There are tools like openports or the sysinternals set you may
Windows: netstat -aon
Linux: netstat -apn
Of course all these tools only work if the application uses the OS'es IP
stack. Any decent rootkitted malware, that puts it's on packets on the
wire and sniffs the responses promiscuously, won't show up in those
lists. You can see the packets with tcpdump/sniffers, but won't be able
to correlate them back to an application (unless you do some CPU
utilization sample and correlate that with the observed network traffic,
but you'd need to be able to see the app in the first place, so if it's
hidden by a rootkit, that won't help you either).
Just because nothing shows up in netstat doesn't mean that there isn't
an application promiscuously listening for data to that port.
