在哪查看 dhcp 租约信息 ? 如何让 dnsmasq dhcp 在 192.168.0.1 而非 0:0:0:0 ?

[station]

虚拟机客户端 dhcp,没 google 到这方面的信息

主机在搭建 nas+软路由: 调试配置中 dnsmasq 是在 0:0:0:0 上进行 dhcp 而非 192.168.0.1 上,google 没有什么收获...

@exkernel 我想说结果一样, dnsmasq dhcp server 还是在 0:0:0:0 上监听

狂且我本就是如此写的 conf 文件

[xfspace]

# If you want dnsmasq to listen for DHCP and DNS requests only on
# specified interfaces (and the loopback) give the name of the
# interface (eg eth0) here.
# Repeat the line for more than one interface.
#interface=
# Or you can specify which interface _not_ to listen on
#except-interface=
# Or which to listen on by address (remember to include 127.0.0.1 if
# you use this.)
#listen-address=
# If you want dnsmasq to provide only DNS service on an interface,
# configure it as shown above, and then use the following line to
# disable DHCP and TFTP on it.
#no-dhcp-interface=

# On systems which support it, dnsmasq binds the wildcard address,
# even when it is listening on only some interfaces. It then discards
# requests that it shouldn't reply to. This has the advantage of
# working even when interfaces come and go and change address. If you
# want dnsmasq to really bind only the interfaces it is listening on,
# uncomment this option. About the only time you may need this is when
# running another nameserver on the same machine.
#bind-interfaces


都试试？

bind-interfaces
需要写多这一条

dhcp 租约需要加一句
log-dhcp
然后在输出日志上可以 tail 到详细的租约信息（最好注释掉 log-queries ）

[station]

@xfspace 就是如此才是最恶心的

[station]

@predator 看我刚回复的

客户机是台虚拟机,配合家庭服务器(nas+软路由)在调试配置
so 我需要查看 dhcp 信息( 租约和续租时间 )

[predator]

就两条配置就够了啊

log-dhcp
log-facility=/var/log/dnsmasq.log

然后再上面指定的日志文件里面就可以拿到详尽的 dhcp 信息：

还有一个你可能用得上的是：

dhcp-leasefile=/var/log/dhcp.leases

这里可以记录到全部客户端的租约信息

[jasontse]

DHCP 要接收广播消息，怎么可以限定地址。

[lazycat]

DHCP 获取到地址之前客户端本身是没有 IP 地址的。。。先不说能不能限制如果你真做到了把 dnsmasq 限制监听 192.168.0.1 这个段后果就是新设备全部无法获取 IP 地址上不了网除非你手动分配一个这个网段的 IP，不过手动分配的话还要 DHCP 有什么用呢。。。

不如 mac 绑定吧
