This is an external module. Please note that it may or may not work with the current release (1.9.1). This module is not included in the default ZNC installation, and you will need to manually compile it before you can load this module. Contact the author if you have any questions, but feel free to ask in #znc on Libera.Chat. Someone might be able to help you there. |
The `CService` ZNC module provides secure login functionality for X on UnderNet, including support for 2FA/TOTP authentication and LoC (Login on Connect). It allows users to configure login details, enable/disable 2FA, and specify user modes. Sensitive data, such as passwords and 2FA secrets, are encrypted using AES-256 encryption for enhanced security.
Getting the Code
The code for this module can be found here.
Compatibility
This module was compiled and tested with ZNC 1.10.
Features
- Secure Login: Authenticate with UnderNet using your username, password, and optional 2FA/TOTP.
- 2FA/TOTP Support: Enhance security by adding time-based one-time passwords.
- LoC (Login on Connect): Log in to UnderNet automatically using the LoC feature.
- Custom User Modes: Set user mode prefixes (-x!, +x!, or -!+x) during server connection.
- Encrypted Credentials: Passwords and 2FA secrets are stored securely using AES-256 encryption.
Usage
Arguments
This user module takes none arguments. No additional arguments are required to load the module. Use commands to configure settings.
Read loading modules to learn more about loading modules.
Commands
setusername
Sets the UnderNet username:
/msg *cservice setusername your_username
unsetusername
Removes the stored UnderNet username:
/msg *cservice unsetusername
setpassword
Sets the UnderNet password. The password is stored securely using AES-256 encryption:
/msg *cservice setpassword your_password
unsetpassword
Removes the stored UnderNet password:
/msg *cservice unsetpassword
setsecret
Sets the 2FA/TOTP secret key. The secret is stored securely using AES-256 encryption:
/msg *cservice setsecret your_2fa_secret
enable2fa
Enables 2FA/TOTP for secure logins:
/msg *cservice enable2fa
disable2fa
Disables 2FA/TOTP:
/msg *cservice disable2fa
setusermode
Sets the user mode prefix for the server connection. Valid options are -x!, +x!, -!+x, or an empty string:
/msg *cservice setusermode +x!
showconfig
Displays the current configuration settings:
/msg *cservice showconfig
Example Usage
1. Set your username:
/msg *cservice setusername MyUser
2. Set your password:
/msg *cservice setpassword MyPassword
3. Set your TOTP secret:
/msg *cservice setsecret ABCDEFGHIJKLMNOPQRSTUV
4. Enable 2FA:
/msg *cservice enable2fa
5. View your current configuration:
/msg *cservice showconfig
Formatting the 2FA Secret Key
The CService website provides the 2FA secret key in eight groups separated by spaces, like this:
a1b2 c3d4 e5f6 g7h8 i9j0 k1l2 m3n4 o5p6
Before entering the key into the module, you must: 1. Remove all spaces. 2. Convert all lowercase letters to uppercase.
For example, if CService gives you `a1b2 c3d4 e5f6 g7h8 i9j0 k1l2 m3n4 o5p6`, you should enter it as:
A1B2C3D4E5F6G7H8I9J0K1L2M3N4O5P6
This ensures compatibility with the module.
You can use the following Linux command to reformat the key automatically:
echo "a1b2 c3d4 e5f6 g7h8 i9j0 k1l2 m3n4 o5p6" | tr -d ' ' | tr '[:lower:]' '[:upper:]'
Notes
- Always generate a secure encryption key (`MASTER_KEY`) before compiling the module. Use the following OpenSSL command:
openssl rand -hex 32 Replace `MASTER_KEY` in the source code with the generated key.
- The `MASTER_KEY` must be kept safe. If lost, the encrypted password and 2FA secret key will no longer work and you'll have to reconfigure it.
- For changes to take effect, reload the module:
/znc unloadmod cservice /znc loadmod cservice
