+SMB/CIFS decoding
+.LP
+tcpdump now includes fairly extensive SMB/CIFS/NBT decoding for data
+on UDP/137, UDP/138 and TCP/139. Some primitive decoding of IPX and
+NetBEUI SMB data is also done. 
+
+By default a fairly minimal decode is done, with a much more detailed
+decode done if -v is used. Be warned that with -v a single SMB packet
+may take up a page or more, so only use -v if you really want all the
+gory details.
+
+If you are decoding SMB sessions containing unicode strings then you
+may wish to set the environment variable USE_UNICODE to 1. A patch to
+auto-detect unicode srings would be welcome.
+
+For information on SMB packet formats and what all te fields mean see
+www.cifs.org or the pub/samba/specs/ directory on your favourite
+samba.org mirror site. The SMB patches were written by Andrew Tridgell

+.RE
+In the first line, host elvis sends a RX packet to pike.  This was
+a RX data packet to the fs (fileserver) service, and is the start of
+an RPC call.  The RPC call was a rename, with the old directory file id
+of 536876964/1/1 and an old filename of `.newsrc.new', and a new directory
+file id of 536876964/1/1 and a new filename of `.newsrc'.  The host pike
+responds with a RPC reply to the rename call (which was successful, because
+it was a data packet and not an abort packet).
+.LP
+In general, all AFS RPCs are decoded at least by RPC call name.  Most
+AFS RPCs have at least some of the arguments decoded (generally only
+the `interesting' arguments, for some definition of interesting).
+.LP
+The format is intended to be self-describing, but it will probably
+not be useful to people who are not familiar with the workings of
+AFS and RX.
+.LP
+If the -v (verbose) flag is given twice, additional information is printed,
+such as the the RX call ID, call number, sequence number, serial number,
+and the RX packet flags.
+.LP
+If the -v flag is given again, the security index and service id are printed.
+.LP
+Error codes are printed for abort packets, with the exception of Ubik
+beacon packets (because abort packets are used to signify a yes vote
+for the Ubik protocol).
+.LP
+Note that AFS requests are very large and many of the arguments won't
+be printed unless \fIsnaplen\fP is increased.  Try using `\fB-s 256\fP'
+to watch AFS traffic.
+.LP
+AFS reply packets do not explicitly identify the RPC operation.  Instead,
+\fItcpdump\fP keeps track of ``recent'' requests, and matches them to the
+replies using the call number and service ID.  If a reply does not closely
+follow the
+corresponding request, it might not be parsable.
