To provide a detailed response to this task, we will first need to identify and replace the specific URLs or text within those URLs that contain changes in DynDNS status using a script provided by Hermes (the cloud service provider).
Please find the relevant Python scripts here:
``
#!/usr/bin/env python3
import sys
from datetime import datetime
# Define DynDNS base URL, username for user settings and public address
dynurl = "http://192.168.1.100/DNSUpdate"
username = "your_username"
public_address = "your_public_address"
status_code = []
last_update_time = None
# Connect to DynDNS server
def connect_to_dyn_server():
global status_code, last_update_time
try:
resp = requests.get(dynurl)
if resp.status_code == 200:
return True
else:
print(f"Failed to get DynDNS response code: {resp.status_code}")
return False
# Process all responses at once for efficiency
urls = ["http://dyn1.dmdns.info/DNSUpdate"],
[f"http://www DynDNS.com/{public_address}/update" ]
resp_content = None
for url in urls:
resp_content += resp.text
status_code.append(resp.status_code)
except requests.RequestException as e:
print(f"There was an error connecting to DynDNS: {e}")
`
Please replace "your_username" and the public address with your actual credentials.
Now, here's how you need to execute it.
`
bash
#!/bin/bash
# Run this script for dynamic DNS changes (no reply)
cf-dyndns.sh 2>&1 | grep -i "STATUS:NO_CHANGE"
`
This script would output:
`
DynDNS Status: NOCHANGE
`
Only if there were no changes, and it's not a cron job.

Next Step:
After identifying the target URLs for DynDNS status updates with the corresponding commands to check the DNS update process, you could write a Python script to fetch current results and compare them with previous data. This way, when a successful update is detected or an "error" is reported by Hermes/DynDNS server.
Here's an example that runs the python script in sequence to get updated lists, then to update your local DynDNS servers if necessary - you can do that as well:
`
python
#!/usr/bin/env python3
import sys
import datetime
from datetime import timedelta
dyn_url = "http://192.168.1.100/DNSUpdate"
# username and public address used to run the DynDNS server, replacing 'your_username' with your actual credentials
username = "your_username"
public_address = "your_public_address"
def get_update_status(url):
try:
return requests.get(url).status_code
def check_for_errors(previous_state, current_state):
if (current_state == 'NOCHANGE') and (previous_state == 'ERROR'):
print('DynDNS Error:', previous_state)
elif current_state != None: # Check for last successful update
current_status = get_update_status(dyn_url)
print(f'Current DynDNS Status: {get_update_status(dyn_url)}')
if(current_status!=200):
print("Update Failed. Please check the server status.")
update_needed = False
if current_state == None or (previous_state != None and previous_state == 'NOCHANGE'):
for url in ["http://dyn1.dmdns.info/DNSUpdate", "http://www DynDNS.com/{public_address}/update"]
for url in urls:
resp_content += resp.text
# Process all responses at once for efficiency
status_code.append(resp.status_code)
else:
update_needed = current_state != 'OK:'
if (not update_needed or previous_state == None) and current_state == 'ERROR':
print('DynDNS Error:', previous_state)
elif previous_status and previous_status != current_state:
# Update the local DynDNS servers
if update_needed:
if previous_status in ['NOCHANGE', 'SUCCESS']:
sys.stdout.write("Update successfully. Please check your DynDNS servers to reflect updates.\n")
else:
sys.stdout.write(f"Upgrade required after {previous_state} DynDNS error: {previous_status}.\n")
else:
print('DynDNS updated correctly')
``
Finally, execute it like above with any target URLs including private channels if they exist. If a new update is successful without prompting an update for the server to follow your command.
