DPOD can be configure with two network interface :

1. First Interface - For accessing DPOD's Web Console via web browser and DPOD's CLI via SSH.
2. Second Interface - For communicating with the monitored devices.

Connect the Second Network Interface to the Server

Use your system administrator assistance to add a second network interface to your virtual machine or physical server.

In some cases there will be a need to restart the server before the new network will be available.

After the server restart,  the operating system will automatically configure the new network interface  using DHCP.

Log in to DPOD's Console or CLI via SSH with the user "root"  and type the command "ifconfig"

The new network interface should be displayed as "eth1"

Configure the New Network Interface

1. Copy the network interface MAC address as displayed in the "ifconfig"  command output after the attribute "ether"
   
   

2. change directory to /etc/sysconfig/network-scripts
   
   

   cd /etc/sysconfig/network-scripts

3. duplicate the eth0 (first network interface) network interface configuration file for the new network interface file (eth1)
   
   

    cp ifcfg-eth0 ifcfg-eth1 

4. Edit the new file (ifcfg-eth1) and alter the following attributes based on the new network interface properties
   
   

   DEVICE=eth1
   BOOTPROTO=static
   ONBOOT=yes
   NM_CONTROLLED=no
   HWADDR=00:0c:29:14:7a:88
   IPADDR=192.168.1.178
   NETMASK=255.255.255.0
   USERCTL=no
   DNS1=8.8.8.8
   DNS2=8.8.4.4
   IFCONFIG_OPTS="txqueuelen 10000"

   
   DEVICE     : The network interface device name should be eth1
   HWADDR  : The network interface MAC address as displayed at section 1.
   NETMASK : The network mask based on the new interface properties (the network administrator should supply this information)
   
   

5. Restart the network service by entering the following command

   service network restart
   The command output should be : Restarting network (via systemctl):                        [  OK  ]

6. Use the command "ifconfig" to make sure the new network interface is up and configured with the correct IP address
   
   
   If the new IP address is not displayed restart the server.

Configure Routing

In order to support the second network interface a new routing table and routing rule should be defined.

Create New Routing Table

1. Edit the file /etc/iproute2/rt_tables and add new routing table entry with id "1" named "rt1"
   
   

   
   

2. In order to add new routing entry to the new routing table use the "ip route" command.
   This command will add new temporary entry to the routing table.

3. Add a default gateway entry :
   
   

   default via <interface default gateway> dev <interface name> table <routing table name>

   
   Example : For adding the default gateway 192.168.1.1 to interface eth1

   ip route add default via 192.168.1.1 dev eth1 table rt1

   
   After confirming the needed network connectivity to the monitored device.
