    i am new to this forum and i need some help. I upgraded the firmware in my nslu box and now it just sits there on the network and is not accesible from anywhere. It does not take an ip, it can not upgraded and i haven't found any way to get it to work. I was thinking of a way to upgrade it through usb but i haven't found any way to do it. Can u provide any help?

    What firmware did you load? I recall that with Linksys firmware the default IP address is (your PC must be in same range) and that Telnet is disabled until enabled through the web interface.

    only unslung firmware has web interface,its based on original firmware,if you flashed it with something else,you have to acces it with ssh,if you flashed it to unslung you can't upgrade it trough web interface anymore you have to use upslug
    or oher apps for flashing it.

    aand if you just upgraded original firmware you can use upslug to return the old firmware or try new again.

    i used openslug, can't get access though ssh either. Have scanned with nmap but i see just ports
    SCRIPT ENGINE: Initiating script scanning.
    Host appears to be up ... good.
    Interesting ports on
    Not shown: 1710 filtered ports
    135/tcp closed msrpc
    137/tcp closed netbios-ns
    138/tcp closed netbios-dgm
    139/tcp closed netbios-ssn
    no web interface sorry
    could a crossover cable and the eraseall utility be able to solve the problem and return the original firmware?

    in the link you entered it says something about JTAG. JTAG i suppose is recovery hardware and probably costs more than the whole nslu. I am still on warranty. Should i send it for repair or substitution? Is there any other option? Eraseall is out of the question. What about sercomm utility and a crossover cable? Is it possible to work?

    I have successfully used the sercomm utility before, but the slug was working before (and still is now!)
