title: How to know traffic to a specific port in linux
body: <p>I am looking to find the traffic through a specific port for a time frame. For example, traffic through 3306 port for 10 seconds. Is there a way to find this information?</p>
  
  <p>I see that "/sbin/ifconfig eth0 05" can be used to get information on total bytes but I am looking to find information about specific port's traffic.</p>
  
  <p>Thanks in advance,</p>
