ddclient: Install and Configure to update Dynamic IP Change

STEP 1:
Download latest ddclient from sourceforge.net

$ wget http://download.sourceforge.net/ddclient/ddclient-3.8.1.tar.gz

STEP 2:
Expand the tarball

$ tar zxvf ddclient-3.8.1.tar.gz

STEP 3:
You will have ddclient-3.8.1 directory in you current directory. You have to copy ddclient to /usr/sbin directory.

$ cp ddclient /usr/sbin

STEP 4:
Create a directory for ddclient configuration file under /etc

$ mkdir /etc/ddclient


STEP 5:
Now, we have to create a configuration file for ddclient.

$ nano /etc/ddclient/ddclient.conf

and, put configuration as shown below.

# Configuration file for ddclient generated
#
# /etc/ddclient.conf

daemon=300
pid=/var/run/ddclient.pid
ssl=yes
protocol=zoneedit1
use=if, if=ppp1
server=dynamic.zoneedit.com
login=your-zoneedit-login-name
password='your-password'
www.domain.com
subdomain.domain.com
mail.domain.com

### EOF: ddclient.conf


My configuration file using ppp1 as reference for IP number changes, use=if, if=ppp1



STEP 6:
Follow this commands to test, start and set ddclient in daemon mode.

$ ddclient -daemon=0 -query
$ cp sample-etc_rc.d_init.d_ddclient /etc/rc.d/init.d/ddclient
$ /sbin/chkconfig --add ddclient


STEP 6:
Create ddclient cache directory

$ mkdir /var/cache/ddclient

ddclient will log cache in the directory under ddclient.cache filename.


STEP 7:
Test your config

$ ddclient -daemon=0 -debug -verbose -noquiet

All done...
