+# VNC - Virtual Network Computing.  Also known as RFB - Remote Frame Buffer
+# Pattern quality: good fast
+# http://www.realvnc.com/documentation.html
+# 
+# This pattern has been verified with vnc v3.3.7 on WinXP and Linux
+# Please report on how this pattern works for you at
+# l7-filter-developers@lists.sf.net .  If you can improve on this pattern,
+# please also post to that list. You may subscribe at

+# Thanks to Trevor Paskett <tpaskett AT cymphonix.com> for this pattern.

+# Assumes single digit major and minor version numbers 
+# This message should be all alone in the first packet, so ^$ is appropriate
+^rfb 00[1-9]\.00[0-9]\x0a$
+
+# This is a more restrictive version which assumes the version numbers
+# are ones actually in existance at the time of this writing, i.e. 3.3,
+# 3.7 and 3.8 (with some clients wrongly reporting 3.5).  It should be
+# slightly faster, but probably not worth the extra maintenance.
