NGTeco Time Clocks

The ecwifi.txt file is a configuration template used by (like the W2, W3, and K4 models) to manually set up Wi-Fi via a USB drive.

ecuser.txt

While ecwifi.txt handles network settings, a similar file called is often used in the same ecosystem. While ecwifi.txt configures the hardware's connection, ecuser.txt acts as a template for bulk-enrolling employee names, IDs, and passwords via USB, allowing administrators to manage staff lists in a spreadsheet-like format on a PC before syncing them to the clock.

System Information : Basic device fingerprinting – model, firmware version, and uptime. This helps identify if the file belongs to the correct device during a bulk restore.
Radio Stats : Current channel, transmit power, and client count per radio. This is invaluable for real-time interference debugging.
WLAN Configuration : The names (SSIDs), security settings, and associated VLANs. Note: Passwords are typically hashed or omitted for security.
Error Logs : A short buffer of the last few hardware-level errors or reboots. A persistent "Watchdog timeout" often points to a faulty EC.
Ethernet/Port Status : Since most APs are powered over Ethernet (PoE), this section can tell you if the AP is underpowered.

Information Disclosure: Although passwords are hidden, SSIDs, VLAN IDs, IP addresses, and MAC addresses are usually in plain text. An attacker gaining access to this file can map your network topology.
Default Locations: If your AP has a misconfigured TFTP server or a public SMB share, an attacker could request http://<ap-ip>/ecwifi.txt or tftp://<ap-ip>/ecwifi.txt and download it without authentication.
Log Rotation: On busy APs, ecwifi.txt can grow large and be inadvertently included in public bug reports or forums. Always sanitize the file (remove MACs and IPs) before sharing.

Line Endings:

Ensure the file uses Unix-style (LF) line endings rather than Windows (CRLF). NGTeco Time Clocks The ecwifi
