[Dnsmasq-discuss] How to get name of DHCP'ed system?

[Chris G]

I have just moved fully to using dnsmasq on my xubuntu 8.10 system,
it's made things much simpler than they were.  I have removed all my
manually added entries for static IP hosts on the LAN from /etc/hosts
and I've "un static IP'ed" them - dnsmasq does it all for me.

However I have one issue, I have a couple of things which are not
computers on the LAN, there's an HP printer and a Siemens DECT/VOIP
box.  I have set them to use DHCP to get their settings but I don't
know how to find what their names are.

It's easy for a computer on the network, I have set the name when
installing the OS so I know what the name is.  But I don't know how to
find the name of a box whose name I'm not able to set myself.

How can I find DNS names of systems which dnsmasq knows about?
