Check

[Anthony BRODARD]

Hi list,

I would to detect if any user is directly connected (console) on my Linux
servers (Debian, CentOS).
I've created this bash simply bash script :

#!/bin/bash

WHO=`which who`
GREP=`which grep`
WC=`which wc`

RESULT=`$WHO | $GREP tty | $WC -l`

if [ $RESULT -ne 0 ]
then
  echo $RESULT "utilisateur(s) connecte(s) en console"
  exit 1
else
  echo "OK"
  exit 0
fi

It works fine, but I prefer to use an other method, most lighter than the
check_by_ssh.
Do you know an other way to do that, via SNMP for exemple.

Regards
