RE: [PLUG] Bridging two networks using linux


You'll love this one.  Pre-depression era house?  What wires and maybe
even gaslines still exist in the walls and floors between you and your
object?  I found all sorts of weird impedimenta including the original
water lines and even the lines for gas lighting no longer used but fully
charged.  And what was used to hold the plaster up?  If the house is just
pre-depression, someone could have used chicken wire to solve the problem
caused by the, to them, novel problem that there was no more steady supply
of horsehair.
