Digital Alert Systems DASDEC II User Manual page 33

Second network interface option
Tables at the bottom of the Setup Network Configuration page show the current network routing
table, static routes, address configuration, and the /etc/hosts file. This information is provided to help
with network configuration and troubleshooting. The information is directly generated from Linux
network status applications and reflects the actual state of the DASDEC II network configuration. If the
network configuration is damaged, it is possible for the information in this table to not match the
configured values displayed in the user interface fields. The information in this table is definitive and
accurate.
Perhaps the most useful information is provided within the Current Network Configuration section.
Under the eth0 table is the IP address as the Linux OS sees it. This is the value provided next to the
label "inet addr:". When a second network is enabled, a separate table will be shown for eth1.
This simple interface allows statically defined network routes to be enabled or disabled and
added/deleted at network startup. Click the toggle box to Enable/ Disable a specific static route.

IMPORTANT!
You must be CAREFUL when configuring a static network address if you are
configuring from a remote host. If an address which is inaccessible to your network is accepted for
the DASDEC II, you will not be able to log back in from the remote host.
The Second Network Interface checkbox below the main Network configuration box controls use
of an optional second network interface. The default is value for this option disabled. Check to
enable display of a configuration interface for a second Network Interface Card (NIC) adapter.
As stated above, this interface will display in green and show a status label "2nd Network is
Enabled" when the adapter has been properly installed and configured. When enabled, it will also
display the IP address currently in use for the adapter.
Configuration of the second network adapter is similar to the main network. You must choose a
Network Type from Static (Manually Configure) or Automatic (via DHCP). If Manual Configuration is
chosen, enter the IP Address and the Netmask. The network part of the IP address for the second
network must be unique compared to the main interface network! Otherwise, either interface will
probably not function. For example, if the main network is 10.0.1. #, an obviously separate network
would be 192.168.1. #. There is not a separate DNS to configure for the second network. You can
also optionally set the hostname for the second network as it appears in the Linux /etc/hosts file.
When options have been configured, you must click
