Hi Nagiosexchange users!!! I have some problems with this bash script. The objetive is to monitor all the incorrect logins to the sistem so I created this script. check_acces ----------------------- #!/bin/bash di=`date '+%B %d'` for i in `cut -f1 -d: /etc/passwd`; do kkY=`grep \Failed\ \keyboard-interactive/pam\ \for\ \$i /var/log/messages |cut -c1-15|awk "/$di/"` if [ "$kkY" != "" ] then sa1="$sa1 User: $i Date of Attempts:$kkY" fi done kk6=`grep \Failed\ \keyboard-interactive/pam\ \for\ \illegal\ \user /var/log/messages |cut -c1-15 |awk "/$di/"` sal2="EXISTING USERS:$sa1 NO EXISTING USERS: Date of Attempts:$kk6" sal3=`echo $sal2` echo $sal3 The script works fine on shell, I execute the script like this ./check_acces and it returns this EXISTING USERS: User: root Date of Attempts:May 31 08:40:03 May 31 08:40:04 May 31 08:40:15 May 31 08:40:17 May 31 08:40:18 User: jon Date of Attempts:May 31 08:40:33 May 31 08:40:34 May 31 08:40:35 May 31 08:40:36 May 31 08:40:38 NO EXISTING USERS: Date of Attempts:May 31 08:40:54 May 31 08:40:56 May 31 08:40:57 May 31 08:40:59 May 31 08:41:01 May 31 08:41:02 May 31 08:41:04 May 31 08:41:14 May 31 08:41:15 May 31 08:41:16 May 31 08:41:17 May 31 08:41:19 May 31 08:41:20 May 31 08:41:23 this is ok, it works fine. But when I declare a service and a command on Nagios with this script something extrange happends, only appears this on Nagios, where are the incorect logins? They doesn´t appear. <table width=100%> <tr> <td width=11%> <div align=center><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=1&sortoption=1"></a><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=2&sortoption=1"></a></div> <td width=13%> <div align=center> <a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=1&sortoption=2"></a><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=2&sortoption=2"></a></div> <td width=13%> <div align=center> <a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=1&sortoption=3"></a><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=2&sortoption=3"></a></div> <td width=17%> <div align=center> <a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=1&sortoption=4"></a><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=2&sortoption=4"></a></div> <td width=14%> <div align=center> <a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=1&sortoption=6"></a><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=2&sortoption=6"></a></div> <td width=14%> <div align=center><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=1&sortoption=5"></a><a href="http://vctsnag/nagios/cgi-bin/status.cgi?hostgroup=test&style=detail&sorttype=2&sortoption=5"></a></div> <td width=14%> <div align=center></div></table> Service Status Last Check Duration Attempt Status information <table width=100%> <tr> <td width=16%> <table width=100%> <tr> <td width=87%>Incorrect Access <table width=100%> <tr> <td width=100%><a href="http://vctsnag/nagios/cgi-bin/extinfo.cgi?type=2&host=localhost&service=Accesos+incorrectos"></a></table> <td width=12%> <div align=right> <table width=100%> <tr> <td width=100%></table></div> </table> <td width=3%>OK <td width=16%>05-31-2007 09:30:46 <td width=12%>2d 23h 30m 55s <td width=2%>1/4 <td width=48%>EXISTING USERS: NO EXISTING USERS: Date of Attempts: </table> I dont know why when the script is executed by nagios it doesn´t return anything and it works fine on shell.
