I've searched quite extensively for this, but cannot seem to come up with a working example.
My objective is to monitor TCP traffic on a specific port to see incoming connections and write them to a text file. The catch is I also need a timestamp on each row to show exactly when the client connected down to the second.
I've already exhausted netstat, nmap, and tcptrack, but none support timestamp.
I was thinking a linux shell script might work if I monitored a specific local port and wrote text to a file when a connection is made then just concatenate the date on each line.
I was playing with this:
netstat -ano|grep 443|grep ESTABLISHED
as well as this:
tcptrack -i eth0 port 443
but neither suit my needs as I need the time the connection comes in at.
If you have any suggestions or could point me in the right direction it would be greatly appreciated.
