Integrating and Managing Appliances

Micetro seamlessly integrates with DNS/DHCP server (MDDS) appliances, available in both hardware and virtual machine configuration. By integrating Micetro with appliances, you gain the power to effectively manage services, optimize deployment processes, and oversee day-to-day server operations, all through the intuitive Micetro user interface.

Once you have configured the initial network settings for your appliance and added it to your Service Management, you can interact with the services just as you would with other DNS and DHCP services within Micetro.

Appliances are accessed and managed in Service Management on the Admin page.

Adding a New Appliance to Micetro

Note

Before adding a MDDS appliance to Micetro, ensure that the appliance is configured in Micetro-mode and that interfaces are appropriately configured.

• To configure the appliance to be in Micetro-mode, follow the instructions for Configuring DNS/DHCP Servers for Micetro.

• To configure interfaces on the appliance, follow the instructions for Setting an IPv4 address and Setting an IPv6 address.

To add an appliance to Micetro, you must have the Administrator role.

To add an appliance:

1. Go to the Service Management tab on the Admin page, and select Add Service. The Add Service wizard opens.

   

2. Select Appliance.

3. Provide the host name for the appliance, which will also be used for the DNS and DHCP services hosted on the appliance.

4. Optionally, enter the IP address of the appliance. The appliance name will still be used when displaying appliance information.

5. Enable or disable appliance services. By default, DNS and DHCP services are activated. If you require remote access to your appliance for specific purposes, you can enable the SSH (Secure Shell) client.

6. Select Add. The appliance is added to the Appliances section, and its associated services are listed under DNS Services and DHCP Services.

Editing Appliance Name

You can change the name or IP address used to connect to your appliance. This is useful if you need to refer to the appliance by another name or if you are connecting to the appliance by an IP address and the IP address has changed.

To change the appliance name:

1. Go to the Service Management tab on the Admin page.

2. In the filtering sidebar, select Appliances, then select the specific appliance you wish to edit.

3. Select Edit appliance on either the Action or the Row … menu.

4. Modify the appliance’s name, and/or IP address (optional).
