To run the provided
cf-dyndns.sh script, you'll need to have a few prerequisites and environment set up. I'm assuming you are working on an Arch Linux system with Heroku Enterprise setup.
### Initial Setup:
1. **Update your system:**
``
bash
sudo apt update
`
2. **Configure your server (for cf-dyndns.sh
):**
You will need to set up a DynDNS service, configure it according to the [DynDNS documentation](https://dyn.com/dyndns/quick-guide.html), and then run the script:
`
bash
mkdir -p /etc/dynamic-1 && chmod 700 -R /etc/dynamic-1
`
3. **Set up a Heroku deployment:**
First, you need to install DynDNS on your server:
`
bash
sudo apt install dymn-daemon dymn-client
`
Then set up everything according to the provided instructions in this stack:
https://github.com/rogerschaefer/dymndr/issues/29
3. **Make sure you have the necessary dependencies installed:**
The dyn-dynshs
package is not included, so install it:
`
bash
sudo apt-get update && sudo apt-get install -y python pydynamn python-retry-exceptions python-pyznc
`
4. Compile and install the DynDNS service script (cf-dyndns.sh
):
`
bash
git clone https://github.com/rogerschaefer/dynamicserver.git /var/www/dynserver
sudo make -C dynserver/
sudo ./build DynDNSService binary
sudo python dynserver.py init
`
5. **Configure your service to start on boot:**
If the above command doesn't work directly, ensure a systemd
or similar service is in place and use:
`
bash
sudo cat > /etc/systemd/system/dynamic.service <[Unit]
Description=DynDNS Service
[Service]
User=www-data
ExecStart=/bin/bash -l /var/www/dynserver/scripts/ /bin/login -s
Restart=always
[Install]
WantedBy=multi-user.target
`
6. **Allow your DynDNS service to have read permissions on the file:**
First, you need to start and enable the dyn.dynamic.service as described above or use a default option like following command:
`
bash
sudo systemctl daemon-reload; sudo systemctl enable -f /etc/systemd/system/dynserver-service /var/www/dynserver/scripts/
sudo systemd-analyze disable --wait=/etc/SystemService/ * 10m inotify 2>
`
7. **Create a file edit (/usr/local/bin/cf-dyndns.sh
) to hold the cf-dyndns.sh
executable and set execute permissions for it:**
`
bash
sudo nano -R /usr/local/bin/cf-dyndns.sh
chmod +x /usr.local.bin/confed Cf-dyndns.sh
`
### Run cf-dyndns.sh
With a working DynDNS setup, there's no need to run the script again. However, one can create it and ensure proper execution of steps:
- Create your .conf
file according to [DynDNS Configuration](https://dyn.com/dyndns/config.html)
- Make sure cf-dyndns.sh
is in your ~/.local/bin
path
- You might need the Heroku credentials or a DynDNS account.
Remember, if everything goes right, this will successfully update your DNS settings according to the configuration you provided. However, always refer to [DynDNS documentation](https://dyn.com/dyndns/html/) for every step, especially configurations and how they can be customized based on the needs of your users or application.
When running cron jobs, consider adding a NO_REPLY
message when dealing with unexpected errors:
`
bash
schtask -F 'no_reply' -u your_username @daily DynDNS service update
`
In summary, run your script at a cron
job or add the necessary commands to make it happen immediately upon startup. Please find how it should be executed below and verify against specific instructions, especially about error messages and handling unexpected situation.
`
bash
#!/bin/bash
# Start your DynDNS service if it's not already running
if ! /etc/systemd/system/dynamic.service > /dev/null 2>&1; then
sudo systemctl daemon-reload && sudo systemctl enable -f /etc/systemd/system/dynserver-service /var/www/dynserver/scripts/
fi
# Update your DynDNS service and notify recipients via SMTP or whatever methods you choose to implement in your configuration.
`
Remember, all the configurations, dependencies and steps should be reviewed carefully before running these systemd` commands to ensure smooth operation with both your DynDNS instance and your Heroku deployment. Your update may still have varying requirements based on the specific setup including your server, dynnam services, Python application & heroku credentials, if they apply any other specifics you wish add here:
