[LARTC] routing- multiple net provider, tcp logging

[Pawel Zawora]

Hi all,
Is any way to logs tcp connection (not packets)? something like this: 
src_IP dst_Ip, srcPort, dst_port bytes_send bytes_received?
Any netfilter extension?


2 issue:
                                   eth0------- connection 1
NET ---------gw  (linux)
                                  eth1--------connection 2

Real bandwitch on connection 1 and connection 2 is depend on different 
things (ie weather)
How to detect that connection 1 is loosing i.e. 50% packet (or real 
bandwitch is less than ...) and based on this change routing?



Thanks for  ANY help.

Pawel Z

You should probably look at some NetFlow based solution. F.e.
softflowd, netams, fprobe, etc.
