ddns config...

I can't seem to get ddns to attempt to work.  'debug ip ddns update' shows nothing.  Here's what I have:

ip domain-lookup

ip name-server 192.168.1.2

ip ddns update method DynDNS

HTTP

  add http://username:password@members.dyndns.org/nic/update?system=dyndns&hostname=password@members.dyndns.org/nic/update?system=dyndns&hostname=<h>&myip=<a>   remove http://username:password@members.dyndns.org/nic/update?system=dyndns&hostname=password@members.dyndns.org/nic/update?system=dyndns&hostname=<h>&myip=<a>

interface Dialer1

ip ddns update hostname myhost.dyndns.org

ip ddns update DynDNS

Any clues?  I don't get any activity.

Re: ddns config...

Hi, it looks like some details are missing in your config, and not sure if you are using your user/password.

config t

  ip ddns update method

    HTTP

add

http://dataserve:Darahope@members.dyndns.org/nic/update?system=dyndns&hostname=&myip=

example: add

http://horizonsit:cyv6tiko@members.dyndns.org/nic/updatesystem=dyndns&hostname=kytc.dnsalias.net

    interval maximum 1 0 0 0 ----> (dd/hh/mm/sec)

    exit

  int fa0/0

    ip ddns update hostname

    ip ddns update

------------------------------------------------------------------------------------

Applying the configuration is :

interface Ethernet1

no ip ddns update DUM_Eth1 host 127.0.0.1

ip ddns update DUM_Eth1

exit

ip ddns update method DUM_Eth1

HTTP

  rem

http://172.16.59.2/cgi-bin/dns//

  add http://test:test1@members.dyndns.org/nic/update?system=dyndns&hostnametest1@members.dyndns.org/nic/update?system=dyndns&hostname

=&myip=

Please note:

test is your username given from your ddns server

test1 is your password

members.dyndns.org = the url of the ddns server

For you to be able to type the "?" symbol please use:   control  v  ?

For this to take effect we need to shut and no shut the interface.

-----------------------------------------------------------------------------------------

Useful commands/ debugs to verify the configuration

show ip host-list

show host x.x.x.x where x.x.x.x is the ip address of (say) members.dyndns.org

show running-config | incl host-list

show running-config | incl host

debug ip ddns update

show ip ddns update

show ip ddns update method

Hope this help.

Re: ddns config...

What I have actually ended up working.  But for some strange reason I have to actually reboot the router (maybe just reset the interface but can't do that since I'm doing it remotely) to make changes to ddns.  So, upon enabling ddns I have to reboot and to even change the URL I have to reboot also.  So, my working config in it's simplest form is like this:

ip ddns update method dyndns

HTTP

  add http://username:password@ members.dyndns.org/nic/update?system=dyndns&hostname=&myip=

interface Dialer1

ip ddns update hostname myhost.mydomain.com

ip ddns update dyndns
