Network Operating Systems-I

notes If your server is behind a cable/DSL router (such as a Linksys, DLink, or Netgear) or some other
type of firewall or proxy server, replace the line:
use=if, if=eth0
with the line:
use=web, web=support.easydns.com/utils/get_ip.php
This basically uses a page on EasyDNS’s Web site to display your ‘outside’ IP address. The
ddclient software will read the IP address off the returned HTML code and send it to EasyDNS.
It’ll do this periodically which is necessary with the changing IP addresses you get with cable
and DSL services.

Allowing dynamic DNS using the EasyDNS Web interface is simply a matter of clicking on
the “disabled” link as illustrated below and acknowledging the change on the subsequent
confirmation page.

Once you’ve got your configuration file set up and you’ve set your domain for dynamic DNS,
you can test your ddclient configuration to certify it’s working with the command:

ddclient -daemon=0 -noquiet -debug -verbose
If you use Apache’s virtual hosts feature to host multiple Web sites on your server and you have
multiple domain names registered with EasyDNS you can update the dynamic DNS for all the
domains simultaneously by separating each of the domains with a comma (,) like so:
# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf
pid=/var/run/ddclient.pid

protocol=easydns
use=if, if=eth0
server=members.easydns.com
login=bgates
password=luvlinux
my-last-name.net,moe.com,larry.com,curly.com
The EasyDNS Web interface let you to add/modify A records, MX records and priorities, aliases
(CNAME records), and even the time intervals in the SOA record, all by clicking on the “dns”
link shown in the figure above. The “nameservers” link takes you to a page which lists the
authoritative DNS server information (EasyDNS’s name servers) for your domain.

Did u know? How is the support for dynamic Dns is disabled?
