From rPath Wiki
Appliance Administration --> Configure Networking
The rPath Appliance Platform Agent (rAPA) includes a Configure Networking plugin which is enabled by default. In this plugin, a rAPA user can view and edit the appliance network configuration, including:
- Appliance host name and Gateway
- DNS search domain
- DNS servers
- IP address, netmask, and gateway for each network interface, as well as specify whether to get this information from a DHCP-enabled server.
Use the following steps to configure networking:
- Access and log in to the rPath Appliance Platform Agent web interface.
- Click Configuration from the rAPA menu at the left.
- Click Configure Networking from the expanded menu.
- Complete the fields in the interface using the sections following these steps as a reference.
- Click Save.
 | Changes to host name and other DNS settings take effect immediately, and changes to network interfaces take effect if you click Apply when prompted for confirmation, or if you click Restart after saving. |
Appliance Host Server
- Obtain hostname servers from DHCP? -- Select whether the hostname that the appliance should use is provided automatically by DHCP. If you select No, type the desired host name in the text box provided.
- Host Name -- Fully Qualified Domain Name (FQDN) of the server. If DHCP is Yes this should be assigned by the DHCP Server.
- Gateway -- Use this to provide the gateway for the network segment on which the interface resides.
 | If the hostname changes, and there is an SSL certificate, the appliance agent should prompt you to update that certificate using the Regenerate button on the Upload SSL Certificate page. |
DNS Servers
Complete the DNS configuration for the appliance, including the following items:
- Obtain DNS servers from DHCP? --- Select whether the DNS servers that should be used are provided automatically by DHCP. If you select No, type the desired DNS server in the text box provided.
- DNS servers -- If you select No to obtaining DNS servers from DHCP, specify one or more DNS servers in this field. Click Add server to add a new server entry, and click the X beside the entry to delete it. Modify the entry directly to change it.
- Search domain -- Use this to designate one or more domains to search automatically during network interactions when the destination host is not specified with a fully qualified domain name. For example, if the appliance uses the search domain example.com, and the appliance attempts to find appliance1, the appliance will search for appliance1.example.com. Include as many search domains as the appliance requires, separated by spaces and first-to-last in the order in which they should be searched.
Network Interfaces
The Network Interfaces part of Configure Networking lists each network interface and its corresponding MAC address. The first interface is typically named "eth0" for the first Ethernet interface. Each section includes the following configurable fields:
- Obtain device configuration from DHCP? -- Select whether this interface should obtain its settings automatically by DHCP. If you select No, complete the IP address, Netmask, and Gateway text boxes with static entries.
- IP address -- Use this to designate a valid IP address for the network interface.
- Netmask -- Use this to provide the network mask for the network segment on which the interface resides.
- MAC Address --- Reports the Hardware MAC Address of the Network Interface Card assigned to each device.
