list of tcp connections for particular port

Question

I need list of tcp connections made where client has particular port for example : from my linux server need to check if any connection is made with client by 8008 port of client within last two minutes..

Is this possible or I m looking for too much ..?

Are you sure you're looking for the *client* port? These are usually random. — Frédéric Hamidi, Dec 08 '15 at 09:56
Honestly, this looks like a job for `iptables`, not for a custom program, which makes your question a little off-topic here. I would advise you look around (e.g. on [sf]) for an appropriate firewall configuration. — Frédéric Hamidi, Dec 08 '15 at 10:07

You can read /proc/net/tcp for this, but it does not track history, so you need to poll it occasionally. This will work so long as you don't mind "missing" some very short-lived connections.
