Suppose client a initiates a telnet session with server s. at about the same time, client b also initiates a telnet session with server s. provide possible source and destination and source tcp port numbers for the followings transactions. use the well-known port number. make up valid tcp port numbers for client a and b.

(1) the segments sent from a to s.
(2) the segments sent from b to s.
(3) the segments sent from s to a
(4) the segments sent from s to b
(5) if a and b are in different hosts, is it possible that the source port number in the segments from a to s is the same as that from b to s?
(6) how about if they are the same host?
