Gentoo 下 DHCP 的設定

目的: 建立起 DHCP server，讓所有接上這個網域的電腦能不需 config 即可連上網路。
說明: DNS 為 168.95.1.1，domain 為 posiedon。網段為 192.168.0.0/24，其中 254 給 server，1 保留，因此分配出去的 IP range 為 2 - 253

首先，安裝 dhcpcd
emerge dhcpcd

接下來，編輯 /etc/dhcp/dhcpd.conf

# dhcpd.conf 
# 
# Sample configuration file for ISC dhcpd 
# 

# option definitions common to all supported networks... 
option domain-name "poseidon"; 
option domain-name-servers 168.95.1.1; 
option routers 192.168.0.254; 
ddns-update-style none; 

default-lease-time 600; 
max-lease-time 7200; 

# If this DHCP server is the official DHCP server for the local 
# network, the authoritative directive should be uncommented. 
#authoritative; 

# Use this to send dhcp log messages to a different log file (you also 
# have to hack syslog.conf to complete the redirection). 
log-facility local7; 

# No service will be given on this subnet, but declaring it helps the 
# DHCP server to understand the network topology. 

# A slightly different configuration for an internal subnet. 
subnet 192.168.0.0 netmask 255.255.255.0 { 
range 192.168.0.2 192.168.0.253; 
}

最後，啟動 DHCPD
/etc/init.d/dhcpd start

加入開機即起動的行列
rc-update add dhcpd default
