vnc
# 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.
