ScopTEL DHCP Server

ScopTEL -DHCP Server Configuration


Console - ifconfig


A newly installed server uses DHCP to get an IP address from a DHCP server on the network so make sure the public network interface is connected to the network so the server can get an IP address.
Before you can login to the server you must know the IP address of at least one physical interface.
From the Linux console login prompt, enter username ‘root’ omitting any quotation marks.
From the password prompt enter the default root password ‘scopserv’ omitting any quotation marks.
Once you are successfully logged as root type the command ‘ifconfig’ to determine at least one eth interface .
In this example the eth0 IP address is 192.168.192.60 Also notice that the HWaddr is the MAC address of the eth0 interface.




Console – nmtui


If there is no DHCP server on the network the server will not get an IP address.
Using the command ‘nmtui’ omitting any quotes an IP address can be set statically and then used to login to the GUI.




Use the tab key on the keyboard to select Edit a connection





Use the tab key on the keyboard to select the desired interface and press Enter





Use the tab key and keyboard arrows on the keyboard to select elements.
The Default is Automatic (DHCP)
To edit this connection Tab to <Automatic> and press Enter
Tab to Manual and press Enter





Keep using the keyboard to enter any static configurations, then tab or use arrows to select OK and press Enter
After pressing Enter use the <Back> button to exit nmtui





Console – service network restart

From the root prompt type ‘service network restart’ omitting any quotes to restart the network with the new static IP address.



Network Module – Web GUI Login


Once logged into the GUI the eth1 interface must be configured in order to enable routing.
The ifconfig command displays the MAC address of eth1 which is needed to add another network interface to the system.
The eth1 MAC address in this example is 00:E0:81:D8:5D:BD.



Server Module – Network LAN Configuration

Set the Fully Qualified Domain Name (FQDN) for the local system.
Set the network configuration as static.

NOTE:  The system is a fully capable DNS server and can resolve DNS for the network but a third party DNS server can also be used.



Network Configuration – Network Interfaces

From the Configuration>Network>Interfaces tree edit your LAN interface.


Network Configuration – LAN Interface

In this example the eth0 configuration is 1000.scopserv.local and the eth0 LAN interface is 172.16.1.1/16.
Edit the eth interface and substitute the IP address and subnet mask and MAC address for your network requirements.
When finished click on Save.
