Kerio Personal Firewall

[Chee%2dHeng Chin <chchin () iastate edu>]

Hello list,
           I am trying to configure Kerio Personal Firewall and this firewall 
allows me to specify explicitly which service is allowed inbound/outbound 
connection thru either TCP/UDP including the exact port numbers and IP range to 
respond to. 

My question is: Is there a software/utility that will tell me exactly which 
service/application is currently listening on exactly which TCP/UDP port number?

"netstat -a" only lists the active listening ports but doesnt tell me which 
service/application is listening on that port for incoming packets.

I would like to "lock down" the server as much as possible by specifying 
exactly which port and service a connection is allowed. Thanks in advance.

Regards,

chchin
