Subject: [LARTC] Matching packet size
Date: Wed, 24 Jul 2002 20:08:37 +0000	[thread overview]
Message-ID: <marc-lartc-102754137016761@msgid-missing> (raw)

Hi,

In the ACK-matching example in the LARTC-HOWTO there is a line to match
all packets smaller than 64 bytes ("match u16 0x0000 0xffc0 at 2").
This sounds logical for Ethernet-devices, but what if I use a PPP-device
(as it is shown in the example)?

The Frame-Header of PPP is significant smaller than the header of
Ethernet, does this affect the matching of the relevant packets with the
ACK-bit set?

Additional question: If I want to match packets smaller than 128 bytes,
would "match u16 0x0000 0xff80 at 2" do the thing?


Regards,
Hannes
