Now the patch is accepted. So you don't have to apply the patch
by yourself. However, you have to build by yourself.

For trying the patch:

     (1) install autotools, svn, gcc and pcap library to your system.
     (2) do 
     	 $ svn co http://anonsvn.wireshark.org/wireshark/trunk/ wireshark
     (3) do
         $ cd wireshark; ./autogen.sh; ./configure; make; ./wireshark
     (4) touch /mnt-where-gfs-is-mounted/something-file

If GUI labels explaining the protocol is broken or not good, 
please, let me know. 


Which protocol you want to dissect next?
totem? udp:5405 may be the target.

    # Please read the openais.conf.5 manual page

    totem {
	    version: 2
	    secauth: off
	    threads: 0
	    interface {
		    ringnumber: 0
		    bindnetaddr: 192.168.2.0
		    mcastaddr: 226.94.1.1
		    mcastport: 5405
	    }
    }

    logging {
	    debug: off
	    timestamp: on
    }

    amf {
	    mode: disabled
    }


I'd like to provide dissectors for all protocols used in RHCS and
GFS. The dissectors may be useful for shooting troubles and
understanding the software.  However, I have limited time to hack, so
I have to prioritize protocols. Inputs are welcome.

Thanks,
