dnsmasq

I would like to assign local domain names to the computers on my network
based on their MAC address and thereore automatically have all my local
domains named as part of DHCP. I have two linux systems under a WRT54G
router, one wirelessly connected via a Netgear wg311v3 card and the
other via wire.

I am considering running dnsmasq for this task on the wired
linux box. However, I am wondering two things:

1. Does wlan0 (Netgear card) have a unique MAC address?
2. Will the WRT54G pass dhcp requests from the wireless
network on to the wired network when its DHCP mode is turned
off?

Any help would be wonderful. Thanks!

It should, yes.

It should, yes.

BTW: installing OpenWRT on your wrt54g will give you dnsmasq on
the router. Highly recommended.

Thanks for your help, Stefan.

I've been considering doing just that (installing OpenWRT) but I shy
away in fear of the time required. Is it easy? Are there any advantages
to running dnsmasq there instead of on my linux box? Are there other
(immediate) advantages to installing OpenWRT?

For me the install was very easy, and it made the configuration easier
because I prefer command-lines to web-interfaces. I haven't used
OpenWRT's `webif' so I can't speak for its ease in the case where you
prefer a web interface.

Depends. In my case, I like to turn off my GNU/Linux box whereas the
router is always ON, so the difference is crucial.

> Are there other (immediate) advantages to installing OpenWRT?

It allows you to exercise the freedom provided by the GPL.
In my case I used it to install all kinds of other software on my
router: an NTP server, a web-server (to share pictures of my daughter
with my remote family), a caching http proxy, a backup server,
a jukebox, ...


Stefan "who just had to move things around and is now forced to
use his DSL modem as router, which sucks because it is
(apparently) based on FreeBSD so the manufacturer did
not provide any way to change it, so I can't use
dnsmasq and can't configure it conveniently any more :-("

Thanks for your response, Stefan. I do like the idea, but I'm still more
than a little scared of the install. If it goes well, great - probably
very little time. I can see a glitch, however, ending up costing me
eight hours, and that kind of time I don't have right now.
