Suppose party A connects to the Internet via a dial-up IP server (e.g., using SLIP or PPP), has several open Telnet connections (using TCP), and is cut off. Party B then dials in and is assigned the same IP address that A had. Assuming B was able to guess to what host(s) A had been connected, describe a sequence of probes that could enable B to obtain sufficient state information to continue with A's connections.
