scum_simple_rcon_ue4ss/INSTALL.md

Install

1. Build the mod; see BUILD.md.
2. Copy the built folder into the SCUM server Win64 directory:

<ServerInstall>\SCUM\Binaries\Win64\ue4ss\Mods\scum_simple_rcon\

Expected layout:

Win64/
  dwmapi.dll
  SCUMServer.exe
  ue4ss/
    UE4SS.dll
    UE4SS-settings.ini
    Mods/
      mods.txt
      scum_simple_rcon/
        enabled.txt
        config.ini
        dlls/
          main.dll

3. Edit config.ini:

[rcon]
bind_address = 127.0.0.1
port = 27015
password = use-a-real-password

4. Enable the mod in ue4ss/Mods/mods.txt:

scum_simple_rcon : 1

5. Start the server and check ue4ss/UE4SS.log for:

[scum_simple_rcon] rcon: listening on 127.0.0.1:27015

6. Test locally:

mcrcon -H 127.0.0.1 -P 27015 -p use-a-real-password rcon.status
mcrcon -H 127.0.0.1 -P 27015 -p use-a-real-password rcon.admins
mcrcon -H 127.0.0.1 -P 27015 -p use-a-real-password rcon.dispatch
mcrcon -H 127.0.0.1 -P 27015 -p use-a-real-password rcon.chat

Security note: keep bind_address = 127.0.0.1 unless you are putting this behind a firewall/VPN. Source RCON is not encrypted.

Before sending an AdminCommand (for example SetTime, SpawnItem, or an admin-targeted SendNotification), make sure the server has:

<ServerInstall>\SCUM\Saved\Config\WindowsServer\AdminUsers.ini

with at least one 17-digit SteamID64. This mod intentionally does not fall back to the first online player.

Ordinary SendChat is different: it only needs an authenticated RCON client and a real online recipient. It does not need AdminUsers.ini, does not create a controller/channel, and refuses a targeted send when that SteamID is not currently connected.

For the no-player test, wait until the SCUM world has loaded, leave the server empty, then run rcon.dispatch followed by a harmless command such as:

mcrcon -H 127.0.0.1 -P 27015 -p use-a-real-password SetTime 12

rcon.dispatch must report synthetic=ready. If the native executor signature is not found, do not force an address: the SCUM build changed and the mod needs an updated, tested signature.
