Performs password guessing against databases supporting the IBM DB2 protocol such as Informix, DB2 and Derby SYNTAX: userdb: The filename of an alternate username database. drda-brute.threads: the amount of accounts to attempt to brute force in parallell (default 10). unpwdb.userlimit: The maximum number of usernames 'usernames' will return (default unlimited). unpwdb.passlimit: The maximum number of passwords 'passwords' will return (default unlimited). drda-brute.dbname: the database name against which to guess passwords (default ''SAMPLE''). unpwdb.timelimit: The maximum amount of time that any iterator will run before stopping. The value is in seconds by default and you can follow it with 'ms', 's', 'm', or 'h' for milliseconds, seconds, minutes, or hours. For example, 'unpwdb.timelimit=30m' or 'unpwdb.timelimit=.5h' for 30 minutes. The default depends on the timing template level (see the module description). Use the value '0' to disable the time limit. passdb: The filename of an alternate password database.
