The Mumbling Herald

A grumpy old herald who watches your Mumble server and announces comings and goings via XMPP.

Full setup

• Create a herald user with minimal permissions

  sudo useradd -r -s /bin/false -d /var/lib/mumblingherald -m mumblingherald
  sudo usermod -a -G mumble-server mumblingherald  # if mumble-server group exists for log access
  

• Copy script to user's directory, make it executable, and set ownership

  sudo cp mumblingherald /var/lib/mumblingherald
  sudo chown mumblingherald:mumblingherald /var/lib/mumblingherald/mumblingherald
  sudo chmod 700 /var/lib/mumblingherald/mumblingherald
  

• Edit the script to configure details
  • MUMBLE_LOG_FILE: path to your Mumble server log
  • XMPP_RECIPIENTS: recipient JID for notifications
  • MONITORED_CHANNELS: display name of channels to watch
• Install go-sendxmpp
  • Download the latest binary from the go-sendxmpp releases page
  • Extract and copy to system location

    sudo cp go-sendxmpp /usr/local/bin/
    sudo chmod 755 /usr/local/bin/go-sendxmpp
    

• Create config directory

  sudo -u mumblingherald mkdir -p /var/lib/mumblingherald/.config/go-sendxmpp
  

• Create XMPP config in /var/lib/mumblingherald/.config/go-sendxmpp/config (edit values!)

  username: herald@your-xmpp-server.com
  password: your-password
  

  • Correct permissions

    chmod 600 /var/lib/mumblingherald/.config/go-sendxmpp/config
    

• Create systemd service in /etc/systemd/system/mumblingherald.service
