SolutionThose are different states of sockets. The LISTEN means that a process has a socket open and is waiting for something to come along and connect. The ESTABLISHED is a socket that is connected. The CLOSE_WAIT and FIN_WAIT_2 states are what you see on each end of a socket when they are in the process of closing. Often they will get hung in this state if one side or the other is not sending an acknowledgement.
Here is a link to a document that briefly lists the states.

I hope that helps a little. I gave a ten cent explanation to a ten dollar question. :)

Re: Output from netstat -a
Check out this link:

Also, do a search on netstat in the technical knowledge base. I has postings on each, like "What does CLOSE_WAIT state mean?" and so on.
Hope this helps

Re: Output from netstat -a
ESTABLISHED indicates a connection is active.
CLOSE_WAIT and FIN_WAIT* indicate a connection is being closed or has been closed recently. The protocol stack is waiting to verify no more packets will arrive on the connection.
I think SYN_SENT occurs during startup.
