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。但是在重新启动 dhcpd 和具有相关 mac 地址的机器后,我再次获得了一个随机 IP。
这是非常好的格式——我用的完全一样。只有我在行尾附加了评论(另外)。这是工作的摘录dhcpd.conf:
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(或使用的服务默认值),这可能会影响分配 IP 的方式/可能会覆盖它。
在从dhcp3-server (v3)迁移到isc-dhcp-server (v4) 时,我需要添加一些强制选项并重写一些声明。但是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;

}

在那里我使用了 no pool,没有range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 在这里声明(与 MAC 绑定)。
