Ubuntu – Nagios SMS notification with gammu smsd does not work

nagiossmsUbuntu

gammu-smsd configuration:

#vi /etc/gammu-smsdrc

 # Configuration file for Gammu SMS Daemon

 # Gammu library configuration, see gammurc(5)
[gammu]
 # Please configure this!
port = /dev/rfcomm0
connection = bluephonet
 # Debugging
logformat = textall

 # SMSD configuration, see gammu-smsdrc(5)
[smsd]
service = files
 #logfile = syslog
logfile = /var/log/gammu-smsd

 # Increase for debugging information
debuglevel = 0

 # Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/

It works and I can send SMS from terminal.

Best Answer

It works and I can send SMS from terminal.

Have you tested as root?

output=Error opening device, it doesn't exist.

Make sure that nagios (and apache if you want) has write permission on /dev/rfcomm0.

Check this first:

# ls -l /dev/rfcomm0

Assumming you get:

crw-rw---- 1 root dialout 216, 0 2012-08-10 23:15 /dev/rfcomm0

then add the nagios user to the dialout group:

$ sudo usermod -a -G dialout nagios

and try again.

UPDATE Mon Aug 13 17:57:59 ICT 2012

Set the SUID bit on the command to allow nagios execute gammu on behalf of the root:

# chmod 4755 /usr/bin/gammu

and try again:

# su - nagios -s /bin/bash
$ echo "test" | gammu –sendsms TEXT 0123456789
