HI,

Plese refer this page howto do it:

http://www.petri.co.il/csc_configuring_dynamic_dns_in_cisco_ios.htm

please configure update:

interval maximum 1 0 0 0

Best regards,
Istvan

Hi

what configuration do you have on the WAN interface?

nothing......

please di it step by step as the link said....

you'll need

1) in global configuration
ip domain name <your domain name>


2)
ip ddns update DYNDNS

3) your router will need a method of resolving "members.dyndns.org"

on the interface you want to perform dynamic dns.

4)
you can also perform a ddns debug with the following command.

deb ip ddns update

don't forget the "term mon" if you doing this from telnet or ssh otherwise you won't see the debug results.

My previous post is incorrect.

1) in global configuration
ip domain name <your domain name>

2)
ip ddns update DYNDNS
on the interface you want to perform dynamic dns.

3) your router will need a method of resolving "members.dyndns.org"

4)
you can also perform a ddns debug with the following command.

deb ip ddns update

don't forget the "term mon" if you doing this from telnet or ssh otherwise you won't see the debug results.

Still does not work. Here is what I get after I turned on debug ip ddns update. Here are some odd things that I noticed; right after DATA START it sas abuse, what is that?
I also see Router.charter.com several times. My ISP is Charter, but what does that have anything to do with it.

Ok don't worry about the abuse. I figured that one out. I had set the update interval for 30 seconds so I can constantly see the changes that I made. So the hostname was blocked for abuste. I just fixed it on DynDNS website.

Hi,

I think you need to substitute your username and password in the http URL. Did you create an account when you registered with dyndns.org?

 

Which name are you trying to register?

ping emilgas.gotdns.com

Is the problem resolved?

well, I do have my username and password in the URL it just that I took it out before posting it. You got the reply back from emilgas.gotdns.com because I manually update the dns.
But here is what I got another abuse letter from dyndns because my router is trying to update frequently. So I know my router is doing what it is supposed to do, but not sure why it is not actually updating the DNS.
Humm.... something is wrong with their service and cisco

it is working with cisco, we use it, and it is working....

Good.

was ip ddns update DYNDNS missing from your WAN interface?

example:

ip ddns update method dyndns
 HTTP
  add http://xxxx:yyyyy@members.dyndns.org/nic/update?system=dyndns&hostname=<h>&myip=<a>
  remove http://xxxx:yyyyy@members.dyndns.org/nic/updatesystem=dyndns&hostname=<h>&myip=<a>
!

interface FastEthernet4
 description outside interface
 ip dhcp client update dns server none
 ip ddns update dyndns

No it was there. Whatever was mentioned above I had it. My problem is mysterious.
But I was missing the ? in the following line under IP DDNS UPDATE METHOD DYNDNS
add http://username:password@members.dyndns.org/nic/update?system=dyndns&hostname=myhost.gotdns.com&myip=<a>

I have one question for you
The last part of the url has hostname=<h>&myip=<a> right?
where does it get the <h> from? is it the hostname of the router that is specified by the hostname command or it is the ip domain-name command?
is it better to just but the hostname in the URL rather than <h>? For example
'http://username:password@members.dyndns.org/nic/update?system=dyndns&hostname=emilgas.gotdns.com&myip=<a>

I think its what you specify with the following command on the interface

ip ddns update hostname example.dyndns.org

but I think you've hardcoded yours in the URL which is fine.

I have ip ddns update dyndns statement under my interface just like Ikalmar mentioned above

You need both

ip ddns update hostname emilgas.gotdns.com
ip ddns update DYNDNS

I have exactly like you have upthere, Except I changed the interval max and min to 7 0 0 0 for it to update at leaset once a week. Now how will my router know if the IP address changed? Usually it changes everytime you reload the router. Will the DynDNS method run everytime it has been reloaded.
Now I'm going to have to wait 7 days before I can actually see if it had been updated? Last time I set it to update every hour, and I got an abuse notification. LOL
The only confirmation I have is to look at the DynDns website directly to see when it actually got updated. (LOOK Below)

Every time your router gets a new dhcp lease it should send a dynamic dns update (and every seven days of course). Have you asked dyndns.org why your receiving the abuse message?

please can you post another debug.

thanks.

Q: What Is An Abusive Update?
A: Updates should only be performed when your IP address has changed. We allow users to modify or "touch" their host every 28 days to prevent their hosts from expiring. Everything else is abusive.

make sure you set your update intervals to 28 days

interval maximum 28 0 0 0
interval minimum 28 0 0 0
