1. Automated Login & Configuration Script (Python/Telnet)

If you are looking for a script to automate the configuration of a ZTE ZXDSL modem (e.g., setting up PPPoE, changing WiFi settings, or rebooting), Python with the telnetlib library is the standard method. These modems often use Telnet for backend management.

Here is a full script example to log in and execute commands: zxdl script

import telnetlib
import time
def configure_zxdsl_modem(host, username, password, commands):
    """
    Connects to a ZXDSL modem via Telnet and executes a list of commands.
    """
    try:
        # Connect to the modem
        print(f"Connecting to host...")
        tn = telnetlib.Telnet(host, timeout=10)
# Login sequence
        tn.read_until(b"Login: ", timeout=5)
        tn.write(username.encode('ascii') + b"\n")
tn.read_until(b"Password: ", timeout=5)
        tn.write(password.encode('ascii') + b"\n")
# Wait for the prompt (common ZTE prompts are # or >)
        time.sleep(2)
print("Logged in successfully. Executing commands...")
# Execute commands
        for cmd in commands:
            print(f"Executing: cmd")
            tn.write(cmd.encode('ascii') + b"\n")
            time.sleep(1) # Wait for command to process
# Exit session
        tn.write(b"exit\n")
        output = tn.read_all().decode('ascii')
        print("Configuration complete.")
        print("--- Output ---")
        print(output)
except Exception as e:
        print(f"Error: e")
# --- USAGE ---
# Default ZXDSL credentials are often admin/admin or admin/1234
modem_ip = "192.168.1.1" # Default gateway
user = "admin"
pwd = "admin"
# List of CLI commands to run (varies by firmware version)
# Examples for ZXDSL 831II:
command_list = [
    "wan show",          # Show WAN status
    "lan show",          # Show LAN status
    "reboot",            # Reboot the device (use with caution)
    # "save"             # Save configuration (if required by model)
]
if __name__ == "__main__":
    configure_zxdsl_modem(modem_ip, user, pwd, command_list)

7. Security Considerations

Credential Exposure: ZXDL scripts often contain hardcoded plaintext credentials to access the OLT. Strict access controls (chmod 700) and secret management tools (HashiCorp Vault) must be used if these scripts are stored on disk.
SN Exposure: PON Serial Numbers are sensitive. Leaked ZXDL provisioning scripts can provide attackers with the exact information needed to attempt ONT spoofing/cloning on the network.
Transport Security: ZXDL scripts should never be transmitted over unencrypted Telnet sessions in production environments. SSHv2 is mandatory.

Version Control Your Scripts

Since zxdl scripts control critical automation, store them in Git (or equivalent). Treat them as source code. resolve variant streams (low/medium/high quality)

Implement Idempotent Operations

Ensure that running the same script twice does not produce duplicate results. Check for existing output files before processing. Key Characteristics of ZXDL Scripts:

3. Jobs and Tasks

A job contains one or more tasks executed sequentially:

JOB process_invoices
  TASK extract_data
    COMMAND read_csv --file $input_path/invoices.csv
  END_TASK
  TASK transform_amounts
    COMMAND multiply --column net_total --factor 1.19
  END_TASK
END_JOB

Key Characteristics of ZXDL Scripts:

Batch Processing: Download hundreds of files from a list.
Pattern Matching: Use regex to find specific file extensions or URL structures.
Resume Capability: Automatically resume interrupted downloads.
Header Simulation: Mimic browser headers to bypass basic anti-hotlinking mechanisms.

1. Archiving Streaming Playlists (HLS/DASH)

M3U8 playlists are notoriously difficult to download with standard tools. A ZXDL script can parse the master manifest, resolve variant streams (low/medium/high quality), and download all .ts segments before merging them into an .mp4.

Example Snippet:

[downloader: hls]
type = "m3u8"
manifest_url = "https://streaming.video.com/live/abc123.m3u8"
quality = "best" ; Options: best, worst, 1080p
merge = true
output_format = "mp4"
