如何使用dhcpd分配特定于mac地址的IP地址?
到目前为止我已经尝试过
host blah { hardware ethernet <mac address>; fixed-address <ip address>;}
在我的dhcpd.conf中.但重新启动dhcpd和有问题的mac地址的机器后,我再次获得一个随机IP.
解决方法
这是完美的格式 – 我使用完全相同.只有我在行尾添加注释(另外).这是从dhcpd.conf工作的摘录:
host wrt45gl-etika { hardware ethernet 00:21:29:a1:c3:a1; fixed-address ---.219.43.135; } # MSIE routeris WRT54GL
正如@Christoph所提到的,可能会声明全局选项(或使用服务默认值),这可能会影响IP分配/可能覆盖它的方式.
从dhcp3-server(v3)迁移到isc-dhcp-server(v4)时,我需要添加一些必需的选项并重写一些声明.但配置文件的结构仍然很简单:
# # Sample configuration file for ISC dhcpd for Debian # # The ddns-updates-style parameter controls whether or not the server will # attempt to do a DNS update when a lease is confirmed. We default to the # behavior of the version 2 packages ('none',since DHCP v2 didn't # have support for DDNS.) ddns-update-style none; # option definitions common to all supported networks... option domain-name "mf.vu.---"; option domain-name-servers ---.219.80.11,---.219.80.2,---.171.22.22; default-lease-time 2678400; max-lease-time 2678400; # 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; # The subnet that shares this physical network shared-network TOTAL_MF { server-name "letta.mf.vu.--"; subnet ---.219.43.128 netmask 255.255.255.192 { option routers ---.219.43.190; option broadcast-address ---.219.43.191; group { host wrt45gl-etika { hardware ethernet 00:21:29:a1:c3:a1; fixed-address ---.219.43.135; } # MSIE routeris WRT54GL # ... host saulute { hardware ethernet 00:21:28:10:f4:16; fixed-address ---.219.43.189; } # Virtual Qemu PC NIC } } subnet 172.16.43.128 netmask 255.255.255.192 { option routers 172.16.43.129; option broadcast-address 172.16.43.191; group{ host ligo { hardware ethernet 08:00:20:7A:E2:70; fixed-address 172.16.43.179; } #a225 ligo # ... host vumfsa2 { hardware ethernet 00:80:48:8d:12:f0; fixed-address 172.16.43.140; } # 118 } } }
在那里我没有使用池,没有范围声明.只有两个子网声明(一个后跟另一个).
在那里,我没有分配给我的主机的随机IP,这些IP在这里被声明(与MAC绑定).
