<p class=MsoNormal>Hi, All:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am a new user of DNSMASQ, and I have the DNS portion
working great! What a great tool, and so easy!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However, I’m struggling with the DHCP portion. This
is being run on a linux server in my small network, and DHCP has been supplied
by the cable modem. (I did turn off DHCP at the modem.) I have
decided to start small – connecting with an UBUNTU laptop – but my dhclient
eth0 requests consistently end with “No DHCPOFFERS received.”
I’ve been through the past year of your logs, looking at subjects
including DHCP and didn’t find a hit, so I’ve come here.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My configuration is simple for now:<o:p></o:p></p>
<p class=MsoNormal>domain-needed<o:p></o:p></p>
<p class=MsoNormal>bogus-priv<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> ( also added the following line to see if that would
improve the situation, but no joy… :<o:p></o:p></p>

<p class=MsoNormal>What might I be missing? How can I diagnose? I’ve
found a few troubleshooting tips online, but they all seem to point to
configurations like this one, so I’m baffled. (I did find a
question about iptables, but couldn’t decipher how to determine if that’s
a problem.) FTR, my associated iptables lines look like:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> # and allow DHCP<o:p></o:p></p>
<p class=MsoNormal> iptables -A INPUT -p UDP --dport bootpc
-j ACCEPT || die<o:p></o:p></p>
<p class=MsoNormal style='text-indent:9.0pt'>iptables -A INPUT -p UDP --dport
bootps -j ACCEPT || die<o:p></o:p></p>
<p class=MsoNormal style='text-indent:9.0pt'><o:p> </o:p></p>
<p class=MsoNormal>I welcome any advice.<o:p></o:p></p>
