1.0 Introduction |
|
This document describes how to configure Domain Name System (DNS) parameters with KlasRouter. KlasRouter offers two options for configuring DNS, the Domain Name Relay Daemon (DNRD) and Dynamic DNS. Dynamic DNS is a feature that allows KlasRouter to register its IP Address with a Dynamic DNS Server so that external entities can resolve its domain name with the KlasRouter IP Address. This is important because the IP Address given to KlasRouter through a DHCP Server will probably change frequently, but with Dynamic DNS the changing IP Address will be mapped to a static domain name that external entities can resolve using normal DNS procedures. DNRD is a KlasRouter service that acts as a proxy in order to forward DNS requests. DNRD is started upon booting up KlasRouter and will automatically pull DNS Server information from a DHCP Server connected to the Ethernet WAN port. Alternatively, users can manually configure primary and secondary DNS servers and when a client on the Ethernet LAN requests a DNS lookup, KlasRouter forwards the request onto those DNS Servers. The following sections outline the steps needed to configure DNS with KlasRouter.

2.0 Configuration of KlasRouter |
|
2.1 Cable Connections
Prior to beginning, ensure the following cable connections have been properly secured:
- Power cord is plugged in and KlasRouter is on.
- Control Port Cable is connected to the PCs serial port.
- Control Port Cable is connected to the ‘Control’ port on the front of the KlasRouter.
To configure the KlasRouter, you must establish a HyperTerminal Session between a PC and the KlasRouter. Follow the instructions in KlasRouter Application Note Q10601 to successfully establish a HyperTerminal Session and open the KlasRouter Main Configuration Menu.The following sections outline how to activate, deactivate, edit and update the Dynamic DNS (DDNS) information. Follow the steps below to successfully configure DDNS on KlasRouter.
--------------------------
Dynamic DNS is currently deactivated.
Current Settings:
- Server: www.dyndns.org
- Protocol: dyndns2
- Login name: myloginname
- Password: mypassword
- My Address: myhost.mydomain.com
1) Activate Dynamic DNS
2) Deactivate Dynamic DNS
3) Edit Settings
4) Update DNS Server
Press 'x' to Return
Enter Option>1
Dynamic DNS is activated.Figure 1. Activating Dynamic DNS
- Enter ‘1’ to activate the Dynamic DNS feature using the current settings displayed, as shown in Figure 1.
- Press ‘Enter’ to return to the Dynamic DNS Configuration Menu.
.
- Enter ‘2’ on the Dynamic DNS Configuration Menu to deactivate the Dynamic DNS feature, as shown in Figure 2
Dynamic DNS Configuration -------------------------- Dynamic DNS is currently deactivated. Current Settings: - Server: www.dyndns.org - Protocol: dyndns2 - Login name: myloginname - Password: mypassword - My Address: myhost.mydomain.com 1) Activate Dynamic DNS 2) Deactivate Dynamic DNS 3) Edit Settings 4) Update DNS Server Press 'x' to Return Enter Option>1 Dynamic DNS is deactivated. |
Figure 2. Deactivating Dynamic DNS
- Press ‘Enter’ to return to the QoS Configuration Menu.
- Enter ‘3’ on the Dynamic DNS Configuration Menu to edit the Dynamic DNS parameters.
- The current status and Dynamic DNS settings will be displayed. Below that, a menu listing each parameter is available. Enter the number corresponding to the parameter you would like to edit. For example, in Figure 3 shown below, the login name is being changed from ‘myloginname’ to ‘klas’.
Dynamic DNS Configuration -------------------------- Dynamic DNS is currently deactivated. Current Settings: - Server: www.dyndns.org - Protocol: dyndns2 - Login name: myloginname - Password: mypassword - My Address: myhost.mydomain.com 1) Server 2) Protocol 3) Login name 4) Password 5) My DNS Address Press 'x' to Return Enter Option>3 Enter new login name ('q' to quit)>klas New Login Name: klas Press Enter to Return to Dynamic DNS Configuration |
Figure 3. Editing the Dynamic DNS Parameters
- Press ‘Enter’ to edit more Dynamic DNS parameters
- When finished editing the parameters, press ‘x’ to return to the Dynamic DNS Configuration Menu.
2.3.4 Updating the Dynamic DNS
Server
- Enter ‘4’ on the Dynamic DNS Configuration Menu to update the Dynamic DNS Server with the current parameters.
- Enter the interface you would like to send the information out of, as shown in Figure 4. This interface must have a route to the Dynamic DNS Server. After entering the interface information, KlasRouter will automatically attempt to contact the Dynamic DNS Server, authenticate the account and update the Server with the appropriate IP Address, as shown in Figure 4.

2.4 Configuring
the Domain Name Relay Daemon (DNRD)
The following sections outline how to start and stop the DNRD, as well as check the status of DNRD. Follow the steps below to successfully configure the DNRD on KlasRouter.
Domain Name Relay Daemon Configuration -------------------------------------- 1) Start DNRD 2) Stop DNRD 3) DNRD Status Press 'x' to Return Enter Option> |
Figure 5. DNRD Configuration Menu
- Enter ‘1’ to start DNRD.
- Enter the Primary DNS Server IP Address.
- KlasRouter will prompt you to indicate whether you want to add a Secondary DNS Server. Enter ‘y’ to add another DNS Server or ‘n’ to return to the DNRD Configuration Menu.
- If you opted to add a Secondary DNS Server from Step 5, enter the IP Address of that DNS Server. Figure 6 shows an example of the Primary and Secondary DNS Servers being entered.
Domain Name Relay Daemon Configuration -------------------------------------- 1) Start DNRD 2) Stop DNRD 3) DNRD Status Press 'x' to Return Enter Option> Enter DNS IP Address ('q' to quit)>68.87.71.226 Do you want to add a secondary DNS? (y/n/q)>y Enter Secondary DNS IP Address ('q' to quit)>68.87.73.242 DNRD activated with DNS: 68.87.71.226 and Secondary DNS: 68.87.73.242 Press Enter to Return to DNRD Configuration |
6. Starting DNRDFigure
- Press 'Enter' to return to the DNRD Configuration Menu.
- Enter ‘2’ from the DNRD Configuration Menu to stop the DNRD.
Domain Name Relay Daemon Configuration -------------------------------------- 1) Start DNRD 2) Stop DNRD 3) DNRD Status Press 'x' to Return Enter Option> DNRD is activated using DNS: 68.87.71.226 and Secondary DNS: 68.87.73.242 Press Enter to Return to DNRD Configuration |
