 NAME
      fwtmp, wtmpfix - manipulate connect accounting records

 SYNOPSIS
      /usr/sbin/acct/fwtmp [-ic]

      /usr/sbin/acct/wtmpfix [files]

 DESCRIPTION
    fwtmp
      fwtmp reads from the standard input and writes to the standard output,
      converting binary records of the type found in wtmp to formatted ASCII
      records.	The ASCII version is useful to enable editing, via ed(1),
      bad records or general purpose maintenance of the file.

      The argument -ic is used to denote that input is in ASCII form, and
      output is to be written in binary form.  (The arguments i and c are
      independent, respectively specifying ASCII input and binary output,
      thus -i is an ASCII to ASCII copy and -c is a binary to binary copy).

    wtmpfix
      wtmpfix examines the standard input or named files in wtmp format,
      corrects the time/date stamps to make the entries consistent, and
      writes to the standard output.  A - can be used in place of files to
      indicate the standard input.  If time/date corrections are not
      performed, acctcon1 will fault when it encounters certain date-change
      records.

      Each time the date is set, a pair of date change records is written to
      /var/adm/wtmp.  The first record is the old date denoted by the string
      old time placed in the line field and the flag OLD_TIME placed in the
      type field of the <utmp.h> structure.  The second record specifies the
      new date, and is denoted by the string new time placed in the line
      field and the flag NEW_TIME placed in the type field.  wtmpfix uses
      these records to synchronize all time stamps in the file.	 wtmpfix
      nullifies date change records when writing to the standard output by
      setting the time field of the <utmp.h> structure in the old date
      change record equal to the time field in the new date change record.
      This prevents wtmpfix and acctcon1 from factoring in a date change
      record pair more than once.

      In addition to correcting time/date stamps, wtmpfix checks the
      validity of the name field to ensure that it consists solely of
      alphanumeric characters or spaces.  If it encounters a name that is
      considered invalid, it changes the login name to INVALID and write a
      diagnostic to the standard error.	 This minimizes the risk that
      acctcon1 will fail when processing connect accounting records.

 DIAGNOSTICS
      wtmpfix generates the following diagnostics messages:




 Hewlett-Packard Company	    - 1 -   HP-UX Release 11i: November 2000






 fwtmp(1M)							   fwtmp(1M)




	   Cannot make temporary: xxx failed to make temp file
	   Input truncated at offset: xxx missing half of date pair
	   New date expected at offset: xxx missing half of date pair
	   Cannot read from temp: xxx some error reading
	   Bad file at offset: xxx ut_line entry not digit, alpha, nor | or { (first character only checked)
	   Out of core: malloc fails. (Saves table of date changes)
	   No dtab: software error (rarely seen, if ever)
