For simplicity right now I am just trying to use check_ping.<o:p></o:p> <o:p> </o:p> I have written an expect script (lhm.sh) that logs into the VPN and then runs a check_ping command. Here is the code for lhm.sh:<o:p></o:p> 1 #!/usr/bin/expect -f<o:p></o:p> 2 set cmd_one [lindex $argv 0];<o:p></o:p> 3 log_user 0<o:p></o:p> 4 spawn vpnclient connect lhm pwd password<o:p></o:p> 5 expect "(y/n): " {send "y\r"}<o:p></o:p> 6 spawn ./check_ping -H $cmd_one -w 3000.0,80% -c 5000.0,100% -p 3<o:p></o:p> 7 interact<o:p></o:p> 8 set status [wait]<o:p></o:p> 9 #puts [lindex $status 3]<o:p></o:p> 10 exit [lindex $status 3]<o:p></o:p> <o:p> </o:p> Line #3 – disables the output to go to stdout. This hides all of the nasty long VPN connection information.<o:p></o:p> Line #4 – connects to the VPN<o:p></o:p> Line #5 – sends a ‘y’ so the VPN is connected<o:p></o:p> Line #8 – gets the exit return code<o:p></o:p> Line #10 – exits with the exit return code from $status.<o:p></o:p> <o:p> </o:p> When I call ‘./lhm.sh 10.30.31.51’ this is the output:<o:p></o:p> [root@monitor plugins]# ./lhm.sh 10.30.31.51<o:p></o:p> PING OK - Packet loss = 0%, RTA = 60.68 ms<o:p></o:p> [root@monitor plugins]#<o:p></o:p> <o:p> </o:p> When I call ‘./lhm.sh 10.30.31.51’ with the puts un-commented this is the output:<o:p></o:p> [root@monitor plugins]# ./lhm.sh 10.30.31.51<o:p></o:p> PING OK - Packet loss = 0%, RTA = 71.03 ms<o:p></o:p> 0<o:p></o:p> [root@monitor plugins]#<o:p></o:p> <o:p> </o:p> When I call ‘./lhm.sh 10.30.31.61’ (A WRONG IP) with the puts un-commented this is the output:<o:p></o:p> [root@monitor plugins]# ./lhm.sh 10.30.31.61<o:p></o:p> CRITICAL - Plugin timed out after 18 seconds<o:p></o:p> 2<o:p></o:p> [root@monitor plugins]#<o:p></o:p> <o:p> </o:p> The problem is, when I create a custom check command in /etc/Nagios/checkcommands.cfg to call /usr/lib/Nagios/plugins/lhm.sh Nagios always reports it as up and (No output!). It even reports at UP if I give it a wrong IP (10.30.31.61).<o:p></o:p> Host Status: UP <o:p></o:p> Status Information:(No output!)<o:p></o:p> <o:p> </o:p> Any ideas?<o:p></o:p> <o:p> </o:p> <o:p> </o:p> Thanks!<o:p></o:p> <div> Danny Russell<o:p></o:p> Mobile Productivity, Inc.<o:p></o:p> <a href="mailto:drussell@mpifix.com" title="mailto:drussell@mpifix.com">drussell@mpifix.com</a><o:p></o:p> work-801.437.5885 mbl-801.722.5837<o:p></o:p> Enabling the World To Work<o:p></o:p> </div> <o:p> </o:p> </div> </body> </html>
