you can get informations as,

# netstat -ivn

what do you require from that input? Post with details more.

Have you tried iptraf? This should give you the info you need in real time. If you don't have it and are running any form of RH (i.e. Fedora, RHEL & any of the white box derivatives) then you can install it using yum.
