Usage

usage: fwaudit [options] file [...]
options:
 -help       - show usage (this list)
 -o filename - write binary audit output to file (- for stdout)
 -c comment  - write clear-text comment into binary audit file
 -e expr     - specify filter expression
 -f filename - read filter expression from file
 -r          - print clear-text report
 -m          - print MEMO records
 -i number   - print values of the first 'number' items
 -I itemlist - print values of specified items (comma- or space-separated)
 -v          - print progress info / report details (-vv: more details)
 -x          - clear-text diagnostic output (hexdump format)
 -M          - use master key
 -Z          - compress audit file 

If multiple forward-log files are specified, fwaudit automatically recognizes their volume generation and sequence numbers and sorts them appropriately so that they are processed in the correct order. This is done by reading the file headers, therefore this works even if the file names do not indicate the generation and sequence.

The options are:

The -o option may be used to specify the name of an output file. If present, the audit information is written to this file encoded in the Eloquence binary audit format. A - as the output file name specifies the standard output.

If an output file is created, the -Z option may be used to write a compressed output file (gzip compatible). When reading audit files with fwaudit, the compressed format is detected automatically.

If an output file is created, the -c option may be used to write an user-defined comment to the beginning of the file, for example to include a label that may later be helpful to associate the file's creator.

The -e and -f options allow to specify one or more filter expressions to qualify the information which is output. This affects both the information written to an audit file as well as any clear-text output.

The -r option activates the clear-text reporting to analyze the contents of forward-log or binary audit files. It may be combined with the -i, -I and -v options to specify the level of detail:

• If the -r option is specified alone (that is, neither -i nor -I nor -v are specified), the DBPUT, DBUPDATE or DBDELETE actions are printed indicating the data set, record number, timestamp and session number they belong to. Whenever a new session number occurs, the associated session sign-on record is printed which indicates the session's client process information.

• The -i option specifies the number of item values which should be printed for each action (DBPUT, DBUPDATE or DBDELETE) in addition. For example, -i3 specifies that in addition to the -r output the first three item values should be printed.

• The -I option allows to specify a list of item names which values should be printed for each action in addition. For example, -I 'custno, matchcode, name' specifies that in addition to the -r output the values of the CUSTNO, MATCHCODE and NAME items should be printed if they are part of the particular data set.
  If a single array element should be printed, specify the 1-based element index in square brackets. For example, the first element in the TURNOVER array is specified as TURNOVER[1]. To specify that all elements of an array should be printed, use the array item name, for example TURNOVER.

• For DBUPDATE, if -i or -I is specified modified item values are always printed regardless whether they are covered by the -i or -I specification. For example, if you specify -i1 but the value of the third item was modified its old and new values are printed.

• If the -r option is not specified, the -i and -I options have no effect.

• If the -v option is specified alone (that is, -r is not specified) the progress is indicated by printing the name of each processed file. Specifying -v twice (-vv) prints additional file header detail information.

• If both the -v and -r options are specified, the values of all items are printed for each action unless the items to be printed are qualified with -i or -I.

The -m option activates clear-text output of TurboIMAGE DBMEMO and DBBEGIN/DBEND records, which may have been recorded depending on the HP3K_API_COMPAT database property.

• TurboIMAGE DBMEMO and DBBEGIN/DBEND record data is output in clear text by default. Any non-printable characters are printed as octal escape sequences (the same way item values are output). The -x option allows to switch to a hexdump output format instead.

• The -m option may be combined with the -r option (print clear text report).

If neither -o nor -r nor -v nor -m are specified, fwaudit just silently checks the forward-log or binary audit files for consistency and prints any error or warning messages to the standard error output.

Filter Expressions

• To extract a subset of the original information from either forward-log or binary audit files to a new binary audit file
• To create a clear-text report about specific actions in a database from either forward-log or binary audit files

Filter expressions follow a syntax that allows to specify different categories:

• filter by timestamp
• filter by the type of database operation (dbput, dbupdate, dbdelete)
• filter by database and data set
• filter by record number
• filter by process specific information (e.g. user, pid, or program name)
• filter by item value
• filter by session identifier
• filter by session connection timestamp
• filter by TurboIMAGE DBMEMO and DBBEGIN/DBEND information

Find details and examples on using filter expressions in the Eloquence B.08.10 document on Database Auditing.

Database Encryption

The fwaudit -M option is used with encrypted forward logs. When specified, the EQ_MKEYID and EQ_MKEYFILE environment variables are used to provide master key(s) to access encrypted data. The user is prompted to enter the pass-phrase(s).

• EQ_MKEYID specifies a colon separated list of master key id's. Up to 6 master key id's may be present.
• EQ_MKEYFILE specifies a colon separated list of master key files. Up to 3 key files may be specified. The default key file is eqdb.key.

For example:

$ export EQ_MKEYID=alpha:beta
$ export EQ_MKEYFILE=test.key

$ fwaudit ... -M ...
Enter passphrase for alpha:
alpha: Master key activated
Enter passphrase for beta:
beta: Master key activated
 ...

Note that using fwaudit on forward logs with encrypted data is also possible without specifying the -M option and master keys. However, this only grants access to the items that are not encrypted. For all encrypted items, fwaudit will only display blank or zero values.
