The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to assign IP addresses and provide configuration information to devices such as servers, desktops, or mobile devices, so they can communicate on a network using the Internet Protocol (IP).
Step-by-step guide
Install the package using apt-get tool.
Installing the package
root@dilos:~# apt-get install isc-dhcp-server
Edit the configuration file /etc/dhcp/dhcpd.conf for IPv4 or /etc/dhcp/dhcpd6.conf for IPv6.
IPv4 example
#A slightly different configuration for an internal subnet.
subnet 192.168.0.0 netmask 255.255.255.0 {
pool {
range 192.168.0.100 192.168.0.200;
option domain-name-servers ns1.internal.example.org;
option domain-name "internal.example.org";
option routers 192.168.0.254;
option broadcast-address 192.168.0.255;
default-lease-time 600;
max-lease-time 7200;
}
}
Edit the configuration file /etc/default/isc-dhcp-server for IPv4 or for IPv6. Find out the name of the network interface - ifconfig. Now you can run the server:
# Defaults for isc-dhcp-server (sourced by /etc/init.d/isc-dhcp-server) # Path to dhcpd's config file (default: /etc/dhcp/dhcpd.conf). #DHCPDv4_CONF=/etc/dhcp/dhcpd.conf #DHCPDv6_CONF=/etc/dhcp/dhcpd6.conf # Path to dhcpd's PID file (default: /var/run/dhcpd.pid). #DHCPDv4_PID=/var/run/dhcpd.pid #DHCPDv6_PID=/var/run/dhcpd6.pid # Additional options to start dhcpd with. # Don't use options -cf or -pf here; use DHCPD_CONF/ DHCPD_PID instead #OPTIONS="" # On what interfaces should the DHCP server (dhcpd) serve DHCP requests? # Separate multiple interfaces with spaces, e.g. "eth0 eth1". INTERFACESv4="vnic1" INTERFACESv6=""
starting the service
root@dilos:~# svcadm enable isc-dhcp-server
Check the result by svcs tool:
Checking problem services
root@dilos:~# svcs -xv root@dilos:~#
That means the service works, and you may relax 
If you see some services in the output of svcs -xv, this means the services were configured incorrect. Check their configuratiuon files and then try to do command svcadm clear service
