Kovar Subject: Telephone line security To: security@rutgers.edu I was tracing the phone wires in my house yesterday afternoon trying to find out why my phone was "off-hook" when all of the phones were actually hung up. Just before the lines enter my house I found a gray box labelled "Telephone Network Interface". Curious, I opened the box to find two RJ-11 modular phone jacks with black connectors in them that were held in by clips. I popped the clip, unplugged the plugs and plugged in a normal phone. Lo and behold, a dial tone! I wandered around the neighborhood a bit and found a few more of these boxes. Looks like you can wander around Boston with a phone, plug into someone's circuit, and make as many phone calls as you like. Who needs lineman's equipment? -David C.
