I am writing a VNC packet dissector for Wireshark and have a few 
questions about the VNC RFB protocol.  I'm referring to 
http://www.realvnc.com/docs/rfbproto.pdf to develop this code 
and am about 3/4 of the way through.

My first question is about the Server Framebuffer Update message.  Can 
it span multiple packets?  All of the other types stay within one 
packet.  However, when my dissector comes across Server Framebufer 
Updates, the first is malformed (I'm expecting more bytes than are 
present) and the next few packets (or more) do not start with the 
standard message type field at the top, which makes me think that 
they're a continuation of the previous packet.


Thanks,
  Steve
