Connection uptime

[Gaston Martres]

Hi there.

    Is there a way to know the uptime of a connection? Or the time 
remaining for the timeout for a SYN, for example? All of this done with 
netfilter or iptables, or to implement them by knowing this things with 
another tool.

The idea came by a post on the suse-security announce, but I'm curious 
to know if it's doable.

Thanks.
