You could demonstrate this by:

[root at abc ~]# service smb stop
[root at abc ~]# netstat -ln > netstat-ln-smb.before
[root at abc ~]# service smb start
[root at abc ~]# netstat -ln > netstat-ln-smb.after
[root at abc ~]# diff netstat-ln-smb.*

and do it for other services by changing "smb" to something else.

Good luck,
