dyhcpd replaced with dnsmasq - but users not authenticating

[Sergio Dicandia]

Hi Gavin,

here is my tcpdump; I hope it will help to find out what's wrong (I'm no network expert ...)
I'll send the dnsmasq.cond asap as well

Thanks again,
Sergio

Great.  Could you post your dnsmasq config so we can record how this is
done?

That's curious.  Could you run tcpdump on the server something like
    tcpdump -i eth0 host w.x.y.z and tcp port 22

to see does the client successfully make an ssh connection to the server?
Put the client's ip address in place of w.x.y.z obviously.
