- # Gnutella - P2P filesharing
- # Pattern quality: good fast
- #
- # This should match both Gnutella and "Gnutella2" ("Mike's protocol")
- #
- # Various clients use this protocol including Mactella, Shareaza,
- # GTK-gnutella, Gnucleus, Gnotella, LimeWire, BearShare, and iMesh.
- #
- # This is tested with gtk-gnutella and Shareaza.
- #
- # Please report on how this pattern works for you at
- # l7-filter-developers@lists.sf.net . If you can improve on this
- # pattern, please also post to that list. You may subscribe at

- # The first part matches UDP messages - All start with "GND", then have
- # a flag byte which is either \x00, \x01 or \x02, then two sequence bytes
- # that can be anything, then a fragment number, which must start at 1.
- # The rest matches TCP first client message or first server message (in case
- # we can't see client messages). Some parts of this are empirical rather than
- # document based. Assumes version is between 0.0 and 2.9. (usually is
- # 0.4 or 0.6). I'm guessing at many of the user-agents.
- # The last bit is emprical and probably only matches Limewire.
