# check-decode -- Shell script to test ike-scan packet decoding
#
# Author: Roy Hills
# Date: 02 January 2007
#
# This script checks that ike-scan decodes and displays IKE packets correctly
# It uses the undocumented ike-scan option --readpktfromfile to read the
# packet from a file rather than from the network.
#
# The packet data files contain example responses from various VPN servers.
# In each case the initiator cookie is set to "deadbeefdeadbeef", so we
# specify this to ike-scan to ensure that the packet will be matched and
# displayed.
