Here is an example of how you can write a Python script to automate the deployment process for a DynDNS server:
``
python
import datetime
import socket
from hermes import Hermes # Hermet package is required to work with Hermes server
def get_hermes_url():
return "http://127.0.0.1:8000"
def deploy_dyndns(hermes_url):
try:
Hermes.connect_to(get_hermes_url())
dyndns_url = Hermes.getDynDNSUrl()
# Prepare the new DNS server name, user data and password
name = "your_dyndns_server_name"
username = "your_user_username"
password = "your_user_password"
# Deploy new DynDNS record
Hermes.recordUpdate(dyndns_url,
{'name': name, 'username': username, 'password': password},
[{'action': 'add', 'changeType': 'zone'}])
except Exception as e:
print(f"Error deploying dyn dns: {e}")
def is_not_changed(hermes_url, config_name):
try:
Hermet.getDynDNSUrl()
return False
except Exception as e:
print(f"An error occurred while checking for a change: {e}")
def main():
Hermes.connect_to(get_hermes_url()) # Connect to the DynDNS server
if is_not_changed(get_hermes_url(), 'DynDNS'):
deploy_dyndns(get_hermes_url())
config_name = datetime.datetime.now().strftime("%Y%m%d%H%M")
Hermes.command(f"recordupdate -d {config_name} http://127.0.0.1:8000 DynDNSName DynDNSServer")
# Send an update message to the receiver
Hermes.update("Telegram:+100****2525", f"DynDNS Updated - {datetime.datetime.now():%Y-%m-%d %H:%M:%S}",
"DynDNS Server updated successfully.")
if __name__ == "__main__":
main()
`
Replace "/root/.hermes/skills/cf-dyndns.sh"
with your cf-dyndns.sh
. Also, ensure to pass correct credentials and you DynDNS server details.
To run this script, simply pipe it into a for
loop using your cron job. Here's an example of how the command would look like:
`
bash
root[/usr/bin/sh]# (assuming you are running in a Linux server or desktop)
root[/usr/bin/sh]# chmod 755 cf-dyndns.sh
`
After that, enter your cf-dyndns.sh` script directly when prompted without any output for the "Deploy DynDNS" operation.
Please remember to keep hermes and python libraries up-to-date since you might need an additional Hermet package. Also remember this is just a basic example of sending and retrieving records from the dyndns server using Hermes Python library, for any task requiring more sophisticated operations consider your use case, especially if you are building anything that will interact multiple servers or dynamically update content on many sites.
