isc dhcpd 3.0 快速安装实例

2003.06.19

目的：
为内网提供dhcp服务,每个网卡一个网段；
平台：
FreeBSD 5.1 + ports

#程序安装
cd /data/usr/ports/net/isc-dhcp3
make clean install clean

###配置
#/usr/local/etc/dhcpd.conf.sample 是个很好的参考文件；

###########
#注意：一下配置的多个网段，分别对应服务器上多个网卡的地址段，而不是单一网卡上的多个地址（address alias 地址别名）；
#如果你有某网卡设置多个地址，而配置文件中分别给这些网段设置了subnet（这是很多人所谓的”多网段dhcp地址分配“），那么启动
#dhcpd时，会收到如下错误,一般是发送到/var/log/messages：
#Jun 19 14:49:14 mail dhcpd: Interface fxp1 matches multiple shared networks

# should not also be listed as being available for dynamic assignment.
# Hosts for which fixed IP addresses have been specified can boot using
