  7. # This should match both Gnutella and "Gnutella2" ("Mike's protocol")

  9. # Various clients use this protocol including Mactella, Shareaza,
  10. # GTK-gnutella, Gnucleus, Gnotella, LimeWire, iMesh and BearShare.

  12. # This is tested with gtk-gnutella and Shareaza.

  18. # The first part matches UDP messages - All start with "GND", then have
  19. # a flag byte which is either \x00, \x01 or \x02, then two sequence bytes
  20. # that can be anything, then a fragment number, which must start at 1.
  21. # The rest matches TCP first client message or first server message (in case
  22. # we can't see client messages). Some parts of this are empirical rather than
  23. # document based. Assumes version is between 0.0 and 2.9. (usually is
  24. # 0.4 or 0.6). I'm guessing at many of the user-agents.
  25. # The last bit is emprical and probably only matches Limewire.
