The problem was due to the /dev/ttyACM0 device that was created when the mobile was connected via USB not having rw access for other user. Is there a way to make these permissions persistent on a reboot or disconnection of a hot plug device?

Otherwise, I don't have anything sensible in my mind about this. Could you check (if possible pass to Nagios user and try to execute) /usr/bin/printf /usr/local/bin/gammu can be readable and executable by Nagios user? you can simply add # chmod +x /usr/bin/printf # chmod +x /usr/local/bin/gammu however, one more problem can occur. gammu also could be able to read its resources as nagios user. Anyway, let's try to execute the command as Nagios user. Waiting for your reply...

Again if I run the output of the text file manually then the sms is sent as expected but not as part of the notification command. Could it be due to permissions? /usr/bin/printf "%b" "Svc:HTTP ++Host:Abs Self Service Server 2 ++ Addr:<a href="http://89.50.35.113" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">89.50.35.113</a> ++ State:CRITICAL ++Date:23-03-2007 11:53:08" | /usr/local/bin/gammu --sendsms TEXT 00000000 Regards Simon<div> <div>On 3/18/07, Dinçer Kavraal <<a href="mailto:dkavraal@yahoo.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> dkavraal@yahoo.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> 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.
