I don't run ddclient personally, so I can't supply you with a sample
conf file, but here is a list of troubleshooting tips I stumbled onto:
TROUBLESHOOTING:
1. enable debugging and verbose messages.
$ ddclient -daemon=0 -debug -verbose -noquiet
2. Do you need to specify a proxy?
If so, just add a
proxy=your.isp.proxy
to the ddclient.conf file.
3. Define the IP address of your router with fw=xxx.xxx.xxx.xxx in
/etc/ddclient.conf and then try
$ ddclient -daemon=0 -query
to see if the router status web page can be understood.
4. Need support for another router/firewall?
Define the router status page yourself with:
fw=url-to-your-routers-status-page
fw-skip=any-string-preceeding-your-IP-address
ddclient does something like this to provide builtin support for
common routers.
For example, the Linksys routers could have been added with:
fw=192.168.1.1/Status.htm
fw-skip=WAN.*?IP Address
OR
Send me the output from:
$ ddclient -geturl {fw-ip-status-url} [-login login [-password
password]]
and I'll add it to the next release!
ie. for my fw/router I used:
$ ddclient -geturl 192.168.1.254/status.htm
5. Some broadband routers require the use of a password when ddclient
accesses it's status page to determine the router's WAN IP address.
If this is the case for your router, add
fw-login=your-router-login
fw-password=your-router-password
to the beginning of your ddclient.conf file.
Note that some routers use either 'root' or 'admin' as their login
while some others accept anything.

USING DDCLIENT WITH ppp
If you ar using a ppp connection, you can easily update your DynDNS
entry with each connection, with:
## configure pppd to update DynDNS with each connection
cp sample-etc_ppp_ip-up.local /etc/ppp/ip-up.local
Alternatively, you may just configure ddclient to operate as a daemon
and monitor your ppp interface.
-------------------------------------------------------------------------------
USING DDCLIENT WITH cron
If you have not configured ddclient to use daemon-mode, you'll need to
configure cron to force an update once a month so that the dns entry
will
not become stale.
## configure cron to force an update twice a month
cp sample-etc_cron.d_ddclient /etc/cron.d/ddclient
vi /etc/cron.d/ddclient
-------------------------------------------------------------------------------
USING DDCLIENT WITH dhcpcd-1.3.17
If you are using dhcpcd-1.3.17 or thereabouts, you can easily update
your DynDNS entry automatically every time your lease is obtained
or renewed by creating an executable file named:
/etc/dhcpc/dhcpcd-{your-interface}.exe
ie.:
cp sample-etc_dhcpc_dhcpcd-eth0.exe
/etc/dhcpc/dhcpcd-{your-interface}.exe
In my case, it is named dhcpcd-eth0.exe and contains the lines:
#!/bin/sh
PATH=/usr/sbin:/root/bin:${PATH}
logger -t dhcpcd IP address changed to $1
ddclient -proxy fasthttp.sympatico.ca -wildcard -ip $1 | logger -t
ddclient
exit 0
Other DHCP clients may have another method of calling out to programs
for updating DNS entries.
Alternatively, you may just configure ddclient to operate as a daemon
and monitor your ethernet interface.
-------------------------------------------------------------------------------
USING DDCLIENT WITH dhclient
If you are using the ISC DHCP client (dhclient) or thereabouts, you can
update
your DynDNS entry automatically every time your lease is obtained
or renewed by creating an executable file named:
/etc/dhclient-enter-hooks
ie.:
cp sample-etc_dhclient-enter-hooks /etc/dhclient-enter-hooks
Edit edit /etc/dhclient-enter-hooks to change any options required.
Alternatively, you may just configure ddclient to operate as a daemon
and monitor your ethernet interface.
