Abandoned

This project is likely going to be abandoned with the approval of a pull request to add the same functionality directly to Vesta Control Panel itself. If you would help get this pushed into Vesta, please check out the pull request found at outroll/vesta#1477 and test and add comments indicating that you would use such a feature.

Dynamic DNS for Vista Control Panel

Requirements

1. A server with a static public IP address running Vesta Control Panel
2. A Linux machine on a network with a dynamic public IP address. (E.g. Raspberry Pi)
3. A domain name.

Usage

System with the dynamic public IP address

• Must have an ssh client installed.
• Must have sshpass installed if you are using password authentication.
• Place ddns-client.sh (this file) into ~/scripts
• Add the following command to the user's cron at your frequency of choice:

bash ddns-client.sh {URL to index.php} {server domain name} {vesta username} {domain} {subdomain} {record type} {OPTIONAL server admin username} {OPTIONAL server admin password}

• The optional fields and highly discouraged. SSH key authentication is strongly recommended.

System with the static public IP address

• An installation Vesta Control Panel configured with the domain name you wish to use.
• Place index.php into /home/{username}/web/{domain name}/{public_html or public_shtml}/ip (or public_shtml, dependent if you are serving SSL from a different folder)
• Place ddns-server.sh into ~/scripts of your admin user home directory.
• Edit ~/.bashrc in the admin user home directory to include the contents of the included .bashrc file.

Both Systems

• OPTIONAL BUT RECOMMENDED: Set up SSH key for ssh authentication between the two systems. See http://www.linuxproblem.org/art_9.html for more information.

Warning

One means of using this script involves the storing of a password in plaintext in the user's crontab. This practice is generally seen as insecure. Ideally, you would use an RSA key to connect instead for better security.

To Do

• Reduce the requirements on the client side. Such that all that would be required to call is a simple CURL command to a specific URL accompanied with a token.
