[COLUG] Testing Cat5e

[Mike Harrold]

Hi,

I have cat5e all over my house all coming down to the basement where
the switches and router sit.  At some point in time, some of the labelling
has detached from the cables in the basement so I am unsure of what
came from where.  I am now, of course, trying to hook up a connection
from an area whose label is on the floor.  I thought I had narrowed it
down to 2 possibilities, but it appears as I was wrong as neither work.

What is the simplest/cheapest way of testing the basement end if I have,
for example, a constant "ping" running on the computer that I am trying
to hook up?  At this point I just need to figure out which cable it is (and
for that matter, all the others so I can relabel them).

TIA!
