ddclient to update dynamic DNS entries at a dynamic DNS service

I have a linux machine setup in our high school computer lab. I've set up
an account with a dynamic DNS service and have given the computer a hostname
supported by the service. I downloaded and installed a linux client called
ddclient to update the dynamic DNS IP address entries so that the hostname
always points to the linux box. IP addresses are dynamically assigned by a
dhcp server in our school district. The question I have is does ddclient
start automatically when I start the linux computer? Here are the
installation instructions that I followed. Ddclient was downloaded as a tar
file, which I extracted. I copied the ddclient file to /usr/sbin/ and I
copied the configuration file, ddclient.conf, to /etc/ddclient.conf and
customized it to my dynamic dns service provider. Are those steps
sufficient to enable ddclient to run automatically when I start linux? If
not, what else do I need to do? There is reference in the readme file about
running ddclient as a daemon, but no specific instructions about that for
the installation instructions I followed, unless copying the files to their
locations described above accomplishes that.

No, unless the installer put a boot-time script in /etc/init.d or /etc/rc.d,
depending on your distro. You should start by reading up on the Linux boot
process-- try http://www.tldp.org/LDP/intro-linux/...ect_04_02.html.

I have a similar setup with ipcheck (another DDNS client), and I run it both
at boot, and daily from a cron job.

Good luck,
Andrew.
