ddclient DynDNS Updater - Perl Module Problems

I should mention I'm a linux noob.

I have tried to install ddclient to update DynDNS for me, I followed the instructions for ddclient. When I execute
ddclient -force
I get this error:-
FATAL: Error loading the Perl module IO::Socket::SSL needed for SSL connect.
FATAL: On Debian, the package libio-socket-ssl-perl must be installed.
Can't exec "sendmail": No such file or directory at /usr/sbin/ddclient line 1346.
ddclient: cannot execute command | sendmail -oi root.

So I ran CPAN
perl -MCPAN -e shell
and tried
install IO::Socket::SSL
I get a message to follow the dependancy for
Net::SSLeay
and I type yes and get errors.

I try to manually make using perl Makefile.PL and get this:-
Cannot determine perl version info from lib/Net/SSLeay.pm
Cannot determine license info from lib/Net/SSLeay.pm
* Could not find OpenSSL
If it's already installed, please set the OPENSSL_PREFIX environment
variable accordingly. If it isn't installed yet, get the latest version
from http://www.openssl.org/.**

What shall I do now any ideas??

Well it turns out I just needed to add a hash to make the line in ddclient.conf:-
#ssl=yes # use ssl-support. Works with
# ssl-library

Anyway next problem is to get ddclient to run on startup. I placed the file ddclient in /etc/init.d. The file /etc/init.d/ddclient runs the actual ddclient file, which is located at /usr/sbin.

I reboot and ddclient process is not there! It turns out the script rcS in /etc/init.d only starts scripts that begin with S! I changed the filename from ddclient to Sddclient and now the ddclient process is present when I reboot.

I'm thinking there must be a neater solution than this, can anyone point me in the right direction? Should I be using inittab or some other way????

Did you have to install perl on the MyWorldBook, or was it already there ?

It is : perl 5.8.8 ready !

Thanks for confirming. I thought perl was already installed.

When I try launching ddclient via /etc/init.d/ddclient, I originally got the following error:

Starting ddclient: /etc/init.d/ddclient: /usr/sbin/ddclient: /usr/bin/perl: bad interpreter: No such file or directory

So I created the following symbolic link to resolve the problem:

ln -s /usr/local/bin/perl /usr/bin/perl

But now I have an ownership problem with the /etc/ddclient/ddclient.conf file as follows:

Starting ddclient: WARNING: file /etc/ddclient/ddclient.conf: file /etc/ddclient/ddclient.conf must be accessible only by its owner (fixed).

Did you chown the /etc/ddclient/ddclient.conf file in any way ?

Strange. I set the permissions to rw (600) on the /etc/ddclient/ddclient.conf file, and it now works :-)

I am just wondering if anyone is having the same minor issue than me. I contacted DynDNS about this, so hopefully they have an answer too.

Basically, ddclient is installed and seems to be running okay (I can see it when I execute ps aux). I managed to get ddclient to start at boot time too, with a file /etc/init.d/S40ddclient.

My issue I am having is that the ddclient actually only updates my IP when I reboot the box. It seems that /etc/init.d/S40ddclient restart and the ddclient daemon (set to update every 600 seconds) do not update my IP. Only rebooting the box updates my IP.

Any ideas ?
