.1
    pump -i eth0

    Similarly, if I try ifdown -av I get:

    Configuring interface lo=lo (inet)
    run-parts /etc/network/if-down.d
    ifconfig lo down
    ifconfig: can not resolve `down': Unknown host
    Configuring interface eth0=eth0 (inet)
    run-parts /etc/network/if-down.d
    pump -i eth0 -k
    ifconfig eth0 down
    ifconfig: can not resolve `down': Host name lookup failure

    With regards to the boot sequence, in /etc/rcS.d I have:

    lrwxrwxrwx 1 root root 18 Dec 8 07:31 /etc/rcS.d/S40ifupdown -> ../init.d/ifupdown
    lrwxrwxrwx 1 root root 20 Dec 8 07:31 /etc/rcS.d/S40networking -> ../init.d/networking

    I tried searching bugs and the changelogs for ifconfig and ifupdown and
    the forum archives but didn't see anything relavent.

    Anyone have any ideas where/what to look at next.

    TIA,
    Lou
