5.15 Configuring Dynamic DNS Client (DynDNS Client)
If some host has a dynamic IP address that keeps changing frequently, it is difficult to
keep updating the IP record that is associated with the domain name of this host in the
zone files. This will result in non-accessibility of this host on the Internet. Dynamic DNS
service allows to keep mapping of a dynamic IP address of such host to a static hostname.
Dynamic DNS services are provided by many websites. The host needs to register with
some website and get a domain name. When the IP address of the host changes, it just
needs to send a message to the website that's providing dynamic DNS service to this host.
For this to work, an automated update client needs to be implemented. These update
clients send update messages to the servers whenever there is some change in the IP
address of that host. Then, the server updates the entries for that host and replies
back with some return code.
To configure the Dynamic DNS Client settings, go to
Configuration
menu and click on
DynDNS client
. The
Dynamic DNS
page is displayed.
On this page you can see the defined DynDNS interfaces.
To add a new DynDNS interface, click on the link
Add a new dyndns interface…
.
The Dyndns: Add New Interface page is displayed.
his page allows you to:

which this entry defines the Dynamic DNS profile.
This parameter represents the name of the Dynam
provider where you have registered and the type of service. This

Chapter 5: Configuring the CopperJet
parameter accepts these values: dyndns, dyndnscustom, dyndns-
static, and tzo.
User Name:
Username registered at service provider. tzo requires mail ID as
the username.
Password:
Password provided by service provider.
Host Name:
This is the hostname that you specified while registering with your
service provider. This hostname remains fixed, while the IP
address mapping to this hostname changes.
Note:
Only one hostname is allowed per Dynamic DNS interface.
Offline (DYNDNS only):
If enabled, the service provider redirects browsers to its own site if
the registered host is currently offline.
URL
(DYNDNS only):
Specifies the URL of the host.
Wildcard (DYNDNS only)
: Specifies whether Wildcard aliases are to be resolved or not.
Mail Exchanger (DYNDNS only):
Specifies a Mail Exchanger (MX) to which the records for a
specific domain have to be mailed.
Connectiontype (TZO only):
Specifies the kind of connectivity the host has, such as LAN,
Cable modem, or Dial-up modem. This sets the cache time for
the hostname at TZO.
Note: Before using DYNDNS, you need to be registered to a Dynamic Service Provider.
At the moment 2 Dynamic DNS Service Providers are supported (
www.tzo.com
,
www.dyndns.com
).

5.16 Configuring Simple Network Time Protocol (SNTP) Client
Configuring your device as an SNTP client allows you to obtain accurate
time/date information from an associated SNTP server. If you are not attached
to an SNTP server, you can set the time/date on your own device instead.
To configure the
SNTP Client settings
,
go to
Configuration
menu
and click on
SNTP client.
The
SNTP client
page is displayed.
This page displays the default SNTP Client settings:
• Universal Time Coordinate (UTC), with no SNTP server set or synchronized to
• Synchronization mode disabled.
• Received packet response timeout value set to 5 seconds, and retry value set
to 2.
To configure SNTP:
1
At the NTP servers section, add the NTP server that you want your client to
obtain information from.
2
At the SNTP Client Mode Configuration Parameters section, select the SNTP
Synchronization mode(s) by clicking on the Unicast Mode Enabled, Anycast
Mode Enabled or the Broadcast Mode Enabled radio button. Click Set Mode.
