+ | Some points in this config: | ||
+ | * **After**. If you are using syslog with sbbs, so it is nice to put that requirement before systemd tries to launch sbbs. | ||
+ | * **Type**. If you are to run SBBS in daemonized mode, the main executable will exit after the daemon is called. This could confuse systemd into thinking the process is finished. If you use " | ||
+ | * **Environment**. In order to avoid having multiple files, you can embed the variables inside the service file. | ||
+ | * **User/ | ||
+ | * **PermissionsStartOnly**. This one tells systemd to execute ExecStartPre as root, but ExecStart as the user and group declared in User, | ||
+ | * **ExecStartPre**. For some weird reason, capabilities are frequently lost from the sbbs executable. It is possible to mitigate the effect by running setcap just before the daemon is ran. The binding won't fail anymore using this. Please notice you can't point a symlink here, so modify the architecture directory to the right path (gcc.linux.x64.exe.release or gcc.linux.exe.release). | ||
+ | * **ExecStart**. If you don't want to get syslog entries duplicated you will have to run SBBS in daemonized mode, so the " | ||
+ | * **RestartSec**. It's advisable to wait some secs before attempting restarting in case of failure, just to give some time for binding release. | ||
+ | |||
+ | Installation instructions: | ||
+ | -Modify the environment variables to match your SBBS setup | ||
+ | -Modify User and Group. If you run this as root you don't need the ExecStartPre line. | ||

+ | ===== 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 '' | ||
+ | |||
+ | new-session sbbs ; | ||
+ | new-window -n sbbs tail -n 50 -f / | ||
+ | split-window -h / | ||
+ | split-window -t 1 -v / | ||
+ | set-option mouse on | ||
