Hi Simon, Let Nagios to write the action into a file. This is because you should be sure that Nagios runs the command exactly as yours. There can be some exceptions (bugs, some missed escape chars, ...). Thus, see the difference. First of all, let it write into a file. For instance, change the command like, echo '/usr/bin/printf "%b" "Svc:$SERVICEDESC$ ++Host:$HOSTALIAS$ ++ Addr:$HOSTADDRESS$ ++ State:$SERVICESTATE$ ++Date:$SHORTDATETIME$" | /usr/local/bin/gammu --sendsms TEXT $CONTACTPAGER$' >> /tmp/someTempFile After you're sure a notification is done, open that temporary file and get a random line (first, last or any) then try to execute it. Result? Same? This makes difference. Waiting for your reply.

The nagios.log reports that the notification has been sent sucessfully but the message is never received, if I run the command manually the sms is received. Any ideas?
