  1. [9fans] ip/ipconfig returns 'recved dhcpnak on /net'

    Hi,

    problem is a described in the subject. Also using a more explicit call:


    'ip/ipconfig -g 192.168.0.1 /net/ether0 192.168.0.4 255.255.255.0'

    produces the same result. 192.168.0.4 is the address the router usually asigns to the box with Plan 9 on

    The gateway is a Netgear hard firewall and router, which is bridged into by a adsl modem.

    a search for the mac address with 'cat /net/ether0/addr' just produces 0000000000000

    Could this be why the dhcp server is refusing to give out an address? How to correct this?

    I am running the Live CD (most recent version).

    Thanks,

    Alasdair

    my guess is that the driver for youor nic is failing to set
    the mac addr.

    you can^wshould be able to verify that this is indeed
    the problem by setting

    ether0=type=xyx ea=003003040506

    in your plan9.ini. what type of card do you have? i wonder if
    it is resetting properly.

    is this really what you typed? it's wrong.

    ip/ipconfig -g 192.168.0.1 ether /net/ether0 192.168.0.4 255.255.255.0

    you did not put in the ether mediatype.

    well, that is 'bad'.

    it can happen however, with certain stupid motherboards that put the
    ether mac into CMOS. I've had it happen. The BIOS very happily jams
    the garbage MAC address into hardware. Erik's suggestion is a good
    one. It would sure be helpful if you could show us more about your
    hardware.
