Those are just to highlight the changes. BBB Fixed bug dealing with no IP address returned from dyndns provider Save the current IP address that was returned by router or external web request. I commented out the old split line but this could be removed. The following line is from the unpatched code. You could, of course, try installing the complete 3. Just wanted to say thanks for the tutorial.

I actually came across it whilst setting up 'ddclient' for a Lubuntu installation on a PC, but I found your tutorial and its descriptions of what exactly is going on and why to be helpful in the extreme. I'd like to echo the comments elsewhere that your approach here is atypical of the normal "here's a list of instructions" way of doing this, and the fact that you've taken the time to explain what's going on has made me feel like I've learned something.

Breadcrumb Home. Use this command to install ddclient: sudo apt-get install ddclient Enable dynamic DNS with your DNS provider If you're not using namecheap, then this section will be different, but the concept is the same regardless of DNS provider. For namecheap the value is "namecheap" server is the hostname of the dynamic DNS server.

The dynamic DNS servers used by namecheap are located at "dynamicdns. Leave the single quotation marks around the string. The last line is the subdomain to be modified. In my case this was backup , for backup.

If you wanted to update your root domain, you would put an symbol on this line instead WAN IP discovery The above configuration would work fine if ddclient was installed on a router, since the router knows your WAN IP address. Getting your WAN IP from your router's status page Although I haven't opted for the router firmware method, I think it's quite interesting and worth discussing.

Getting your WAN IP address from a web service The web method involves ddclient querying one of the many "what is my ip" type web services on the internet, and extracting your IP address from the page returned. Secure submission Remember how I said anyone with your dynamic dns password can change your DNS records?

Add new comment. Thanks in advance.. Use a longer time period in cron Thanks : that's exactly what I'm going for. Good question. I guess they just don't want you spamming them with unneccessary requests if everyone forced an update every hour that would add up to a lot of traffic pretty quickly , but I doubt you'll get in trouble for doing it once a week or month.

If you think about it, when you reboot your server ddclient's IP address cache is probably cleared, so it must send a probably unneccessary request then.

They're not going to ban people for rebooting their servers every week, so running a weekly job is probably fine. Your call, though! Thanks for the comment : Sam. How about this SSL problem? Install libio-socket-ssl-perl Are you sure they told you to buy a certificate? That was terrible advice if so - ddclient is the client in this case so no certificate is required. Do you have libio-socket-ssl-perl installed? If not, install it and re-test.

Btw, really nice guide good job! Thnak you I had installed that but after I installed ddclient. Welcome Strange, it shouldn't make any difference which order you install the packages in - did you get an error during installation the first time?

You're welcome as always : Sam. Try deleting the cache Hey Amigo, try deleting the cache, or changing the ip in the cache. I had the same problem. I was having the same problem and this worked! Thanks for this helpful tutorial! Hey, nice laid out tutorial! Thanks for the feedback, it's Thanks for the feedback, it's really rewarding to know the tutorials have been useful : Sam.

But when it comes to installing ddclient, there's some oddity going on actually two : When doing a fresh setup of ddclient and on entering my details FQDN, DDNS server, username, password the automated script invariably tells me to re-enter my pwd, although I have taken every care to enter them exactly the same both time around. Many, many thanks!

I don't know why the order should matter, but it does seem to make a difference sometimes. I think you're right Yeah I think you're right, I guess no connection is made to the dynamic dns server unless the IP address actually needs to be changed. Maybe run ddclient with the force option and see if you get the SSL message in the output? Good one Great post, very useful! Thank you very much! I thought this info might be helpful to someone. Great tutorial and a ddclient question First great tutorial.

Thanks, Burt. How often does it try to How often does it try to update your IP address even though it hasn't changed? It was doing it every time It was doing it every time the interval I had set fired off.
