Synchronet v3.19b-Win32 (install) has been released (Jan-2022).

You can donate to the Synchronet project using PayPal.


The Synchronet Configuration Utility (SCFG) is used for viewing and modifying the various CNF files in the Synchronet ctrl directory.

SCFG Main Menu


SCFG may be invoked from the Synchronet Control Panel with the BBS->Configure menu option:

Or by running scfg from a command prompt.

:!: Note: If the Synchronet exec directory is not in your search path, you may need to change the current working directory (e.g. using cd) or specify the full path to scfg.


SCFG is a native executable program.

On Windows, the executable file is: exec/scfg.exe

On Unix, the executable file is: exec/scfg

Command-line Usage

Help on the command-line usage can be displayed by executing the command: scfg -? or scfg –help:

CTRL Directory

If the SBBSCTRL environment variable is set, then SCFG will find the CNF files without needing you to specify the path to the ctrl directory ([ctrl_dir]) on the command-line.

If the SBBSCTRL environment variable is not set and the [ctrl_dir] is not specified on the command-line, SCFG will look for the CNF files in the current working directory.

Usage and Help

At any time within SCFG, you can press the F1 key or click the ? on a window to get online help about the section being edited.

  • Up and Down arrows: Move the lightbar that highlights the desired item.
  • Home: highlight first option in the menu.
  • End: highlight the last option in the menu.
  • Enter: select the highlighted item.
  • Esc return to the previous menu, or if at the top-level menu, quit the SCFG application.
  • Pressing the first letter or number of an item in the menu will highlight that item.
