I still propose that you tcpdump it, then I can tell you (I know enough about Thomas' case but yours has a large number of unknowns)... :-) I don't know why 2.6.24 didn't suffer from the problem as FRTO was enabled already in it. The command you need to create dump.log file: # tcpdump -w dump.log -i <iface> host <peerip> ...you need root rights (or sudo) to do the capturing. -- i.
