fwtmp, wtmpfix - manipulate connect accounting records


/usr/lib/acct/fwtmp [-ic]

/usr/lib/acct/wtmpfix [file]...


fwtmp reads from the standard input and writes to the standard output,
converting binary records of the type found in /var/adm/wtmpx to
formatted ASCII records. The ASCII version is useful when it is necessary
to edit bad records.

wtmpfix examines the standard input or named files in utmpx format,
corrects the time/date stamps to make the entries consistent, and writes
to the standard output. A hyphen (-) can be used in place of file to
indicate the standard input. If time/date corrections are not performed,
acctcon(8) will fault when it encounters certain date-change records.

Each time the date is set, a pair of date change records are written to
/var/adm/wtmpx. 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 utmpx 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.

In addition to correcting time/date stamps, wtmpfix will check 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 will change the login name to INVALID and write a
diagnostic to the standard error. In this way, wtmpfix reduces the chance
that acctcon will fail when processing connect accounting records.


Denotes that input is in ASCII form, and output is to be written
in binary form.
