fwtmp(1M)fwtmp(1M)NAME
fwtmp, wtmpfix - manipulate connect accounting records
SYNOPSIS
/usr/lib/acct/fwtmp [-ic]
/usr/lib/acct/wtmpfix [files]
DESCRIPTION
fwtmp reads from the standard input and writes to the standard output,
converting binary records of the type found in /var/adm/wtmp to formatted
ASCII records. The ASCII version is useful when it is necessary to edit
bad records.
The argument -ic is used to denote that input is in ASCII form and that
output is to be written in binary form.
wtmpfix examines the standard input or named files in utmp.h 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, acctcon
faults when it encounters certain date-change records.
Each time the date is set, a pair of date change records are 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 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 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 writes a diagnostic to
the standard error. In this way, wtmpfix reduces the chance that acctcon
will fail when processing connect accounting records.
