    Nice Job! I really like that one.
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

    I wouldn't be surprised if you get packet loss with it like that. You'd want to keep it as twisted as possible and heatshrunk.

    It does look as if the wires add up to same lengths overall which is a good thing.

    oh right, i didnt know that... but it dosn't really explain why i get 100% packet loss when i connect it to the tap on 3&6? :S

    also, before i go remaking it and heatshrinking it all... is my wireing correct? or is there a better way of doing it?

    The old Ortronics 4 port wall jacks come in handy building these guys.

    Oops, heh, that's bigger than I thought it was.
    Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69

    Are you saying that the passthru fails when you plug in a NIC to the tap? If so you ned to get the card up in PROMISC mode and possibly even set it manually at half duplex if its not auto negotiating. You'd want to bond the two tap NICS has well, and just as streaker69 pointed out make sure they do not have an IP address.

    Also trim those ends on the end taps, no need to have tiny antennae on them. If your punch down tool doesn't trim, then you can use a utility knife. Hopefully you're using a real punchdown tool with impact and not one of those press fit ones.

    I know they're expensive, but I'm a firm believer in having the correct tools for the job.

    They're not too bad at home depot.
