2.2.3.1 Configuring the Network

If the server is not configured with the DefaultFixed network configuration profile, then the network profile configuration menu is displayed.

Network Configuration
*** ERROR: The DefaultFixed network profile is not enabled.
 
----------------------------------------------------------------------
 
Network Profile Configuration
 
The system must be configured with the DefaultFixed network
profile. You can manually configured the DefaultFixed network
or you can use this tool to do the configuration. This tool
will configure a single network interface, all other network
interfaces will be unconfigured.
 
Do you want to use this tool to configure the network?
 
  1) Yes, use this tool to configure the network
  2) No, I will configure the network manually
 
Choice (1-2) [1]:

To use the tool to enable the DefaultFixed network configuration profile and configure the network, select 1.

To skip the configuration of the network, select 2. In which case, you must manually enable the DefaultFixed network configuration profile and configure the network.

When configuring the network, if you are not connected to the system console then a warning is displayed.

!!! WARNING !!!
 
You are not connected to the system console. Reconfiguring
the network can disrupt your remote connection to the server
and you can lose the remote access to the server.
 
!!! WARNING !!!
 
Are you sure that you want to continue?
 
  1) Yes, continue and configure the network
  2) No, cancel the configuration of the network
 
Choice (1-2):

To continue the network configuration, select 1.

Warning

Configuring the network can disrupt current network connections to the server and you can potentially lose your connection to the server. So it is safer to configure the network from the system console.

To cancel the configuration of the network, select 2. Then connect to the system console, and restart the configuration by running the ovs-agent-setup configure again.

The Oracle VM Management Interface menu is displayed.

Collecting information about network interfaces...
 
----------------------------------------------------------------------
 
Oracle VM Management Interface
 
Choose the network interface to use for the management of this
machine.
 
  1) net0: 00:14:4f:e3:0f:12 (nxge0)
  2) net1: 00:14:4f:e3:0f:13 (nxge1)
  3) net2: 00:14:4f:e3:0f:14 (nxge2)
  4) net3: 00:14:4f:e3:0f:15 (nxge3)
 
Interface (1-4) [1]:

Select the network interface to use for the management of the server.

The Network Interface Configuration menu is displayed.

IPv4 Configuration for net0
 
  1) Dynamic IP configuration (DHCP)
  2) Manual address configuration
 
IPv4 Configuration (1-2) [1]:

To configure the network interface with DHCP, select 1. To configure the network interface with a static IP address, select 2.

Configuring the Network with DHCP

If the network interface is to be configured with DHCP, then the Hostname Configuration menu is displayed.
```
Hostname Configuration
 
If your system is part of a larger network where hostnames
are assigned by DHCP, select automatically via DHCP.
Otherwise, select manually and enter a hostname for your
system.
 
  1) automatically via DHCP
  2) manually
 
Hostname Configuration (1-2) [1]:
```
If the server uses DHCP to assign its hostname, select 1. If the server has its own hostname, select 2. Then, at 'Hostname' prompt, enter the hostname to be used.
The Oracle VM management interface configuration is displayed:
```
Oracle VM Management Interface
 
  Interface: net0
  IP Address: DHCP
  Hostname: DHCP
 
Are these parameters correct?
 
  1) Yes, configure the network with these parameters
  2) No, enter new parameters for the network configuration
 
Choice (1-2):
```
Select 1 to confirm that parameters are correct. The tool then configures the network. Select 2 if you want to enter new parameters, the process to configure the network then restarts from the beginning.

Configuring the Network With a Static IP

If the network interface is to be configured with a static IP configuration, then the tool requests to enter IP configuration information.

IP Address [192.168.1.10]:
  Prefix (Netmask) [255.255.255.0]:
  Gateway [192.168.1.1]:
  Primary DNS [192.168.168.168]:
  Secondary DNS [192.168.169.169]:
  Hostname [foo.example.com]:

The Oracle VM management interface configuration is displayed:

Oracle VM Management Interface
 
  Interface: net0
  IP Address: 192.168.1.10
  Prefix (Netmask): 255.255.255.0
  Gateway: 192.168.1.1
  Primary DNS: 192.168.168.168
  Secondary DNS: 192.168.169.169
  Hostname: foo.example.com
 
Are these parameters correct?
 
  1) Yes, configure the network with these parameters
  2) No, enter new parameters for the network configuration
 
Choice (1-2):

Select 1 to confirm that parameters are correct. The tool then configures the network. Select 2 if you want to enter new parameters, the process to configure the network then restarts from the beginning.

Configuring the Hostname

The setup tool checks if the server is configured with a valid hostname, that is a hostname different from "localhost" and that resolves to an IP address different from 127.0.0.1.

If the hostname of the server is set to localhost, then an error is displayed.

*** ERROR: The server has an invalid hostname (localhost).
 
----------------------------------------------------------------------
 
Server Hostname
 
The server has no hostname or an invalid hostname. Use
the "hostname" command to check and configure the hostname
of the server. You might also want to check the network
configuration of the server.
 
Press <return> to continue...
*** ERROR: The server has an invalid hostname (localhost).

After the setup tool exists, you must use the hostname command to configure the hostname of the server.

If the hostname resolves to the 127.0.0.1 then an error is displayed and the /etc/hosts file is updated to not resolve the hostname to 127.0.0.1.
```
*** ERROR: The server hostname (foo) should not resolve to 127.0.0.1.
Configuring /etc/hosts to not resolve foo to 127.0.0.1
Updating /etc/inet/hosts, the previous file is backed up as /etc/inet/hosts.20121128190648
```
When the setup tool updates the /etc/hosts file, the original /etc/hosts file is backup as /etc/inet/hosts.<date-and-time>.

If the hostname does not resolve to an IP address then an error is displayed.

*** ERROR: The server hostname (foo) does not resolve to an IP address.
 
----------------------------------------------------------------------
 
Server IP Address
 
The server hostname does not resolve to an IP address.
 
  hostname: foo
 
Update the /etc/hosts file or the name service so that the
hostname of the server is resolved to a valid IP address.
You might also want to check the network configuration of
the server.
 
Press <return> to continue...
*** ERROR: The server hostname (fooxxx) does not resolve to an IP address.

After the setup tool exits, you must update the /etc/hosts file or your name service so that the hostname resolves to a valid IP address. For more information about naming services, see the Working With Naming and Directory Services in Oracle Solaris 11.1 documentation at:
