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.
