You can configure replay detection in Java components (which includes the CLC, UFS, OSG, Walrus, and SC) to allow replays of the same message for a set time period.
If you set this property to 0, Eucalyptus will not allow any message replays. This setting provides the best protection against message replay attacks.
If you set this property to any value greater than 15 minutes plus the values of ws.clock_skew_sec (that is, to a value >= 920 sec in the default installation), Eucalyptus disables replay detection completely.
