dyndns not being updated by ddclient
 
Hello everyone,

I have just installed and configured ddclient on my Ubuntu server to work with my dyndns. I decided to run a few tests to see if it was installed and working properly. What I did was log into dyndns.com with my account and directly modified my IP address to a bogus (but valid) address. I saved my changes. When I pinged myhost.dyndns.com it was pinging the bogus IP as expected. GOOD

I then ran ddclient -daemon=0 -noquiet -verbose thinking that it would update the entry to my real IP address. Well it doesn't. For some reason dyndns doesn't return the bogus address when ddclient is executed.

ddclient.conf is as follows
----------------------------

pid=/var/run/ddclient.pid
protocol=dyndns2
server=members.dyndns.org
login=mylogin
password='mypassword'
myhost.dyndns.com
use=web, web=checkip.dyndns.com, web-skip='IP Address'
daemon=600
syslog=yes
ssl=yes

result of sudo ddclient -daemon=0 -noquiet -verbose
---------------------------------------------------

Anyone know what I'm doing wrong?

I think I might have answered my own question. Because ddclient caches my real IP in a file and uses that to compare with the result of checkip.dyndns.com it doesn't see that there is a difference. I will assume that the process works when my IP acctually does change ... which it hasn't yet.
