+	  --------
+	  FOREWORD
+	  --------
+			   
+The patch in this folder allows Wireshark to process packets that contain TLS-protected
+Diameter messages over SCTP multi-stream associations. Each SCTP stream pairs is handled
+as a separate TLS channel (RFC3436), which is consistent with freeDiameter 1.0.x mechanism.
+
+It should be noted however that rfc3588bis (revised Diameter) recommends that DTLS is used
+instead of TLS over SCTP, for the reasons highlighted in the introduction of RFC6083.
+When this new mechanism is implemented in freeDiameter, a different patch will probably
+be required for wireshark.
+
+
+The instructions in this file will change your wireshark binary in a way suitable for
+analysis of Diameter over TLS over SCTP, but may have unexpected side-effects
+on some other protocols analysis (including DTLS).
+
+The instructions refer to Debian-style packaging (apt), you should adapt 
+the process to build a new modified package of wireshark for your distribution.
+
+The provided patch has been successfully tested with:
+ - wireshark-1.2.7 (Ubuntu Lucid)
+ - wireshark-1.2.11 (Ubuntu Maverick)
+It may or may not work on more recent or ancient versions.
+
+
+	------------
+	INSTRUCTIONS
+	------------
+
+The steps are:
+ - get your wireshark source
+ 	apt-get source wireshark
+	cd wireshark-1.2.*
+	
+ - apply the patch
+ 	cat ~/wireshark-1.2.7-diameter-tls.patch | patch -p1
+
+ - increase the version number
+ 	dch -lfD "Added support for Diameter over TLS over SCTP"
+	
+ - Create a new package, this might take a while
+	fakeroot debian/rules binary
+
+ - Install the modified version
+ 	sudo dpkg --install ../wireshark-common_*fD*.deb ../wireshark_*fD*.deb
+
+ - Start the new wireshark:
+ 	wireshark &
+	
+To analyze a capture file, you will need the private keys of both peers involved.
+
+Let's imagine for example:
+  peer A with IP address 192.168.0.10 has private key privA.pem
+  peer B with IP address 192.168.0.11 has private key privB.pem
+  
+In wireshark you must do the following:
+ - go to menu Edit->Preferences
+ - In the left panel, under Protocols, scroll to "SSL" and select it.
+ - In the right panel, fill "RSA keys list" as follow:
+	192.168.0.10,3869,diameter,/absolute/path/to/privA.pem;192.168.0.11,3869,diameter,/absolute/path/to/privB.pem
+ - You may find also useful to select an SSL debug file to get a hint of any problem.
+ 
+Once this configuration is complete, you should be able to see the contents of SCTP packets, 
+including protected Diameter payload.
+
+Check the "sample" subdirectory for a test capture file.

+This folder contains an example capture file, as well as the two
+private keys required to decode the TLS-protected exchanges.
+
+In order to decrypt properly the packets, you'll need a patched wireshark (see parent directory)
+and the SSL "RSA Private Keys" properties set to (replace with real full path):
+  192.168.103.10,3869,diameter,freeDiameter/contrib/wireshark/sample/192.168.103.10.priv.pem;192.168.103.20,3869,diameter,freeDiameter/contrib/wireshark/sample/192.168.103.20.priv.pem
+
+
+This capture contains everything that was exchanged by the peer since it boot up.
+The captured peer is "relay.a.rt.freediameter.net" with IP address 192.168.103.20.
+
+Here is the detail of what you can see in the capture, if the decyphering 
+works as expected, in chronological order:
+
+-----------------------------------------------------------------------------
+Frames		| Comments
+-----------------------------------------------------------------------------
+1-24		| Peer booting up: DHCP, NTP, ...
+		|
+25-29		| Connection attempt from 192.168.103.10

+		|   then on TCP (frames 28-29)
+		|
+32-35		| freeDiameter starting: Diameter Identities

+		|   where freeDiameter was not started.
+		|
+46-49		| (I think this is trigged by Debug output,

+50-73		| TLS handshake on first stream pair (#0).
+		|
+74-90		| Resumed handshakes on streams #1 and #2 in parallel.
