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 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.
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, acctcon(1M) will
fault when it encounters certain date-change records.
Each time the date is set, a pair of date change records are
written to /etc/wtmp. The first record is the old date
denoted by the string old time placed in the line field and
the flag OLDTIME 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 NEWTIME 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(1) will fail when processing connect accounting
