SMSGateway

This project is in Beta stage, so documentation is quite limited. Pull requests welcome!

The following instructions apply to a Raspberry PI running Ubuntu, but it should work similarly on other Linux distributions and platforms. Some commands might require to be invoked with sudo.

See SMSGateway-Android for an Android client.

SMS Tools

Install smstools:

apt install smstools

Edit /etc/smsd.conf, see Confiuration/smsd.conf for an example configuration. It uses to user smsd for the sms spooler at /var/spool/sms.

Configuration

pip install smsgateway

Copy smsgateway/config.example.py to /home/smsd/.config/smsgateway/config.py and adapt it.

Handle incoming SMS

To handling incoming sms Scripts/smshandler needs to be copied to the eventhandler specified in smsd.conf. In the example it points to /usr/local/bin/smshandler.

Make sure to make it executable (chmod +x).

Logging

mkdir /var/log/smsgateway/ && chown -R smsd:smsd /var/log/smsgateway/

Permission to control systemctl, shutdown, etc.

Copy Configuration/010_smsd-nopasswd to /etc/sudoers.d/

Make sure that the file is correct, otherwise you might lock yourself out! If you're unsure, run visudo -f /etc/sudoers.d/010_smsd-nopasswd, enter the contents in the editor and save it.

Tweaks and optimizations

Ramdisk for SMS

When lots of SMS are processed it can wear out SD cards (I destroyed one after several months). A workaround is to store the SMS messages in a ramdisk. The following is an entry in the fstab:

tmpfs   /var/spool/sms  tmpfs         nodev,nosuid,size=64M     0       0

To mount it simply call mount /var/spool/sms.

The downside is, that when the device restarts/crashed, currently processed SMS messages are lost. To work around that there are two scripts for saving&restoring the messages in Scripts/ and a oneshot-service, which can be enabled to restore the message when the device is starting.
