if my guess is right, you are looking for a way to
log off idle users? right

you could write a script to log off idle users

here is a korn shell script that could log off users that is idle for more than 60minutes or 1 hour, this script log off idle user apart from root users and users log on to the console

#!/usr/bin/ksh


who -u | sed -e "s/\./0/" -e "s/://g" |awk '$6 > 60 {print $1" "$2" "$7}' | \
while read -r NAME TER PID



do

if [ "$NAME" = "root" ]
then
echo " Idle root users can not be log off " >/dev/null
else


if [ "$TER" = "console" ]
then
echo "user logged in at the console can not be log off " >/dev/null
else

kill -9 $PID

fi
fi
done

NAME
ftpusers - list of users that may not log in via the FTP daemon DESCRIPTION
The text file ftpusers contains a list of users that may not log in using the File Transfer Protocol (FTP) server daemon. This file is used not merely for system administration purposes but for improving security within a TCP/IP networked environment. It will typically contain a list of the users that either have no business using ftp or have too many privileges to be allowed to log in through the FTP server daemon. Such users usually include root, daemon, bin, uucp, and news. If your FTP server daemon doesn't use ftpusers then it is suggested that you read its documentation to find out how to block access for certain users. Washington University FTP server Daemon (wuftpd) and Professional FTP Daemon (proftpd) are known to make use of ftpusers. Format The format of ftpusers is very simple. There is one account name (or username) per line. Lines starting with a # are ignored. FILES
/etc/ftpusers SEE ALSO
passwd(5), proftpd(8), wuftpd(8) COLOPHON
