[Dnsmasq-discuss] dhcp requests not answered

[John Zbesko]

Recently, my ISP (Comcast cable) announced they were switching to
dynamic DNS. So, I presume I could use dnsmasq on my Sun Ultra 1,
running Debian, to serve DHCP requests and provide the DNS server
address to my home network of Linux and Windows XP machines. I also use
two Netgear gigabit switches to connect the Ultra in the basement with
the PC's on the 1st and 2nd floors (and a wireless router for laptops
with a static IP of 192.168.1.1)

My DHCP server works fine. However, dnsmasq does not offer addresses, no
matter what options I try in dnsmasq.conf.

I believe the operative lines in dnsmasq.conf are:

domain-needed
bogus-priv
filterwin2k
listen-address=192.168.1.251,127.0.0.1 #Ultra 1 server static IP facing
home network
dhcp-range=192.168.1.2,192.168.1.254,255.255.255.0,infinite

dhcp-host=00:02:44:ab:da:fb,Zgate,192.168.1.254,infinite
dhcp-host=00:50:8d:d7:ad:66,Zamd64,192.168.1.247,infinite
dhcp-host=00:e0:7d:f2:7c:91,compaz,192.168.1.252,infinite
dhcp-host=00:02:a5:68:82:cf,TOFU,192.168.1.248,infinite
dhcp-host=00:09:5b:65:00:a8,emachine,192.168.1.249,infinite

#These are the various x86 PC's in my household.

dhcp-option=19,0           # option ip-forwarding off
dhcp-option=44,0.0.0.0     # set netbios-over-TCP/IP nameserver(s) aka
WINS server(s)
dhcp-option=45,0.0.0.0     # netbios datagram distribution server
dhcp-option=46,8           # netbios node type
dhcp-option=47             # empty netbios scope.

log-queries

My syslog shows this when dnsmasq is started, but no sign of requests
from any other PC's on my network:

Mar  2 02:03:11 localhost dnsmasq[6065]: started, version 2.22 cachesize
150
Mar  2 02:03:11 localhost dnsmasq[6065]: DHCP, IP range 192.168.1.2 --

68.87.72.130#53
Mar  2 02:06:08 localhost dnsmasq[6065]: exiting on receipt of SIGTERM


Where does "log-queries" send its output to? The "exiting" results from
me stopping dnsmasq so I can restart the dhcp server-and send this
email. Any help is greatly appreciated.
