log connections to a port (3700, CORBA lookup in Glassfish)

[Thufir]

Is port 3700 actually open?  It seems to be:

thufir at doge:~$ 
thufir at doge:~$ nmap localhost -p 3700

Starting Nmap 6.46 ( http://nmap.org ) at 2015-02-27 12:52 PST
Nmap scan report for localhost (127.0.0.1)

thufir at doge:~$

thufir at doge:~$ 



can I log connections to it, so that I can see the attempts by 
192.168.1.2 (tleilax) connect?  (CORBA on glassfish.)



thanks,
