Clearswift Server Console allows you to configure network settings, including network interfaces (IP addresses and static routes), hostname, DNS servers and proxy information for the
Unless otherwise advised, it is important that you perform all network configuration directly through the Server Console. Only changes made via Server Console apply to the installed |
You can access the Server Console interface direct via your system console or over an SSH connection. If you want to use an SSH connection, you must first enable SSH access in the
You must use the cs-admin account credentials to access the Server Console interface, regardless of the method of access.
Reconfiguring network configuration settings via SSH could disconnect your SSH connection. Clearswift advises you to use local console for network configuration if available. If you cannot use local console, you should plan your changes carefully to avoid disrupting the network connection you are using for SSH access. |
After accessing Server Console, select Configure System from the list of options. This displays the Configure System page of the Server Console. Configure Network Settings allows you to configure local network settings such as IP addresses, DNS servers, hostname, static hosts, and routes. Configure External Servers allows you to configure external network services such as NTP, SCOM, and SNMP.
Server Console is a menu-driven, text-based user interface (TUI), which you navigate using the keyboard. You can use the Tab and Spacebar keys to quickly navigate between menus and apply changes.
The majority of menus and forms in Server Console follow a standard pattern. From a summary list of network properties (such as Static Hosts) you can select one of three options:
Use this option to add a new item.
Use this option to edit or delete an existing item.
Use one of these options to return to a previous menu without saving your changes.
Use one of these options to save your changes and return to a previous menu. Note: If you return to a previous menu using Save or Done, Server Console saves all changes for you to deploy later in the process.
When you first enter the Configure Network Settings or Configure Network Services menus, the system tracks any changes you make and records changes that require deploying. Server Console deploys changes to network configuration settings as a single step when you exit the Configure Network Settings or Configure Network Services menu.
The Deploy Network Settings page appears and gives you the following options:
This immediately applies all pending changes and restart the network service. Some loss of service or connectivity may be experienced at this time.
This leaves all changes in "pending" state, awaiting further modification. No changes will be lost.
This immediately discards all pending changes.
When you select Apply, Server Console automatically deploys all changes to local network settings. At the point deployment occurs, the installed

Server Console has a number of menus that mention IPv6. Although these menus appear in Server Console, they are currently inactive as IPv6 support is not available in the current release.
Network Adapters settings offers you a list of recognized network interfaces. If a new network adapter is added, the kernel automatically detects it and a new entry is displayed in the list of network interfaces.
You cannot configure a network interface until you physically install it and the kernel recognizes it. This means you cannot add a new network interface via Server Console. You can only edit network interfaces that are physically installed and recognized by the kernel. |
Server Console lists network interfaces as either Enabled or Disabled. Interfaces that you have not yet configured appear as disabled. When you edit an interface, you have the option to enable/disable it.
Each Enabled interface must have a unique IP address. Never Enable and deploy two interfaces with identical IP addresses, unless you have been instructed by Clearswift Technical Support to do so. |
To configure a new network interface or modify an existing one, select a network interface and click Edit. The Server Console then presents you with a list of configuration changes you can make to the network interface. You can add or edit IPv4 addresses and IPv4 static routes or you can disable the network interface.
Each physical network interface (or adapter) can have a Primary and Secondary IP address. A Secondary IP address is sometimes called a virtual-IP or IP-alias. When you first configure a network interface, the Server Console forces you to configure the Primary IP address first. You can only add the Secondary IP address once you define the Primary. Once both addresses are defined, you can delete either the Primary or Secondary IP address. If you delete the Primary IP address, the network interface still works with the Secondary IP address. The Server Console only supports one Secondary IP address. For example, the IP address associated Ethernet interface eth0 is the Primary IP address and the eth0:1 the Secondary IP address.
You can make changes to local network settings such as IP address, DNS server, Hostname, Static Hosts and Routes in the Configure Network Settings menu.
You can change the hostname of the
The Network Adapters menu allows you to browse all the physical NICs detected by the kernel. You can configure up to two IPv4 addresses on each NIC and also configure any associated static routes.
In an environment with two or more NICs, the Server Console enables you to define a different default

The Server Console allows you to register up to four SCOM servers. For each SCOM server, you must supply the user account details (username and password) used by the SCOM servers for importing SCOM management packs. Your password must conform to the password policy being enforced. See Clearswift password policy for local accounts for more information.
