求查看dhcp配置参数的方法

Question

有什某命令查看dhcp运行参数，如地址池的大小等

Answer 1

很遗憾，我找了很久，也没有isc发布的dhcpd有相关的系统工具，这方面就不如AIX上IBM写的dhcpsd了
我想你只能够先读完文档，了解各个参数的默认值，然后看看dhcpd.conf里有没有指定，如果没有，那么就是默认值大小了

举个例子

[root@linux ~]# cp /usr/share/doc/dhcp-*/dhcpd.conf.sample /etc/dhcpd.conf
[root@linux ~]# vi /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
not authoritative;　

If this DHCP server is authoritative for that subnet,
please write an `authoritative;' directive either in the
subnet declaration or in some scope that encloses the
subnet declaration - for example, write it at the top
of the dhcpd.conf file.

subnet 192.168.1.0 netmask 255.255.255.0 {　

# --- default gateway
        option routers                  192.168.1.1;　
     option subnet-mask              255.255.255.0;

        #option nis-domain              "domain.org";　
        option domain-name-servers      192.168.1.1;
　   option domain-name-servers      XXX.XXX.XXX.XXX,XXX.XXX.XXX.XXX;
     option time-offset              -18000; # Eastern Standard Time
#       option ntp-servers              192.168.1.1;
#       option netbios-name-servers     192.168.1.1;
# --- Selects point-to-point node (default is hybrid). Don't change this unless
# -- you understand Netbios very well
#       option netbios-node-type 2;

        range dynamic-bootp 192.168.1.2 192.168.1.254;　
        default-lease-time 21600;
        max-lease-time 43200;

        # we want the nameserver to appear at a fixed address
        #host ns {　
        #       next-server marvin.redhat.com;　
        #       hardware ethernet XX:XX:XX:XX:XX:XX;　
        #       fixed-address 207.175.42.254;　
        #}　
                host win-client1 {　
               hardware ethernet XX:XX:XX:XX:XX:XX;　　
               fixed-address 192.168.1.10;　
        }
}

[root@linux ~]# /etc/rc.d/init.d/dhcpd start

看DHCP的配置文件!
