Linux操作系统下配置DHCP服务器教程

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

}

[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.
