I'm using ddclient v. 3.7.3 to update my IP address using DynDNS.  My configuration
is pretty standard -- see the pastebin link below.  According to the debugging
messages, I'm not having any problem getting my current IP address from
checkip.dyndns.org (I checked the address and it is correct) and update url
for DynDNS contains that same correct IP address.  However, the cache file contains
a blank IP entry ("IP=", see the config file listed in pastebin below).  Subsequent
runs throw this error:

"WARNING:  file /var/cache/ddclient/ddclient.cache, line 3: Invalid Value for
keyword 'ip' = ''"

This makes sense considering the IP address isn't being written to the file.
If I manually input an IP address in that file (say IP=1.2.3.4 or whatever),
the error goes away.  However, subsequent runs not only do not throw any errors
but do not update the value in the cache.

This is all very strange.  I took a look at the code and found that if I added
to IP address to %config at a strategic location, it seems to correctly update
the IP address in the cache file (see the third pastebin link below).  This
isn't a solution to this problem, whatever it may be -- but it might point you
in the right direction.  Please let me know if I can provide any more
information.
