Start, Control, and Monitor Synchronet BBS using systemd

If you run a modern GNU/Linux distribution, it is likely using systemd as its “init system” for starting and controlling system services/daemons. Installing Synchronet into systemd is recommended for such systems so that Synchronet will start upon system boot and provide all the control and monitoring expected of an integrated system service.

Install

If you've installed Synchronet, you should already have the required system service unit file in the following location:

sbbs/repo/install/systemd/sbbs.service

Read this file for the current instructions on how to install and configure it, but here's a summary for quick reference:

  1. Copy or symlink the sbbs.service file to the correct directory, e.g. for Debian/Ubuntu Linux, that would be: /lib/systemd/system
  2. Enable the BBS service by running: sudo systemctl enable sbbs
  3. To run the BBS service without rebooting, run: sudo systemctl start sbbs

Any necessary edits should be made using sudo systemctl edit sbbs, thus creating the file:

/etc/systemd/system/sbbs.service.d/override.conf

This will allow you to integrate any future upstream changes to the sbbs.service file without losing your local changes.

After editing the sbbs.service or overrride.conf file, execute the following command to tell systemd to reload the unit files:

sudo systemctl daemon-reload

To allow core file generation (for crash/segfault debugging), add to the [Service] section of your service unit file:

LimitCORE=infinity

Where is My Service File?

If you are already running Synchronet from systemd but can't remember where the config file is, the following commands will help.

systemctl show -p FragmentPath sbbs

Control

To start the Synchronet service

systemctl start sbbs

To restart (stop and then start) the Synchronet service

systemctl restart sbbs

To stop the Synchronet service

systemctl stop sbbs

Monitor

Display the current Synchronet service status:

systemctl status sbbs

Watch the current Synchronet service status in real-time:

watch systemctl status sbbs

Read/search the log output of the Synchronet service:

journalctl -u sbbs

Watch the log output of the Synchronet service in real-time:

journalctl -f -u sbbs

Monitoring with Byobu (Tmux backend)

You can have a text mode dashboard for monitoring and configuring your BBS realtime by using Byobu with Tmux or GNU Screen backends. If you are using the Tmux backend. The following configuration splits your screen in three panes: one for SBBS log, other for UMONITOR and a last one for SCFG. Please note that this configuration assumes SBBSCTRL variable is set and that access permissions to the needed files are set for the current user.

Create the file $BYOBU_CONFIG_DIR/windows.tmux.sbbs with the following contents:

new-session sbbs ;
new-window -n sbbs tail -n 50 -f /var/log/sbbs.log ;
split-window -h /sbbs/exec/umonitor ;
split-window -t 1 -v /sbbs/exec/scfg ;
set-option mouse on

And then run: user@localhost:~$ BYOBU_WINDOWS=sbbs byobu

If you want this to be your default environment when you log at your Synchronet server, then write the configuration to the $BYOBU_CONFIG_DIR/windows.tmux file instead of $BYOBU_CONFIG_DIR/windows.tmux.sbbs

The following screenshot shows the result:

If are using also binkd for FidoNet, this configuration will split the dashboard in 4 panes:

new-session sbbs ;
new-window -n sbbs tail -n 50 -f /var/log/sbbs.log ;
split-window -p 50 -h /sbbs/exec/umonitor ;
split-window -t 0 -p 20 -v tail -f /var/log/binkd.log ;
split-window -t 1 -v /sbbs/exec/scfg ;
set-option mouse on

Debian (alternative using tmux)

You can use Tmux to still the Synchronet BBS console running on a screen that can be attached when you need

/etc/default/sbbs

SBBSCTRL=/sbbs/ctrl

/etc/systemd/system/sbbs.service

[Unit]
Description=Synchronet BBS

Using tmux, Synchronet start in a session (called sbbs), you can attach to the running console using tmux attach -t sbbs
