ACCTCON(8) Maintenance Procedures ACCTCON(8)

NAME

acctcon, acctcon1, acctcon2 - connect-time accounting

SYNOPSIS

/usr/lib/acct/acctcon [-l lineuse] [-o reboot]


/usr/lib/acct/acctcon1 [-p] [-t] [-l lineuse] [-o reboot]


/usr/lib/acct/acctcon2

DESCRIPTION

acctcon converts a sequence of login/logoff records to total accounting
records (see the tacct format in acct.h(3HEAD)). The login/logoff records
are read from standard input. The file /var/adm/wtmpx is usually the
source of the login/logoff records; however, because it might contain
corrupted records or system date changes, it should first be fixed using
wtmpfix. The fixed version of file /var/adm/wtmpx can then be redirected
to acctcon. The tacct records are written to standard output.


acctcon is a combination of the programs acctcon1 and acctcon2. acctcon1
converts login/logoff records, taken from the fixed /var/adm/wtmpx file,
to ASCII output. acctcon2 reads the ASCII records produced by acctcon1
and converts them to tacct records. acctcon1 can be used with the -l and
-o options, described below, as well as with the -p and -t options.

OPTIONS

-p
Print input only, showing line name, login name, and time
(in both numeric and date/time formats).


-t
acctcon1 maintains a list of lines on which users are
logged in. When it reaches the end of its input, it emits a
session record for each line that still appears to be
active. It normally assumes that its input is a current
file, so that it uses the current time as the ending time
for each session still in progress. The -t flag causes it
to use, instead, the last time found in its input, thus
assuring reasonable and repeatable numbers for non-current
files.


-l lineuse
lineuse is created to contain a summary of line usage
showing line name, number of minutes used, percentage of
total elapsed time used, number of sessions charged, number
of logins, and number of logoffs. This file helps track
line usage, identify bad lines, and find software and
hardware oddities. Hangup, termination of login(1) and
termination of the login shell each generate logoff
records, so that the number of logoffs is often three to
four times the number of sessions. See init(8) and
utmpx(5).


-o reboot
reboot is filled with an overall record for the accounting
period, giving starting time, ending time, number of
reboots, and number of date changes.

EXAMPLES

Example 1: Using the acctcon command.

The acctcon command is typically used as follows:


example% acctcon -l lineuse -o reboots < tmpwtmp > ctacct


The acctcon1 and acctcon2 commands are typically used as follows:


example% acctcon1 -l lineuse -o reboots < tmpwtmp | sort +1n +2 > ctmp
example% acctcon2 < ctmp > ctacct

FILES

/var/adm/wtmpx
History of user access and administration information

NOTES

The line usage report is confused by date changes. Use wtmpfix (see
fwtmp(8)), with the /var/adm/wtmpx file as an argument, to correct this
situation.


During a single invocation of any given command, the acctcon, acctcon1,
and acctcon2 commands can process a maximum of:

o 6000 distinct session

o 1000 distinct terminal lines

o 2000 distinct login names


If at some point the actual number of any one of these items exceeds the
maximum, the command will not succeed.
