hey,
I'm using kamikaze 7.07 on wrt54gl.
I want dnsmasq to serve IP addresses in a range from 192.168.0.150 to 192.168.0.200 inside my private network.

here is my /etc/config/dhcp

config dhcp
        option interface        lan
        option start     150
        option limit     200
        option leasetime        12h

but logread says the following:

Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: started, version 2.38 cachesize 150
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: compile time options: IPv6 GNU-getopt ISC-leasefile no-DBus no-I18N TFTP
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: DHCP, IP range 192.168.0.150 -- 192.168.0.253, lease time 12h
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: using local addresses only for domain lan
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: reading /tmp/resolv.conf.auto
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: using nameserver xxx.xxx.xx.xx#53
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: using nameserver xxx.xxx.xx.xx#53
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: using local addresses only for domain lan
Sep  2 15:54:01 OpenWrt daemon.info dnsmasq[492]: read /etc/hosts - 1 addresses
Sep  2 15:54:01 OpenWrt daemon.err dnsmasq[492]: failed to read /etc/ethers:No such file or directory

and nvram shows:

root@OpenWrt:~# nvram show | grep dhcp
size: 3172 bytes (29596 left)
dhcp_start=150
dhcp_num=50

Is there anything I've missed??
thank you.

First, Kamikaze does not use NVRAM at all. To configure you have to use UCI (or edit /etc/config/dhcp manually with a editor).

To configure a pool from 192.168.0.150-200, do this:

uci set dhcp.cfg1.start=150
uci set dhcp.cfg1.end=50
uci del dhcp.cfg1.limit
uci commit dhcp
/etc/init.d/dnsmasq restart

EDIT: There is a bug in 7.07 (which is fixed in trunk). A workaround is to use the 'end' option instead of 'limit' in the config.

Sep  2 17:00:47 OpenWrt daemon.info dnsmasq[681]: DHCP, IP range 192.168.0.150 -- 192.168.0.200, lease time 12h

Hi!

This works for me on 7.09... (wrt54g V2)

config dhcp
        option interface        lan
        option start     100
        option limit     50
        option leasetime        12h

I get DHCP range: from 192.168.1.100 to 192.168.1.150

Doesn't seem to work with option end though...

You could use /etc/dnsmasq.conf instead.  Here is an edited version of mine which should work based on the above.  It serves addresses between 192.168.1.200 and 192.168.1.250.

==== start =
# filter what we send upstream
domain-needed
bogus-priv
filterwin2k
localise-queries

# allow /etc/hosts and dhcp lookups via *.lan
local=/lan/
domain=lan
expand-hosts

# enable dhcp (start,end,netmask,leasetime)
dhcp-authoritative
dhcp-range=192.168.1.200,192.168.1.250,255.255.255.0,24h
dhcp-leasefile=/tmp/dhcp.leases

# use /etc/ethers for static hosts; same format as --dhcp-host
# <hwaddr> [<hostname>] <ipaddr>
read-ethers

# other useful options:
# default route(s): dhcp-option=3,192.168.1.1,192.168.1.2
#    dns server(s): dhcp-option=6,192.168.1.1,192.168.1.2

==== end =

I then replace /etc/init.d/dnsmasq with the following script.  It kills any running dnsmasq before starting a new dnsmasq. It isn't pretty but it works.

==== start =
#!/bin/sh /etc/rc.common

if ps | grep /usr/sbin/dnsmasq | grep -v grep >/dev/null
then
kill `ps | grep /usr/sbin/dnsmasq | grep -v grep | awk '{print $1}'`
fi

if [ -f /tmp/dhcp.leases ]
then
rm /tmp/dhcp.leases
fi

/usr/sbin/dnsmasq
==== end =
