I work at a service center, and am looking for a quick and easy way to test ethernet, usb, and modem ports. My management won't shell out the cash to buy the expensive proffessional sets, and I sure as heck won't. Is there any way to modify a cable to be a loopback cable, and are there any scripts (XP or Linux) that can test an ethernet, modem, or USB port for funtionality?
I would appreciate specific directions, a link to an online tutorial, or even a book recommendation.
