How can I see if a machine tried to connect to my (linux) server or not? [closed]

I am trying to connect to a linux server which has several listening ports, and my connections are failing (According to my client) because the "host is down" ... however, I know the host is up. So is there a script or log file I can change/inspect to see the rejected connection on the server side ... better yet, see WHY the connection is failing ? In general, I find that connection failures can have misleading or ambiguous error messages... So I think this will solve my connection debugging activities once and for all, so that I will be able to directly test if the end point is rejecting a connection on the actual server side, rather than guessing based on client error messages. BTW this is related to hadoop.
