I want to use dhcp server.

but do not run function.

[/etc/config/network]

config 'interface' 'loopback'
        option 'ifname' 'lo'
        option 'proto' 'static'
        option 'ipaddr' '127.0.0.1'
        option 'netmask' '255.0.0.0'

config 'interface' 'lan_l'
        option 'type' 'bridge'
        option 'ifname' 'eth0.0'
        option 'proto' 'static'
        option 'ipaddr' '192.168.200.11'
        option 'netmask' '255.255.255.0'
        option 'gateway' '192.168.200.1'
        option 'defaultroute' '0'
        option 'peerdns' '0'

config 'interface' 'lan_r'
        option 'type' 'bridge'
        option 'ifname' 'eth0.1'
        option 'proto' 'dhcp'
        option 'ipaddr' '192.168.200.11'
        option 'netmask' '255.255.255.0'
        option 'dns' ''

[/etc/config/dhcp]

config 'dnsmasq'
        option 'domainneeded' '1'
        option 'boguspriv' '1'
        option 'localise_queries' '1'
        option 'domain' 'lan'
        option 'expandhosts' '1'
        option 'authoritative' '1'
        option 'readethers' '1'
        option 'leasefile' '/tmp/dhcp.leases'
        option 'resolvfile' '/tmp/resolv.conf.auto'
        option 'local' '/lan_l/'

config 'dhcp'
        option 'interface' 'lan_l'
        option 'start' '100'
        option 'limit' '150'
        option 'leasetime' '12h'
        option 'dynamicdhcp' '1'

I have similar problem, but I don't like luci,uci, webif, therefore only manual settings for me.

My interesting is about this dnsmaq option:

    --dhcp-hostsfile=<filename>     Read DHCP host specs from file

Where I set this? In /etc/config/dhcp?
What is the correct syntax of <filename>?

I have wgt634u with 8.09.
Thanks, Luca.

You could either set this in /etc/dnsmasq.conf with a line saying "dhcp-hostsfile=/path/to/your/file" (there are no double dashes in front of the option when it appears in that config file) or in /etc/config/dhcp in the "config dnsmasq" section with a line like

    option    dhcphostsfile    /path/to/your/file

(note the absence of a dash)

I would probably prefer setting it in /etc/config/dhcp, since that is more openwrt-like and can easily be operated on with uci.

Concerning the syntax, http://www.thekelleys.org.uk/dnsmasq/do … q-man.html says it is the same as what you would put after the --dhcp-host= option, one entry per line.

But pondering on that, if you don't really need an extra file and if you also don't need any of the fancier features of the --dhcp-host option, you should probably consider not using the dhcphostfile option at all and just put all the hosts into /etc/config/dhcp. You do that by creating one section for each host you want to define. Like that:

config host
    option name    foobar
    option mac    00:01:23:ab:cd:ef
    option ip    192.168.1.45
    option dhcp_option    42,192.168.1.1

Option mac and option ip are mandatory. Option name and option dhcp_option are optional, but name is required if you want any of your dhcp_option lines in that section to have an effect.

Since I for myself only need to map mac addresses to hostnames (the hostnames are mapped to ip addresses in my /etc/hosts file), I don't even need that possibility, I just use an /etc/ethers file instead.

thanks you very much for complete details!

I have another question about dnsmasq config. In my /etc/config/dhcp i have this options

config dnsmasq
       ...
       option expandhosts    1
       ...


config host
        option name             pippo
        option mac              XX:XX:XX:XX:XX:XX
        option ip               192.168.1.2

I think that expandhost setting read only /etc/hosts, and not "config host".
In my client and router i have only "127.0.0.1 localhost" in /etc/hosts, and if I ping my router (it name is openwrt) i get:

#> ping openwrt
ping: unknown host openwrt

Is correct this behaviour? the only way for resolv the name of my clients is insert there in /etc/hosts in my router?
