Linux操作系统下如何配置DHCP服务器

[root@localhost RPMS]# cat /etc/dhcpd.conf 

ddns-update-style interim;

ignore client-updates;

subnet 192.168.1.0 netmask 255.255.255.0 {

        option nis-domain               "domain.org";

        option domain-name              "abc.com";

# -- you understand Netbios very well

        default-lease-time 21600;

        }

}

[root@localhost RPMS]# cat /var/lib/dhcp/dhcpd.leases   在服务器上查看已经分配出去的IP

# All times in this file are in UTC (GMT), not your local timezone.   This is

# not a bug, so please don't ask about it.   There is no portable way to

# store leases in the local timezone, so please don't request this as a

# feature.   If this is inconvenient or confusing to you, we sincerely

# apologize.   Seriously, though - don't ask.
