Installing dhcpd

At a terminal prompt, enter the following command to install dhcpd:

# sudo apt install isc-dhcp-server

NOTE: You may need to edit /etc/default/isc-dhcp-server to specify the interfaces dhcpd should listen to.

NOTE: dhcpd diagnostic messages stored in the syslog.

Configuring dhcpd

1. Edit /etc/dhcp/dhcpd.conf, for example:

default-lease-time 600;

max-lease-time 7200;

subnet 192.168.1.0 netmask 255.255.255.0 {

range 192.168.1.150 192.168.1.200;

option routers 192.168.1.254;

option domain-name-servers 192.168.1.1, 192.168.1.2;

option domain-name "mydomain.example"; }

2. After changing the config file, restart the dhcpd.

# sudo systemctl restart isc-dhcp-server.service

3. Clients are found in the lease file.

# cat /var/lib/dhcp/dhcpd.leases

These are the factory default settings:

● Username: admin

● Password: admin

● Network interface: eth1

● IPv4 method: manual

● IPv4 method: 192.168.2.1/24

1. Configure the system you will be using to connect the Edge Gateway with a static IPv4 address.

● The range for the static IPv4 address is 192.168.2.2 to 192.168.2.254.

● Set the subnet to 255.255.255.0.

2. Using an ethernet cable, connect the system with the Edge Gateway.

3. Remote login via ssh session. For example:

# ssh admin@192.168.2.1
