Now, to my issue: I've been asked to setup a little WLAN for free
"Computers 101" courses, and the WLAN does not have any kind of
security (not my choice, BTW...). As you can imagine,
an open WLAN is VERY attractive for freeloaders.

I've been adding "dhcp-host=mac-address,ignore" entries for a while, but
I've been wondering if I could, for example, ignore all DHCP requests
from hosts with a client name like
"android-" (because we're not teaching "how to use
your Android smartphone", hence it must come from freeloaders)



You could maybe look at '-6 --dhcp-script=':

do you mean that dnsmasq only increments the serial when a SIGHUP is received 
*OR* it increments the serial any time it is (re)started?

OK, I'm confused about the serial problem. I just tested here, and it
works as I described.

Could you post you complete config here, or mail it direct to me?


Cheers,

Simon.
