title: Waiting For Caller (WFC)

## The Waiting For Caller (WFC) Module
The `wfc.js` module provides a Waiting For Caller (WFC) type dashboard from a bygone era. Many traditional features are available including newer concepts for modern times. Node spy is left out as it feels like something that should be left in the past.

## Accessing the WFC
By default, the WFC may be accessed via the `!WFC` main menu command when connected over a secure connection via a user with the proper [ACS](../configuration/acs.md). This can be configured as per any other menu in the system. Note that ENiGMA½ does not expose the WFC as a standalone application as this would be much less flexible. To connect locally, simply use your favorite terminal or for example: `ssh -l yourname localhost 8889`. See **Security** below for more information.

## Security
The system allows any user with the proper security to access the WFC / system operator functionality. The security policy is enforced by ACS with the default of `SCAF2ID1GM[wfc]`, meaning the following are true:

1. Securely Connected (such as SSH or Secure WebSocket, but not Telnet)
2. [Auth Factor 2+](modding/user-2fa-otp-config.md). That is, the user has 2FA enabled.
3. User ID of 1 (root/admin)
4. The user belongs to the `wfc` group.

:information_source: Due to the above, the WFC screen is **disabled** by default as at a minimum, you'll need to add your user to the `wfc` group.

To change the ACS required, specify a alternative `acs` in the `config` block. For example:
```hjson
mainMenuWaitingForCaller: {
    config: {
        // initial +op over secure connection only
        acs: SCID1GM[sysops]
    }
}
```

:information_source: ENiGMA½ will enforce ACS of at least `SC` (secure connection)

The following MCI codes are available:
* `VM1`: Node status list with the following format items available:
    * `text`: Username or `*Pre Auth*`.
    * `action`: Current action/menu.
    * `timeOn`: How long the node has been connected.
* `VM2`: Quick log with the following format keys available:
    * `timestamp`: Log entry timestamp in `quickLogTimestampFormat` format.
    * `level`: Log entry level from Bunyan.
    * `levelIndicator`: Level indicators can be overridden with the `quickLogLevelIndicators` key (see defaults below)
    * `quickLogLevelIndicators`: A **map** defaulting to the following`:
