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 networkshared-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).
