CheckPoint R65 ndb_open: database ‘magic number’ corrupted(/opt/CPsuite-R65/fw1/database/fwauth.NDB) error
An irritating error which must be a bug, but only comes around every so often.
Anyway the fix is as follows:
login to the box and ensure you are in expert mode.
mv fwauth.NDB fwauth.corrupt
Reinstall your firewall policy and you should now see it sucessfully install and recreate the fwauth.NDB database.
