NAME    [Toc]    [Back]

     acctcon, acctcon1,	acctcon2 - connect-time	accounting

SYNOPSIS    [Toc]    [Back]

     /usr/lib/acct/acctcon [options]
     /usr/lib/acct/acctcon1 [options]
     /usr/lib/acct/acctcon2

DESCRIPTION    [Toc]    [Back]

     acctcon converts a	sequence of login/logoff records to total accounting
     records (see the tacct format in acct(4)).	 Login/logoff records are read
     from standard input.  The file /var/adm/wtmp is usually the source	of the
     login/logoff records; however, because it may contain corrupted records
     or	system date changes, it	should first be	fixed using wtmpfix.  The
     fixed version of file /var/adm/wtmp can then be redirected	to acctcon.
     The tacct records are written to standard output.	Here are the options
     for acctcon:

     -l	file   file 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(1M)
	       and utmp(4).

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

     acctcon is	a combination of the programs acctcon1 and acctcon2.  acctcon1
     converts login/logoff records, taken from the fixed /var/adm/wtmp 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 above, as well as with the following	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 noncurrent files.

     acctcon1 and acctcon check	the environment	variable ACCT_A_TSIZE to
     figure out	the maximum number of login lines that it might	need to
     report.  acctcon checks the environment variable ACCT_A_USIZE to figure
     out the maximum number of distinct	login names it might need to report.

EXAMPLES    [Toc]    [Back]

     The acctcon command is typically used as follows:

	  acctcon -l lineuse -o	reboots	< tmpwtmp > ctacct

     The acctcon1 and acctcon2 commands	are typically used as follows:

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

NOTICES    [Toc]    [Back]

     The line-usage report is confused by date changes.	 Use wtmpfix (see
     fwtmp(1M)), with the /var/adm/wtmp	file as	an argument, to	correct	this
     situation.
