When a server is behind a firewall I want to know when the server's public IP address changes, and to communicate it back to my DNS servers at dns.he.net.
I need to know the outside IP address, not the private IP address of the server itself.
DDNS on Debian servers
DOES NOT WORK FOR BAREIS -- Beldon has multiple IP addresses and manages them.
HE.net part: Create a key. You have to create a key on the DNS server so that it will trust updates coming from the Debian server.
- Log into dns.he.net
- Go to the appropriate domain
- Click on the entry for the server (create one if it does not exist)
- Check the box "Enable entry for dynamic DNS. This will also clear the current IP address and set TTL to 5 minutes.
- Click Update.
- There will now be a "recycle" type icon for the entry. Click on it to either enter a key or generate a random key.
Debian part: Install and configure a DDNS package.
- sudo apt-get install ddclient
