Electronics & Automation

Wiremod is arguably the most complex and powerful addon in the Garry’s Mod ecosystem. It allows players to build functioning computers, automated turrets, and intricate navigation systems. However, its “Expression 2” (E2) system can be misused to cause significant server lag or crashes if not properly restricted.

​
1. Installation

  1. Add the Wiremod addon to your server’s Workshop Collection.
  2. Restart the server.
  3. Verify installation by checking the “Wire” tab in your spawn menu (Q Menu).

​
2. Essential Stability Settings

To prevent players from running malicious E2 scripts that loop infinitely and freeze the server CPU:
  1. In-game, open your Spawn Menu (Q).
  2. Navigate to Utilities > Wire > Expression 2.
  3. CPU Quotas: Set Soft Quota to 2000 and Hard Quota to 8000.
    • Result: If a player’s chip exceeds these values, the server automatically disables it.
  4. Extensions: Ensure the http and console extensions are Disabled to prevent outbound DDoS attempts and console spam.

​
3. Group Restrictions

If you find that regular players are still causing issues, we recommend restricting the “Expression 2” tool to reliable groups (VIP/Admin) using ULX:
  1. Open !menu.
  2. Go to Cmds > Sandbox > Tool Restrictions.
  3. Select wire_expression2 and restrict it to supporter or higher.
