logging of successful tcp connections

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I would like to know if there is a way I can log only successful tcp
connections. I'm only interested in successful (established) connections,
and not just syn "connection attempts". I guess what I need is a way to log
a single packet if it caused a state transition from NEW to ESTABLISHED. It
would also be helpful to log the packet that terminated the connection
(state change from established). In this manner, we could easily tell what
connections were made, and their duration (and not rely on the userland
application to log this info).

I've looked into using the state matching, but couldn't achieve this
specific functionality with that.

 

Is there some trivial way to accomplish this I am overlooking?

 

Thanks,

Chris
