Hello empty forum,

Question for anyone here. How do I update a DNS field with a URL redirect?

I tried this on a unix command line:

echo "GET /update.asp?u=$1&p=$2&hostname=www.seiende.com&myip=$3" | openssl s_client -quiet -connect http://www.changeip.com:443 &/var/log/dns/updatedns

Nothing seems to update however. The third parameter (new URL) would be something like "1.1.1.1:81".

Hello,

The update system will only update A and CNAME records, not URLs. There is another way to accomplish what you are doing though, see here:

Create the following structure: (or name it however you like)

ip.4mydomain.com points to 24.1.2.3 (A)
http://www.4mydomain.com points to 'ip.4mydomain.com:81' (URL)
root of 4mydomain.com points to 'ip.4mydomain.com:81' (URL)

Now all you have to do is dynamically update the IP.4MYDOMAIN.COM hostname with your correct IP, and the other hostnames follow along. Also, if you use FTP, SSH, etc, then use the IP hostname instead of www or the root record, otherwise connections will hit our redirect server.

I didn't do exactly as your example but all I did was change "www.mydomain.com" to have a value of "mydomain:81". Works great. I needed this since my new ISP filters port 80. Thanks!
