Subject: [LARTC] ACK matching
Date: Tue, 21 May 2002 20:26:22 +0000	[thread overview]
Message-ID: <marc-lartc-102201284932330@msgid-missing> (raw)

Hi,

in the LARTC-HowTo is an example given for matching packets with the
ACK-bit set.

Does "IP Total length 0x34 (ACK + 12 bytes of TCP options)" (from the
HowTo) mean that you are just matching Packets with an ACK set but
without any data? If I am right, this would mean that just
Forward-Acknowledgements are matched, isn't it?

What about matching ACKs with iptables, is it possible to mark Packets
with ACK set but without data?


bye,
Hannes
