Global configuration
Access configuration file
The main configuration file is /etc/dhcp/dhcpd.conf
vim /etc/dhcp/dhcpd.conf
Static IP @
This new configuration will ONLY accept known clients and give them a static IP @.
# Sample /etc/dhcpd.conf
# (add your comments here)
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 172.16.50.255;
option routers 172.16.50.254;
option domain-name-servers 172.16.50.2, 8.8.8.8;
option domain-name "mydomain.lan";
option ntp-servers 172.16.50.254;
deny unknown-clients;
subnet 172.16.50.0 netmask 255.255.255.0 {
host client1 {
hardware ethernet DD:GH:DF:E5:F7:D7;
fixed-address 172.16.50.20;
}
host client2 {
hardware ethernet 00:JJ:YU:38:AC:45;
fixed-address 172.16.50.21;
}
}Note:
The deny unknown-clients; command is why only known clients are accepted.
For each client you have to adjust:
- MAC @
- Set a specific static IP @
Add new host
Configuration file
Edit the configuration file:
vim /etc/dhcp/dhcpd.conf
Declare new host
Add new host at the end of the file :
host myNewHost {
hardware ethernet 00:0e:af:31:d1:cc;
fixed-address 172.16.50.60;
option host-name "myNewHost";
}==> Don't forget to the given IP @ must match the DNS server declaration !
Take on changes
Restart the DHCP server :
/etc/init.d/isc-dhcp-server restart
