KONFIGURASI DHCP LINUX

Cara Instalasi seperti biasa :

# cd /usr/src

# installpkg dhcp-3.0.4-i486-2.tgz

Setelah selesai,Anda langsung edit aja file konfigurasinya sebagai berikut :

# ISC DHCP-Server Configuration
# /etc/dhcpd.conf
#
default-lease-time 86400 ; # one day
max-lease-time 604800 ; # one week
ddns-update-style ad-hoc ;
ddns-updates on;
option ip-forwarding off;
option routers 192.168.2.1 ; # important when this corresponds to: ‘gateway’
option subnet-mask 255.255.255.0 ;
ignore client-updates ;
option broadcast-address 192.168.2.255 ;
option domain-name “mydomain.com” ;
option domain-name-servers 194.22.190.10 , 194.22.194.14; # important when this corresponds to : ‘DNS Servers’

#

# LAN
subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.40 192.168.2.60;
}

# DMZ
subnet 192.168.3.0 netmask 255.255.255.0 {
range 192.168.3.40 192.168.3.60;
}

#

# List an unused interface here
subnet 192.168.1.0 netmask 255.255.255.128 {
}

Kemudian test, mode debug :

shell> killall dhcpd

shell> dhcpd -d &

Cek script init untuk dhcp di :

/etc/rc.d/rc.local
sh ./rc.dhcpd start

Jika belum ada file rc.dhcpd, buat sendiri. misalnya seperti ini :

#!/bin/sh
#
# /etc/rc.d/rc.dhcpd
#
# Start/stop/restart the DHCP daemon.
#
# To make dhcpd start automatically at boot, make this
# file executable: chmod 755 /etc/rc.d/rc.dhcpd
#
