telegram_notifier

A Telegram bot that I use to send notifications from my servers to my phone. Listens TCP port 6666 on the machine for "notifications", which are (hopefully) plain text. Sends whatever it receives in a Telegram message. Callbacks can be defined to trigger code when certain commands are sent to the bot. There are a few commands right now, which are:

• /pause: Pauses all messages sent by the bot. Messages will be stored in a queue instead and will be sent when a /continue is received.
• /continue: Resumes normal operation of the bot and sends all messages waiting in the queue that were stored when the bot was paused.
• /notifyoff: Disables chat notifications. Sets the disable_notification parameter of the sendMessage method of the bot API.
• /notifyon: Reenables chat notifications. (Notifications are enabled by default)

systemd service

There is a systemd service file for the bot. See telegrambot.service. It runs the service under the user and group telegram_bot, which must be created manually.

SELinux policy

SELinux users can use this SELinux policy to confine the service. Note that the port the service binds to (6666 for now) must be labeled as telegrambot_port_t.

Requirements

• Boost
