LOCK file in the spooler: The smsd inherits it's priviledges from the user who started the daemon. If starting is done by the root or system startup, priviledges of root are inherited.

If the smsd is started by the unpriviledged user, account switching is not available. Easiest way to run the smsd is running it as a root: Method 1 recommended for the normal use: On some installations Debian, Ubuntu for example script is using name smstools.

With sms3 script you can ensure that: If smsd is already running, duplicate daemon is not started. When smsd is stopped while it is sending a multipart message, the script will wait until all parts are sent. Information of the process is printed to terminal, so you can see why the daemon is not stopped immediately.

In case of troubles there is force-stop argument available. This handles all smsd processes, not just the main process. When the smsd main process receives a termination signal, it sends it to all subprocesses. After a signal is received, no more new jobs are started.

Already started jobs are completed, which usually will not take too much time. The smsd will run in foreground and status monitor is printed to terminal. Press Ctrl-C to stop the program.

There are two ways to do this: Define user account settings in sms3 script and use it to start the smsd by the root. Start the smsd by the unpriviledged user. In both cases you must ensure that infofile and pidfile are writable by the unpriviledged user.

Location and name of those files can be defined in the config file, if sms3 script is not used. Most recommended way is using the sms3 script, and change settings in this script.

Selected user must have write permissions to the device s. Selected user must also have write permissions to the spool directories. For example those directories can be owned by this user.

Other users who are permitted to send messages should have write permissions to the outgoing directory. If there are any problems, they are reported and smsd shuts down.

This prevents problems in the future, for example when smsd was run for couple of days and failed directory is first time needed. If a directory is not accessible, smsd stops. This program or script is executed at a given interval while the smsd is running.

In the future versions there will also be some return value handling. Currently return values other than zero are reported to the log file. This example is about verifying the delivery of a sent message.

If it's not delivered fast enough, a same message is sent to the alternate phone number. When the first message is sent:The recent upgrade to Ubuntu Precise Pangolin left me somewhat hanging when it comes to creating launchers on the desktop, and also in the Unity Launcher (also called quicklaunch in some places) for Zend Studio and PHPStorm.
