Article Summary

Configure the primary senhasegura network interface to reach the Web interface, Proxies, and Webservices.

Caution

This functionality replaces the need for localhost login with the user 'orbit'.

When configuring the network interface, you will need to restart the server to apply the settings.

mt4adm@vmdf-giskard:~$ sudo orbit network --help
Usage: orbit network

Network settings tools

Flags:
      --help                Show context-sensitive help.

  -i, --interface=STRING
  -a, --address=STRING
  -m, --netmask=STRING
  -g, --gateway=STRING
      --reboot              Reboot the machine
      --force               Force the command execution, never prompt

List current configuration

The orbit network –show command displays the network settings currently applied.

mt4adm@vmdf-giskard:~$ sudo orbit network --show

Without the arguments, the user is presented with fields to configure the desired network interface.

This example shows how to configure the primary interface with DHCP.

mt4adm@vmdf-giskard:~$ sudo orbit network
Use the arrow keys to navigate: ↓ ↑ → ←
? Choose an interface to configure:
▸ eth0

? Network settings:
static
▸ dhcp

? Are you sure you want to proceed? [y/N] y
Done!
No errors reported


Info

If you set the senhasegura IP to DHCP, the DNS configuration (both via the screen and via command) may not work if configured as the Operating System default and made available in the OVA.

To change DNS, you need to configure a static IP.

This second example shows how to configure the interface with a static IP.


mt4adm@vmdf-giskard:~$ sudo orbit network
Use the arrow keys to navigate: ↓ ↑ → ←
? Choose an interface to configure:
▸ eth0

? Network settings:
▸ static
dhcp

✔ IP Address: 172.17.182.204
Netmask: 255.255.255.240
Gateway: 172.17.182.193

? Are you sure you want to proceed? [y/N]

Done!
No errors reported

You can also provide the configuration details as command line arguments. This way, the interaction is reduced.

mt4adm@vmdf-giskard:~$ sudo orbit network  
    --interface=eth0  
    --address=172.17.182.204  
    --netmask=255.255.255.240  
    --gateway=172.17.182.193

Use the arrow keys to navigate: ↓ ↑ → ←
? Choose an interface to configure:
▸ eth0

? Network settings:
▸ static
dhcp

? Are you sure you want to proceed? [y/N]

Done!
No errors reported

Restart the server to apply the settings

Use the command orbit network –reboot so the server restarts immediately after entering the network configuration. Use it with caution.

mt4adm@vmdf-giskard:~$ sudo orbit network --reboot

Use the arrow keys to navigate: ↓ ↑ → ←
? Choose an interface to configure:
▸ eth0

? Network settings:
static
▸ dhcp

? Are you sure you want to proceed? [y/N] y
Done!
No errors reported
Stopping database service...


Redefinition of network interfaces

Use the orbit default-interface command to redefine the network interfaces so that the eth0 interface is defined as a member of the cluster.

Usage: orbit default-interface

Configure the default network interface. The application uses this information to determine the host IP.

Flags:
  -h, --help     Show context-sensitive help.

      --force    Force the command execution, never prompt
